Tell me about one of the latest tech personalities begged

China's chip is a hurdle that all Chinese IT elites can't overcome, but Deng Zhonghan has silently stepped through this hurdle. In 1999, Vimicro was established, and in July 2001, it launched "China's first chip" - "Starlight No. 1" chip for digital imaging, and successfully realized marketization and entered the international market. Of course, these are just the beginning of Deng Zhonghan and Zhongxingwei, after which Zhongxing Micro launched "Starlight No. 2", No. 3 and No. 4.

Of course, the significance of the digital image chip is not that it created the first Chinese core, but that it promoted the whole.

The digital industry is booming. Deng Zhonghan sees a huge business opportunity in the digital industry.

Although the imaging quality of domestic digital camera chips is still relatively low, it cannot be compared with high-end digital cameras with 3 million or even 5 million pixels, but the advantages caused by low cost have made Vimicro a success. 2003 is a year of rapid development of the digital imaging industry, in this year, digital cameras have been unprecedentedly popular, the popularization of equipment brings people not only to enjoy the fun of convenient photography, but also the popularity of the entire digital industry, the transformation of the traditional imaging giant Kodak to convey this message to people. Deng Zhonghan and his Zhongxingwei, in an unexpected field, secretly changed the "heart" for the digital camera, and overnight people found that the digital camera can also be less high, and the domestic chip has injected new impetus into the development of the domestic digital camera and imaging industry.

In 2003, another important move of Deng Zhonghan was to launch the "Digital China" project with Wu Ying, Ding Jian and others, with the aim of "promoting the digitalization process of the whole of China and Asia, and promoting the digital development of China and developed countries". Through the investment in digital chips, Deng Zhonghan wants to achieve his goal of "making Vimicro a leading enterprise in the field of digital imaging, and bringing China's digital imaging technology industry as a whole to the forefront of the world's digitalization". The next important target is the computer camera that can be used as a "network entrance", although it seems difficult to expand the market, but this is Vimicro's most long-term strategic development project.

Resume: He graduated from the University of California, Berkeley in 1997 and obtained a Ph.D. in electrical engineering, a master's degree in economic management, and a master's degree in physics. In 2000, he cooperated with Tsinghua University to establish Tsinghua Zhongxing Integrated Circuit R&D Center and served as the chairman.

In 1999, he founded Vimicro Company.

This guy is really good. You can use it. He has just been elected as one of the top ten economic figures of CCTV in 2005. Hot enough. Strong enough.

I once heard my grandfather say that as early as 100 years of history, society was an agrarian society that depended on the sky for food. At that time, there were no electric lights, no televisions, no cars, and they ate leaves and bark, even belts.

Now I hear my mother say that when she was a child, she went to self-study in the morning and evening, and everyone carried a kerosene lamp, not even a stationery box, she used a cardboard box as a stationery box, and she ate pickles every day, and only ate white flour steamed buns when she came to visit or celebrated her birthday. Crops are grown on the shoulders of men, and oxen and horses are used to plough the fields. Each child only adds one new dress a year, and the new clothes are not worn until the New Year, and adults do not even add one new dress a year.

In the eighties, the first four modernizations were proposed, and the land was covered in a large way. The living conditions of the people have been improved, and they have stopped eating the nest and eaten the white **, and lived in a new tile house.

In the twentieth century, food was nutritious, clothing was famous, peasants lived in high-rise buildings, and people in cities lived in villas and cars. Families in rural areas have also bought refrigerators, color TVs, washing machines, and every family has used mobile ** and driven motorcycles.

In the 21st century, China has landed on the moon, opened high-speed trains, ocean-going ships, etc., and now there are countless new technologies.

Looking at the past, Bibi now, we live in a very comfortable living environment and do not worry about spending money on food and clothing. We must study hard and serve the motherland when we grow up.

Thank you! ~~

Brother has also encountered this problem, to tell you the correct solution: if you go slowly, press the caps losk key on the left side of the keyboard, I hope you can find it, and then clearer, that is, press the second light in the upper right corner of the key and it will turn on. If the backpack exceeds the load, it will also walk very slowly, and finally, I hope to adopt

Of course, the pros outweigh the cons; The reason manifests itself in many ways: from medicine: all kinds of modern techniques.

Benefit!

(Our class is also going to have a debate).

I choose Lida! I believe that the level of scientific and technological development of human beings in a few years is beyond the imagination of all of us here, just like the human beings who were drilling wood to make fire in the Stone Age, they could not have imagined that our world now has gas and electricity. Mankind will not be ruined by science and technology, on the contrary, science will only make mankind more and more progressive.

The development of science and technology is unlimited. What the other party says, you use this sentence to refute him, column: car exhaust pollutes the environment, refute that the development of science and technology is infinite, because the development of science and technology is infinite, who said that you can't build a car that doesn't pollute in the future? (Digression....)

Why do people yawn.

Ishimuro Junior High School Class of 2015.

"From the beginning of life until the end of life, people yawn, especially when they are tired and tired. Why is that? To find out why, I consulted two of the family's elders—my father and my grandfather.

But Dad and Grandpa don't understand it either, maybe it's because of the needs of the human body! Probably the brain reminds itself that it's time to rest.

With such a vague answer, I don't stop there. So, I continued to look up materials in the library and on the Internet, and finally, I found the right answer: scientists have found that a person's yawn lasts about 6 seconds, during which time the person closes his eyes and listens, and the whole body feels comfortable.

