　　　　On June 18, 2013, Huawei officially launched the world’s thinnest smartphone in London, UK.Huawei Ascend P6This model can be said to beHuawei mobile phoneThe beginning of the transformation is also a boutique masterpiece that has dedicated its efforts. After a year,Huawei Ascend P7Officially met us, compared to P6Ascend P7The portrayal in the details is more perfect, or on the way to perfection, Zhongguancun Onlinecell phoneThe Communications Division also brought the first test of this model to netizens for the first time.

HuaweiAscend P7first test

　　　　Before we start the evaluation, we might as well review the general parameters of this model. After all, as a smartphone, the hardware foundation is very necessary. With a good hardware foundation, we can create more and better experiences.

　　　　From the above parameters, it is not difficult to see that HuaweiAscend P7Compared with the previous Ascend P6, there are many upgrades, such as a 5-inch full high definition screen, a new HiSilicon Kirin 910T processor, a 8 million + 13 million pixel dual camera and a new Emotion UI 2.3.

HuaweiAscend P7

　　　　Of course, in addition to performance and experience improvements, HuaweiAscend P7In terms of appearance, it basically maintains the overall style and design language of the Ascend P6, but there are many changes in the details, which are better than the previous visual effects and more user-friendly. This is also the origin of the title of this article, because HuaweiAscend P7There are indeed more or less improvements in all aspects, and these advances have improved the user experience by a level.

　　　　If you are rightHuawei Ascend P6If you are familiar with it, you will see this one for the first time.cell phoneYou can be sure that this is the sequel to the P series, because of their design language and overall styling.Huawei Ascend P7The "family-style front face" design is adopted. Of course, the author thinks it is more appropriate to change it to the "family-style fuselage" design.

HuaweiAscend P7Adopted a piece5 inchesscreen

　　　　HuaweiAscend P7It uses a 5-inch full high definition in-cell screen, and the machine also uses Corning’s third-generation gorilla glass to protect the screen. To be honest, after the author has come into contact with many touch screen models, Corning Gorilla is not only excellent in scratch resistance and wear resistance (the third-generation scratch resistance capacity enhancement 300%), but also better in touch and texture than ordinary glass. Of course, as the foundation of the screen, HuaweiAscend P7The display effect is indeed satisfactory, whether it is color reproduction, screen brightness, or viewing angle, it is excellent. The fully fitted screen also makes the entire screen more transparent and more intuitive.

The screen ratio has increased

　　　　In terms of details, HuaweiAscend P7There are also many changes, giving the author the most intuitive impression is the increase in screen ratio, compared to the pastAscend P7The screen ratio is higher, and the visual impact of the whole machine is also improved. With the 2.97mm ultra-narrow frame, this allows the screen of the machine to increase while the size of the entire fuselage is better controlled. The performance of the grip is worthy of recognition.

The chin has a brand new design

　　　　It is worth mentioning that HuaweiAscend P7The design of the "chin" has undergone some changes. Compared with the previous two-stage design, the design of the machine looks more coordinated, and the entire front is covered by glass, which also adds a bit of texture. Of course, HuaweiAscend P7The bottom part still stands out, which is also to reflect the design of its border.

　　　　Huawei Ascend P7The back of the Ascend P6 can be said to be very different from the previous stainless steel brushed backplane. HuaweiAscend P7Adopting a brand-new glass backplane design, and using the same Corning Gorilla third-generation glass as the screen, the use of front and rear double gorilla glass not only guarantees the scratch resistance of the front and rear, but also guarantees the strength of the whole machine.

The back of the fuselage also uses Corning’s third-generation gorilla glass.

The speaker is placed in the lower left corner of the fuselage

　　　　In terms of details, HuaweiAscend P7The upper left corner of the back is a 13 million pixel camera, the bottom is equipped with an LED flash, and the middle position is Huawei’s logo, the same as the front panel design, HuaweiAscend P7The two-stage design of the back panel has also been cancelled, and the speaker has also been placed at the lower left of the back, forming a vertical strip.

The earphone hole is designed above the fuselage.

Detail design of the bottom of the fuselage

There is no button on the left side of the fuselage.

The button sockets, etc. are all concentrated on the right side of the fuselage

　　　　HuaweiAscend P7The frame design of the fuselage is almost the same as that of the Ascend P6. Both models use a double C chamfer design, which adds a lot to the design of the whole model. The whole frame is designed with metal brushed wire, and both sides have chamfer design. The metal texture is very prominent, and the visual effect has also been improved a lot. It is worth mentioning that HuaweiAscend P7There are certain "edge" designs on both sides of the bottom to make the front of the fuselage look less "hard".

