电子管计算机的研制
中国计算机的研制起步于20世纪50年代。与国外计算机发展历程相同，国内计算机的发展也经历了从早期的基于电子管、晶体管的第一代计算机，到基于中小规模集成电路的计算机，一直到基于超大规模集成电路的计算机的过程。相对于国际上计算机研制的状况，国内计算机研制起步较晚，但是经过科研人员的艰苦努力，直至目前，中国计算机在很多方向的研究走在世界前沿，且部分研究已达到国际领先水平。
中国计算机事业在开创阶段，以“先集中、后分散”，“先仿制、后创新”的方针，迅速制成中国第一代电子管计算机、第二代晶体管计算机。建立了一批科研院所，在一些高校设立了计算机专业，并且通过国产计算机的系列化，形成了初具规模、能够批量生产的计算机工业。
1952年在全国大学院系调整时，华罗庚在中国科学院数学研究所（简称中科院数学所）内建立了中国第一个电子计算机科研小组，由闵乃大、夏培肃、王传英组成，华罗庚邀请闵乃大担任组长，开始了计算技术的探索。同年3月，由闵乃大执笔写出了中国第一个“电子计算机研究的设想和规划”。中国计算机的发展从华罗庚建立的第一个计算机科研小组开始拉开了序幕。
1953年4月，计算机科研小组提出制造一台电子管串行计算机的设想，其规模与当时美国、英国刚完成不久的EDVAC和EDSAC相当。1953年12月，计算机小组工作分成了两部分：由夏培肃负责基本逻辑电路、运算器、控制器的设计，由吴几康负责存储器的设计。吴几康研制的宽带放大器，使微弱信号达到逻辑运算的电平，成功实现了存储功能。夏培肃完成了第一台电子计算机运算器和控制器的设计工作，同时编写了中国第一本电子计算机原理讲义。

chinese写作文
1.关于chinese（中文）的英语作文
If your visions of Beijing are centred around pods of Maoist revolutionaries in buttoned-down tunics performing t'ai chi in the Square, put them to rest: this city has embarked on a new-millennium roller-coaster and it's taking the rest of China with it.
The spinsterish Beijing of old is having a facelift and the cityscape is changing daily. Within the city, however, you'll still find some of China's most stunning sights: the Forbidden City, the Summer Palace, Temple of Heaven Park, the Lama Temple and the Great Wall, to name just a few.
2. chinese breakfast写一篇作文Breakfast is something we often ignore when talking about cuisine. Want to
find out what Chinese people eat for breakfast? Let's have a taste of Chinese
breakfasts from the south to the north.
Generally speaking, the typical Chinese breakfast varies from region to
region. Let's begin with the Cantonese-style breakfast-- Yam Cha, or Dim Sum
which are popular in Chinatowns around the world.
Yam cha, literally, drink tea, is what Guangdong and HK people in particular
do if they go out for breakfast in the early morning. But if a Cantonese friend
invites you out to yam cha, allow plenty of time to enjoy it since it's not to
be rushed. Usually, it is a great way to spend a Saturday or Sunday morning.
Dim sum are little snacks, usually steamed, deep fried, or boiled, and the
variety is enormous, hundreds of them, mostly savoury. Like ha gao, A steamed
wafer-thin rice-flour wrapping filled with baby shrimp or minced shrimp and some
minced meat. The skin of rice-flour is so translucent that the ingredients can
be clearly seen.

6.《chinese culture》作文China is a unified nation consisting of many different ethnic groups. Fifty-six different ethnic groups make up the great Chinese national family. Because the Han people accounts for more than niy percent of China's population, the remaining fifty-five groups are generally referred to as"ethnic minorities." Next to the majority Han, the Mongolian, Hui, Tibetan, and Uygur peoples prise the largest ethnic groups. Although China's ethnic minorities do not account for a large portion of the population, they are distributed over a vast area, residing in every corner of China. From north to south, China's ocean straits consist of the Bohai, Taiwan, Bashi, and Qiongzhou Straits. China possesses 20,000 kilometers of land border, plus 18,000 kilometers of coastline. Setting out from any point on China's border and making a plete circuit back to the starting point, the distance traveled would be equivalent to circling the globe at the equator.China is one of the countries with the greatest diversity of wildlife in the world. There are more than 6,266 species of vertebrates, 10 percent of the world's total. China is also one of the countries with the most abundant plant life in the world. There are more than 32,000 species of higher plants, and almost all the major plants that grow in the northern hemisphere's frigid, temperate and tropical zones are represented in China. After 50 years' planned and large-scale economic construction, China today is one of the major economic powers with the greatest potential of development in the world, and its people live a paratively well-off life as a whole. From 1953 to 2000, China had successfully pleted nine five-year plans and marked achievements had been made, laying a firm foundation for future economic development. Since the implementation of reform and opening-up in 1979, China's economy has grown at an unprecedentedly rapid speed. sxy0003真心为您解答~~~亲，如果你认可我的回答，请点击【采纳为满意回答】按钮~~手机提问者在客户端右上角评价点【满意】即可。

9.写一篇有关chinese new year的文章这有三篇一、Chinese New Year I like the Chinese new year better than any other festival. This is a time especially for rest and joy. I need not study. I wear good clothes and eat good food. I have a good time from morning till night. To be frank with you,I am as happy as a king. The Chinese new year lasts as long as fifteen days. It gives us more pleasure than we have imagined. After that we have to resume our normal work.二、Chinese New Year Chinese New Year starts with the New Moon on the first day of the new year and ends on the full moon 15 days later. The 15th day of the new year is called the Lantern Festival, which is celebrated at night with lantern displays and children carrying lanterns in a parade. The Chinese calendar is based on a bination of lunar and solar movements. The lunar cycle is about 29.5 days. In order to"catch up" with the solar calendar the Chinese insert an extra month once every few years(seven years out of a 19-yearcycle). This is the same as adding an extra day on leap year. This is why, according to the solar calendar, the Chinese New Year falls on a different date each year. New Year's Eve and New Year's Day are celebrated as a family affair, a time of reunion and thanksgiving. The celebration was traditionally highlighted with a religious ceremony given in honor of Heaven and Earth, the gods of the household and the family ancestors. The sacrifice to the ancestors, the most vital of all the rituals, united the living members with those who had passed away. Departed relatives are remembered with great respect because they were responsible for laying the foundations for the fortune and glory of the family. The presence of the ancestors is acknowledged on New Year's Eve with a dinner arranged for them at the family banquet table. The spirits of the ancestors, together with the living, celebrate the onset of the New Year as one great munity. The munal feast called"surrounding the stove" or weilu. It symbolizes family unity and honors the past and present generations.三、Chinese New Year Chinese New Year is the longest and most important celebration in the Chinese calendar. Chinese months are reckoned by the lunar calendar, with each month beginning on the darkest day. New Year festivities traditionally start on the first day of the month and continue until the fifteenth, when the moon is brightest. In China, people may take weeks of holiday from work to prepare for and celebrate the New Year.。
