The weather is getting hot. Zhang Ke is relaxed these days. Every morning, he runs to Tang Jing''s house for breakfast and goes to school together. It''s not too difficult to spend some time at school. He either stays at school for self-study at night or accompanies Tang Jing to study at home. There is no strict review plan.


    Near the last period of the college entrance examination, the tension before the college entrance examination has faded.


    At night, the heat of the day gradually dissipated. Zhang Ke''s classroom was on the fourth floor, sitting on the seat near the window, holding the latest issue of consumer electronics magazine T3 in his hand. He took a pencil to describe the latest Motorola mobile phone published in the magazine, and wrote messy words. The handwriting was very scribbled. Zhang Ke recognized it himself every two days, May not be able to recognize them all.


    He doesn''t have to work hard for the college entrance examination. He sits in the classroom and thinks about some problems, but he has no pressure.


    The atmosphere of the college entrance examination in the school is weak. Less than one third of the students go to the classroom to study at night. Even the students who study at night in the classroom are no longer so serious. During this period, no teachers will come to the class to see the class.


    After reading the book for a long time, Tang Jing was embarrassed to ask Zhang Ke to help her pinch her cervical spine in the classroom and stretch her body in a restrained manner. Looking back, she saw Zhang Ke depicting the pattern of Motorola''s mobile phone on white paper and took the magazine. Seeing that the magazine introduced that Motorola''s mobile phone was only 65g, she smacked her mouth, knocked her chin on the desk and whispered to Zhang Ke: "Can Jinhu produce such a lightweight mobile phone?"


    "Jinhu''s current technical conditions are not up to standard," Zhang Ke shook his head and said, "this mobile phone is not sold in China. If you like it, you go to Hong Kong and I''ll send you this mobile phone..."


    Less than one-third of the people sat in the classroom. Zhang Ke and Tang Jing occupied a corner, and no one came to bother them. Du Fei was still there when he studied at night. In the twinkling of an eye, he didn''t know where he had gone. Zhang Ke and Tang Jing talked casually in the corner, and didn''t worry about being heard and frightening others.


    "I don''t want this," Tang Jing shook her head. "I''ll use whatever mobile phone you can make. As long as you give it to me, that ugly mobile phone doesn''t matter..."


    "Don''t say that. People will be crazy if they hear it. That mobile phone may enter the museum in the future," Zhang Ke smiled. Tang Jing said that the prototype he played with the other day looked simple enough and similar to Motorola''s mobile phone, but it was not easy for ESS''s R & D team to take out the prototype in just one month, "When you say that, I feel a lot of pressure. You can''t lose your mobile phone."


    "Whatever!" Tang Jing smiled proudly after listening to Zhang Ke''s words. "Men need some pressure."


    "Come and help me see. There are three schemes here. Which one do you like?" Zhang Ke took down the front white paper on the folder. Below is a stack of mobile phone design schemes.


    The three product development centers in Seoul, Tokyo and Hong Kong have been running successively. Several white papers on the upper layer of the folder are painted, and the lower layer is the latest mobile phone design scheme taken out by the designers of the three centers.


    "Well, I said, why do you stay with me in the classroom all day?" Tang Jing turned the folder upside down, clenched her hand into a fist, pressed her chin on the fist hole, and looked at the mobile phone picture on the design draft. There were red pen comments written in the blank space next to the design draft. Tang Jing recognized Zhang Ke''s handwriting - Zhang Ke sometimes couldn''t understand what she wrote, and asked Tang Jing - Tang Jing saw Zhang Ke playing in the classroom all day Yi raised his eyes and asked him, "will it be very boring..."


    "No," Zhang Ke shook his head and said, "product design needs more spiritual thinking, which is very suitable for killing time..."


    Whether it is Lianxin, lianxun or Dongxing, these three companies have no technical preparation, and the OEM can only paste the second-class products of overseas mobile phone manufacturers. The whole set of mobile phone manufacturing technology obtained by Jinhu from Deyi is also second-class technology. The starting points of the said companies are the same.


    It takes time to make a breakthrough in technology. It may take two or three years to make a huge investment in technology research and development, so as to shorten the gap with overseas mobile phone manufacturers such as Nokia, Philips and Ericsson. However, second-class technology can not win the first-class market.


    Then we need to work on mobile phone design.


    Zhang Ke''s greatest role is to provide some forward-looking suggestions on mobile phone design.


    Generally speaking, when the mobile phone design industry is mature, the complete design cycle of mobile phone design and sample preparation is usually about 40 days. However, this is a product design implemented without departing from the existing technical conditions.


    Jinhu obtained only second-rate mobile phone manufacturing technology from Deyi. Some forward-looking suggestions made by Zhang Ke often exceed the existing technical conditions of Jinhu.


    Well, when Zhang Ke put forward these opinions, ESS''s R & D team members and the engineers of the product development center were busy for a while.