　　　　HuaweiAscend P7There was no interface or function on the left side of the fuselage. The previously controversial headphone jack was transferred to the top of the fuselage, and the design of the dust cover was cancelled. There was also a noise-canceling microphone next to it.

SIM card slot and microSD card slot

The design of the power button is very unique.

　　　　HuaweiAscend P7Most of the keys and sockets are concentrated on the right side of the fuselage. The top two keys are the volume key and the power key. In addition to the concentric circle design of the keycap, the power key also has a certain depression below, which makes the finger feel better and adds a certain visual effect. The following positions are the SIM card slot and the microSD card slot. Both card slots have text prompts for their positions, and it can also be seen that the model in my hand supports TD-SCDMA and LTE networks. It is reported that HuaweiAscend P7It will use a chip that supports 5-mode 10-frequency. The mobile version of Huawei in my handAscend P7It is a single-card design, while other versions use a dual-card version, and support TD-LTE and FDD-LTE dual 4G networks. In terms of battery life, HuaweiAscend P7A 2500 mAh battery will be used.

　　　　In terms of systems,Huawei Ascend P7Using Huawei’s latest Emotion UI 2.3, which is also its debut, the UI is based on the Android 4.4 version of the system deep customization, such a new Android version in the custom UI is indeed very rare, after the author’s experience, found that the new Emotion UI in the entire user experience has been more improved, the details of the portrayal is more refined.

　　　　We can see that when adjusting the camera to the front, select the skin beauty mode to perform automatic beauty. The processed effect can be intuitively displayed during the viewfinder preview, and the skin beauty level can also be adjusted at the bottom. In the panoramic selfie mode, the user can rotatecell phoneTo capture a wider angle of scenery and synthesize it, so that the entire photo can accommodate more people to take selfies together, this function is indeed very practical.

　　
Level 5 skin beauty sample display

　　　　Through several sample comparisons, it is not difficult to see that HuaweiAscend P7The skin beauty effect is still very obvious. Generally, the skin beauty effect is very significant when adjusted to level 5. Whether it is dermabrasion, sharp chin or big eyes, you can give you what you want, and even after taking pictures, the machine still has built-in post-beautification options. Users can adjust the picture and effect more freely. The author reminds netizens at the end that because the 6 million pixel photo is 16:9 mode, HuaweiAscend P7The default front-facing camera pixels are 6 million pixels. If you want more delicate image quality, users can adjust it to the 8 million pixel option.

　　　　Huawei Ascend P7In addition to the excellent performance of the front-facing camera, the strength of the main camera is also not to be underestimated. In terms of hardware, the pixel of this camera has reached 13 million, equipped with LED flash, and adopts F2.0 super aperture.SonyThe combination of the second-generation stacked sensor (not surprisingly, the model should be the IMX214) and the image ISP has enhanced the machine’s capabilities.

What did Feng Timo, who was off the air for half a year, do? On the evening of the 24th, she responded for the first time in an interview with the short video blogger @Dabaishow that she was suffering from advanced thyroid cancer and had undergone surgery.

On the show, the host asked her why she had been off the air for half a year. Feng Timo said: "There is something wrong with my health. I have a type of cancer, which is malignant and terminal thyroid cancer." The host was also very surprised and could not believe it. Then Feng Timo said that not only fans did not know, but also her parents did not know. When she learned that she was sick, she was a little confused at the time. Before treatment, she also asked the doctor if she could still sing in the future. The doctor said, "Don’t think about singing."

Although frustrated, Ms. Feng was encouraged by the experience of a patient who had a successful surgery. In the show, she also faced the camera and showed a scar on her neck from the operation. After the surgery, her voice was hoarse and she did not want to live for a while. Fortunately, after persistent training, she recovered her voice.

On the evening of the 24th, Feng Timo responded on his personal social media that he had indeed been diagnosed with thyroid cancer before, had undergone surgery, and was very successful. Now his body has recovered, and his throat has almost recovered under unremitting training. Through this cancer, she wants to tell everyone, especially girls, that they must not have mental internal friction, do not accumulate negative energy in their hearts, communicate more with family and friends, and be brave enough to speak out and take up legal weapons to protect themselves when they encounter online violence and pornographic rumors.

According to Life Times, the incidence of thyroid cancer is high, but the "personality" is mild, resulting in a low mortality rate. Between 1950 and 2004 in the United States, the incidence of thyroid cancer showed a significant increase, but the mortality rate actually decreased by 44%. Among thyroid cancers, papillary thyroid cancer is the most common, accounting for about 80%. Timely treatment has a good prognosis, and the 10-year survival rate can reach more than 90%.

Feng Timo, whose real name is Feng Yanan, was born in Wanzhou District, Chongqing on December 19, 1991. She is a Chinese mainland female singer and a live streaming host. She debuted from a live broadcast platform, and later attracted the attention of netizens because of her sweet singing. She once became the first sister of the platform live broadcast and participated in many variety shows.