Therefore, it can be considered that yawning gives a person the best relaxation physiologically and psychologically, and has an important physiological protective effect on the human body. I heard my grandfather say that yawning is a sign of lack of oxygen to the brain, but this is not the case. On the contrary, the human body increases oxygen in the blood through the deep breathing exercise of yawning, excreting more carbon dioxide, which makes the person more energetic.

We've all had that experience. When we feel sleepy, we always yawn and yawn. This is the brain reminding the human body that it is tired and needs to sleep and rest.

So, yawning is actually a hypnotic method. I don't know if you have noticed, but when we are about to enter the intense work, such as before an important exam, before a large-scale speech contest or a theatrical performance, we often yawn a lot. At this time, we may complain that we are not concentrating, not nervous enough, and not in a good state.

Don't worry, that's not a bad thing. At this time, our spirit is in a state of tension, yawning is the human body with the help of deep inhalation is to add more oxygen to the blood, improve the activity of the brain, so as to promote the cerebral cortex from the state of inhibition to the state of excitement, so that the cerebral cortex can work better. Based on this principle, I speculate:

If we are about to enter a stressful work, we can take a deep breath like yawning, which can help us relax and adjust our body to a better state.

See, as long as we discover and ask, there is so much knowledge hidden in a small yawn! I will study hard, and through continuous learning, I will gain more knowledge, so that I can discover more mysteries in the future.

What is the effect of vinegar on flowers.

Vinegar is a commonly used condiment in life, and flowers can purify the ecological environment and beautify our lives.

Have you ever wondered what vinegar has to do with flowers? We carried out this project with curiosity. According to people who are experienced in growing flowers, applying a vinegar solution to potted flowers can improve the growth of potted flowers, increase the number of flowers, and the flowers are lush and leafy.

This was quickly confirmed in our experiments.

Do vinegar solutions with different concentrations have different effects on flowers? This is our second phase of experimentation. We selected four pots of starry, primrose, and moon flowers with the same growth, and divided them into four groups, each group (three pots) had three kinds of flowers, which were numbered and labeled respectively.

At the same time, we take edible white vinegar and prepare three solutions with different concentrations of 1 (pH 01 (pH 0001 (pH 6), and spray one vinegar solution to the three groups of potted flowers every day, and the fourth group of potted flowers are sprayed with vinegar-free water. Observe and record the growth of flowers every five days.

The results of this experiment showed that spraying with a low concentration of vinegar (pH 6) had no significant effect on these flowers; Flowers sprayed with medium concentration of vinegar (pH 4) grew significantly better than the other groups, with more buds, earlier flowering period, and more intense flower color, and longer flowering period; After spraying a high concentration of vinegar with a pH of 2 3, the flowers withered prematurely.

Through this experiment, we can tell you: spraying some vinegar when planting flowers can make flowers grow better. However, it is necessary to control the concentration of vinegar, too much acetic acid will damage the flowers.

The growth of middle school students is inseparable from books, books are our spiritual food, without their nourishment, our life is imperfect; Without them, our lives are lacking; Without their fullness induction, our spirit is nothing. Reading, especially literary books, is like spring rain that feeds the earth and enriches our lives. Like the summer breeze cooling the world, let us enjoy life; Like autumn fruits hanging on the branches, so that we are full of energy, the mystery of literary masterpieces imperceptibly infects me, shapes me, and achieves me, "sending charcoal in the snow" is undoubtedly our real experience of literary masterpieces!

The four great masterpieces of our country can be described as broad and profound, and I also have a soft spot for them. "Journey to the West", when I was a child, I always felt that it was both enjoyable and interesting, and the bizarre and colorful mythological world made me nostalgic and forgetful, and the aftertaste was endless. But today, reading "Journey to the West" again, my understanding has changed.

"Journey to the West" is a wonderful flower in the hundred gardens of ancient literature in China. Since its inception, it has been popular, popular in the literary world, and the story has been circulated, widely spread to the people, and it is really a household name, known to women and children, and appreciated by both the elegant and the vulgar. Whenever I open "Journey to the West", I always have a different mood.

At this moment, I have a new understanding, and his twists and turns in the plot conceal the ideal of life and the pursuit of human nature that people yearn for but cannot reach, that is, freedom.

After a long period of restricted personality, people in the new century are particularly yearning for freedom and the embodiment of freedom: Monkey King. Sun Wukong broke out of the stone, "not under the jurisdiction of the unicorn, not subject to the phoenix, and not subject to the constraints of the throne in the world", broke into the Dragon Palace, made trouble in the underworld, and became the king on Huaguo Mountain.

It can be said that it has reached a state where human nature is free from all shackles and completely free. Sun Wukong is actually the embodiment of freedom, the most prominent of his qualities is the yearning for freedom, he has always pursued freedom, and all its struggles are also for freedom. Such a vivid image gives the reader the strength and courage to pursue freedom and pursue freedom.

However, everyone understands that complete freedom is not possible now, even in the future, and that man will always be bound in one way or another. Although we are surrounded by a constrained world, we can make our hearts as wide and deep as possible, so that it can be boundless and encompassing the world.

However, there are still many people in society who are bound by something of little value, but they are happy and satisfied. After hundreds of years of exploration and development, people's material needs are no longer urgent, but the need for spiritual freedom has been erased for no reason. In short, I think what modern people lack the most is a spirit of pioneering and seeking maximum freedom.

In "Journey to the West", which has been tempered with all its time, it deeply contains the ...... of the free spirit that people crave most in the new century