    Zhang Ke''s understatement. He wrote a simple sentence on the design draft: "the lens (display screen) needs to be widened in design" , this is not just about the readjustment of the mobile phone panel: widening the display screen will increase the power consumption without sacrificing other functions, and ensure the standby time, so the technical level of the power management chip needs to be improved; the widened display screen requires the upgrading of image processing technology, and even the STN LCD with more exquisite image display quality.


    Of course, it is undeniable that this is the biggest advantage of Jinhu.


    With Zhang Ke''s forward-looking suggestions, Jinhu''s technology R & D team can concentrate resources, grasp the key of the problem and lead the progress of technology without taking a tortuous road; However, the technology developed by general high-tech companies with great efforts has little real commercial value.


    Of course, for the first mobile phone issued by Jinhu under the brand of "idea", there are no other additional requirements except for the design of widened lens.


    "Mobile phone ringtones need to be louder and more pleasant. The use of chords requires the technical department to concentrate on attacking the level," Tang Jing quietly read a line of comments on the design draft, turned her head sideways, thought for a moment, but still found it difficult to understand, and asked Zhang Ke, "chords refer to polyphony. What''s difficult to achieve?"


    "Hehe, I just figured this out," Zhang Ke smiled proudly and deliberately showed off in front of Tang Jing, "No, you won''t think. In fact, the current mobile phone ringtones are very monotonous. Polyphony refers to the simultaneous pronunciation of multiple sound sources, which is like playing multiple musical instruments together, and the timbre will be fuller and rounder. When we listen to music with software on the computer, we can directly hear the effect of multiple performances from one channel; however, mobile phones can''t. the channels of mobile phone ringtones are single, so it''s difficult It''s like there''s only one musical instrument. I can''t get the effect of multiple performances. The current technical means can only increase the sound channel to simulate the polyphonic effect, and the effect sounds like a chord. As for how to realize it technically, it''s not my concern... "


    Tang Jing compared three mobile phone design schemes, looked at them for a long time and shook her head: "I''m not very satisfied. If you can reflect all the things you wrote next to the design draft, it seems worth looking forward to... Listen to you, it seems technically difficult..."


    "It shouldn''t be too big," Zhang Ke thought to himself. He didn''t put forward the concept of full touch screen smartphone, which will be popular only ten years later. The main reason is that Jinhu''s technology accumulation is not enough. Everything has just started, and the requirements can''t be too high. He said with a smile, "It''s difficult to double the screen width. First widen the size by a quarter; if it''s difficult to make a Septet chord ring tone, first realize the effect of a trio chord ring tone; if you want to make a single machine light and thin, it''s difficult to make it weigh only 65g, then make it 130g first... The improvement of technical level is always a gradual process. If the overall performance takes a big step forward, you can launch a new model product."


    Mobile phone screen and ringtone are the two details that Chinese people pay most attention to when buying mobile phones. Of course, Zhang Ke also put forward many cumbersome suggestions, which almost drove the design and technical team of Jinhu. It is said that Cheng Hanzhang''s laboratory in Silicon Valley has inherited the good tradition of sleeping in the laboratory when Ding Huai and Su Jindong developed DVD players in their early years. Although Lianxin announced that it would be launched before July For their first mobile phone product, Zhang Ke asked Chen Xinsheng and Su Jindong to take out their first mobile phone to shake the market.


    Jinhu has a perfect sales channel and after-sales service system, especially the mobile phone sales channel of Shengxin in East China can be directly used - Shengxin''s model was originally founded by Zhang Ke and finally helped Shengxin improve in East China - the experience of developing the market is also becoming more and more mature. In addition, the more fully prepared the production is, the more stable the quality of products can be guaranteed; Jinhu is not bad Two or three months, and I don''t compete with Lianxin for these two or three months.


    Tang Jing talked to Zhang Ke for a while, and then went to study again. Zhang Ke stopped thinking and felt a little bored. He looked up and didn''t see Du Fei in the classroom. He didn''t know where the boy went in the twinkling of an eye. He stuffed the folder under Tang Jing''s desk. He walked out of the classroom and called Du Fei in the corridor. The vibration of his mobile phone came out of the classroom The boy didn''t take his cell phone with him when he went out.


    Seeing Tang Jing sticking out her head in surprise, Zhang Ke pointed downstairs and motioned to go down. He strolled to the canteen, bought two cans of coke and was ready to go back to the classroom. He saw the shadow of the new student canteen that had not been opened, and someone took a flashlight to the entrance of the stairs.


    "Hehe, the people in the political and religious department ran to catch the traitor again..."


    Zhang Ke looked back, gave Du Fei a can of ice cola and asked him, "where''s your boy?"


    "Before the grandchildren of the political and religious office searched, I ran out and informed the wild mandarin ducks to flee the scene..." Du Fei said with a smile.


    "You''re really free..." Zhang Ke laughed. The headquarters of century Jinhu had moved to Jianye. Although Du Fei wanted to make up his mind to review carefully, he had to find something to eliminate the blame after review.