　　Not long ago, Tsinghua University’s research team released an invention of "Smart Graphene artificial larynx", which makes use of the advantages of porous graphene materials to create an integrated acoustic device that is transceivable and wearable, and is expected to solve the "speaking" problem of deaf people in the future.

　　Internationally, researchers from institutions such as Cambridge University reported that they found a new way to "awaken" the superconductivity of graphene, and the awakened graphene can be used to manufacture supercomputers.

　　Graphene is the hottest new material at present. In the aviation field, people use "rare elements" to describe materials that are as light as air and as hard as steel. Previously, titanium alloy was considered as the ideal choice closest to this quality, while "rising star" graphene was considered as a step closer to the "rare element" of human dreams.

　　What is graphene?

　　At present, the thinnest, lightest and strongest material in the world is 100 times harder than the strongest steel.

　　Like diamond, graphite is a form of carbon. The difference is that, due to the different atomic structures, diamond is the hardest thing on earth, while graphite is one of the softest minerals, which are often made into graphite rods and pencil lead. Graphene is stripped from graphite material and only consists of a layer of carbon atoms on the plane.

　　It can be said that one of the characteristics of graphene is its thinnest material in the world, which is only one atom thick, about 0.3 nanometer, which is one-hundredth of the thickness of A4 paper and one-fifth of the thickness of hair. At the same time, it can conduct electricity, and the movement speed of electrons in graphene reaches 1000 km/s, which is 1/300 of the speed of light. Thin, strong, conductive and thermal … … These characteristics of graphene give people a lot of imagination.

　　Dr. Kong Yuechan, deputy director of the Key Laboratory of Microwave and Millimeter Wave Monolithic Integration and Modular Circuits of China Electric Power Department, said that the hardness of graphene is very strong, 100 times stronger than the strongest steel now; Graphene’s electron running speed is also very high, 10 times that of silicon, which is very suitable for developing the next generation of UHF electronic devices. In addition, graphene is also a master of heat conduction, which is 10 times stronger than the most thermally conductive metal silver.

　　The characteristics of graphene are also very "fun". For example, when a drop of water rolls on the surface of graphene, graphene can keenly "perceive" subtle movements and generate continuous current. This characteristic provides scientists with a new idea to obtain electric energy from the flow of water.

　　"Graphene can sense a single electron, and the movement of charged particles on the surface of graphene can cause the electrons in graphene to move rapidly, realizing the sensing and power generation process." Lin Shisheng, an associate professor at the School of Information and Electronic Engineering of Zhejiang University, said that this feature of graphene can be used in many applications in energy and electronic sensing, such as using an umbrella coated with graphene to generate electricity in rainy days, or making it into a sensitive sensing device.

　　It is these comprehensive properties that make graphene attract unprecedented attention, and some people even begin to predict that the appearance of graphene will lead an industrial revolution triggered by material progress.

　　How to obtain graphene

　　For the first time in the world, a single layer of graphene was obtained by "sticking" it with transparent glue.

　　The first time people got graphene, they used a "simple and rude" method.

　　Graphene itself exists in nature. Graphene is a thin layer of carbon atoms, and a hexagonal ring is formed between the atoms, and the rings are connected to form a honeycomb plane. It is graphite when stacked layer by layer, and graphite with a thickness of 1 mm contains about 3 million layers of graphene. Pencil lightly across the paper, leaving traces that may be several to dozens of layers of graphene. Previously, this two-dimensional structure of carbon has always existed in people’s conjecture, but it is difficult to peel off the single-layer structure. The key problem is how to stratify graphite into extremely thin slices.

　　Many people also had this experience when they were students. When they wrote typos on paper, they would use transparent tape to stick the typos off. But no one thought that it was such a simple method that people discovered the mysterious graphene.

　　To make graphene, simply speaking, it is necessary to thin graphite, not by cutting, not by grinding, but by sticking. In 2004, Heim and Novoselov of the University of Manchester in the United Kingdom repeatedly stuck and tore a graphite sheet with transparent adhesive, and the thickness of the graphite sheet gradually decreased, eventually forming graphene with a thickness of only 0.335 nm, that is, graphene with an atomic thickness. This is the first time in the world to get a single layer of graphene, so two scientists won the 2010 Nobel Prize in Physics.

　　Dr. Wu Yun, a senior engineer in the Key Laboratory of Microwave and Millimeter Wave Monolithic Integration and Modular Circuits of 55 China Electric Power Institute, gave a demonstration to the reporter. He stuck a small piece of graphite on the tape and then tore it overlapping. After sticking for half an hour, the tape was covered with gray graphite, and then the graphite was transferred to a clean silicon wafer with tape.

　　Wu Yun said, what we saw at this time was not graphene, because graphene is not only very thin, but also has a light transmittance of over 97%, which is almost completely transparent, and people can’t see it at all. To find it, we have to use special technical means. But this is already a multi-layer graphite sheet, and then the number of layers can be located and determined by technical means, and finally the single-layer graphene can be found.

　　Experts say that this is just the initial method of producing graphene. The mechanical stripping method, which evolved from the adhesive tape paper sticking method, is just a method for preparing graphene in the laboratory. At present, with the technological progress, high-quality graphene can be produced more.

　　What will graphene bring?

　　Using graphene material, the screen of mobile phone can be easily bent or even folded.

　　The appearance of graphene is expected to bring surprises to our lives. Mobile phone charging can be "second charging", mobile phone screen can be easily bent or even folded, and cars can use graphene static conductive tires to avoid deflagration caused by friction electrification … … From aerospace and electronic information to energy conservation and environmental protection, great changes are likely to take place in many fields by using the characteristics of graphene.

　　Using graphene instead of silicon can improve the performance of electronic chips. Researchers are currently introducing the production and application of graphene into the semiconductor industry, and the technological revolution triggered by graphene is likely to start with our common small chips.

　　The basic material of electronic chips is silicon. However, with the increasing density of components on the chip, the distance between the two components on the top chip is less than 10 nanometers, almost reaching the limit of silicon materials. What should I do if I want to continue to improve my performance? Researchers began to try to partially replace the role of silicon with graphene.

　　"Devices made of graphene can theoretically reach ten times or even hundreds of times the frequency of silicon, which can be applied to radar and greatly improve the resolution of radar. Moreover, it is widely used in communication and imaging. " Kong Yuechan said, moreover, the current R&D and production equipment of graphene is the same as that of ordinary semiconductor equipment, and the existing technology development can be based on mature equipment and processes, laying the foundation for subsequent engineering development.

　　Researchers are still doing another big thing. They attached graphene to a gold foil with a thickness of only 50 nanometers, and then used a new method to completely transfer graphene to a soft plastic sheet.

　　Kong Yuechan said that graphene can be transferred to any substrate that researchers want through flexible methods, such as a special plastic substrate for electronic devices, which is flexible and suitable for the preparation process of transistors. Through the special graphene transfer technology, the gold foil with graphene is attached to the plastic sheet, and based on this, electronic devices with certain functions are prepared on this plastic sheet. Most importantly, such electronic devices can be easily bent. In the future, whether it is a foldable display screen or a wearable device that can be implanted into the human body, it may be realized by such graphene devices.

　　Another highly anticipated application field of graphene is the storage of electric energy. In Tianjin Electric Power Research Institute, researchers here are conducting research on the most advanced capacitors. Capacitors, like batteries, can be used to store electric energy. Its advantage lies in its fast charging speed, which can be fully charged in a few minutes and can be reused for tens of thousands of times. But it doesn’t store as much electricity as a battery, and it can’t be used in life by storing enough electricity.

　　"This is the slurry made of modified graphene. Next, we will apply these slurries to aluminum foil through a coater and become the positive electrode for our graphene capacitor." Dr. Ding Fei, executive deputy director of 18 National Defense Science and Technology Key Laboratories of Chemical and Physical Power Technology in China Electric Power Department, said that capacitor materials have a vital impact on the performance of capacitors. Through the further modification of graphene materials, researchers are making the storage capacity of capacitors closer to the battery step by step, and at the same time, its ultra-fast charging speed can bring more convenience to people’s lives. "The modified graphene capacitor we are making can be fully charged in a few minutes, and its energy density is expected to be close to that of existing lithium batteries after a period of time."

　　Energy density refers to the amount of energy stored in a substance with a certain space or mass. The higher the energy density, the stronger the power storage capacity of this substance. According to Ding Fei, the energy density of the modified graphene capacitor they have developed has reached more than three times that of the traditional capacitor. Although it is still in the laboratory research stage, the powerful capabilities of graphene materials have enabled the R&D team to see the broad prospects for the application of modified graphene capacitors.

　　In the future, when the charging facilities are becoming more and more perfect, it may take two or three minutes for electric vehicles to fully charge with graphene batteries.

　　Gao Tao, director of No.55 Institute of China Electric Power Department and director of the Key Laboratory of Microwave and Millimeter Wave Monolithic Integration and Modular Circuits, believes that even under laboratory conditions, the magical properties of graphene have not been fully released. At the same time, there are still many challenges at the technical level, and there is still a long way to go for real large-scale application. However, by strengthening the combination of demand and research, important breakthroughs have been made in the preparation of graphene materials and device development. Graphene, a new generation of strategic emerging materials, will greatly change people’s lives.