    In a strict sense, high school students'' love can not be regarded as early love, but the atmosphere of Haizhou No. 1 middle school is relatively strict. After all, the preferential treatment that Zhang Ke and Tang Jing can receive is very special. Most students are only forced to choose simple reading. However, at the last time, the repressed love seems to be accelerating maturity. Several pairs of lovers have emerged from Zhang Ke''s class, and the political and religious department From time to time, when the teachers study at night, they all go out to search the dark corners of the school.


    Zhang Ke didn''t take it seriously when he saw the teacher of the political and educational department entering the new canteen that had not been opened with a flashlight. He knew that even if he was caught by the political and educational department at this time, he would not be dealt with seriously. The school should first ensure that the mentality of senior three students before the examination is stable. On the contrary, the students of No. 1 middle school are afraid of the political and educational department, but they don''t have the relaxed mentality of Zhang Ke.


    "Dufei, dufei," a boy ran over and called dufei. Zhang Ke recognized that he was a classmate in the class. The girl wearing a water green dress behind him was also a classmate in the class. The boy''s name was Xiao Chunming. Zhang Ke didn''t remember the girl''s name. Xiao Chunming was in a panic just out of danger. He patted his chest and said, "It''s a close call. Li Ji and Xu Ruohong didn''t come out in the new canteen. Now they''re miserable. They''re going to be caught by the people of the political and religious department..."


    "Let''s go and have a look together. Maybe we can take advantage of the chaos and bring them out." Du Fei waved and walked towards the new canteen. Many students gathered here to watch the excitement. Du Fei waved and they all ran after him.


    Zhang Ke curled his lips. Unexpectedly, Du Fei''s appeal among the students of No. 1 middle school was quite good.


    In the past three years of high school, Zhang Ke has been in school all day. He can count the time by breaking his fingers. Naturally, his friendship with his classmates is very weak. Few students can name him.


    Although Du Fei sometimes gets involved in things outside the school, he wants to show himself as a good student in front of Li Zhifang and stays at school most of the time.


    Du Fei can''t compare with Zhang Ke and Sheng Qing, but in school, Du Fei is very mature - there are also factors to strengthen the ripening of Zhang Ke and Sheng Qing - Du Xiaoshan has been strict with him since he was a child. He has no disgusting habits. He treats people and things very well, and has great prestige among students. In addition, Du Fei has actively participated in the organization and taught students in the two winter camps sponsored by Jinhu The feeling of the school''s teaching staff is that Du Fei uses his Lao Tzu''s influence to benefit the school. If there were to be a democratic election to recommend the most popular students in the school, the student union would choose Du Fei, and the teaching staff would also choose Du Fei. This boy would have cleared away his evil deeds long ago, which is very different from Zhang Ke''s reputation.


    Zhang Ke followed; Du Fei had a flashlight in his hand and took a picture of the dark window of the new canteen. Suddenly, two people were attached to the windowsill on the second floor. Zhang Ke was startled. It seems that the two people planned to jump down from the second floor in order to avoid the teacher of the political and religious office.


    Although it is on the second floor, the bottom floor of the comprehensive canteen is a hall with a height of 56 meters. With the height of the windowsill, jumping from a height of 67 meters to the concrete floor, most of them can''t die, but fractures are inevitable. The windows on the second floor are not open, and the windowsill is very steep, so it''s difficult to drill back out of the window. Standing on the narrow windowsill, there is no window lattice to grasp, so I don''t pay any attention It''s possible to lose your hand and fall down; the risk of losing your hand and falling down is even greater.


    Zhang Ke hurriedly separated and was stunned. The crowd crowded to the front, but heard Du Fei standing in front and scolding: "Li Ji, what are you afraid of the turtle grandsons of the political and religious department? I broke Cao Guangming''s nose with a punch. I didn''t hear him hum. If you have seed, you and Xu Ruohong came out of the stairs for me..." The flashlight shone on the wall next to Li Ji, not directly on the people, so as not to panic them.


    Zhang Ke couldn''t think of anything more reassuring than Du Fei''s laughing and scolding. Du Fei was much more mature. When he saw a stack of abandoned empty sacks under the cement steps, he jumped over and hugged them. He threw a pile of empty sacks on the cement steps under the windowsill. The students on the side looked at it slowly and quickly looked for soft things to fill in.


    Zhang Ke grabbed Xiao Chunming and said to him, "find some people to help them climb back..." he climbed up the steps and stood side by side with Du Fei. He said to Du Fei, "you stare at Li Ji and I stare at the woman. If anyone falls down, rush to carry it, cushion them, and don''t let them land on their head first..."


    They can''t jump out of a big event with their feet down. If they miss their hands and head down, they don''t know what the sack can do. Rush to carry it, as long as it doesn''t happen. Fortunately, it''s only six or seven meters high, so the momentum and speed of falling won''t be too great.


    Xiao Chunming led three or four strong boys to rush up the stairs. Du Fei was also a little nervous. After listening to Zhang Ke''s words, his muscles collapsed. Who wants to have an accident with his classmates who have been together day and night for three years?
