In winter vacation, I was read " teenager brief read Chinese history " series a series of books, right " science is precursory " of Zu Chong " " this one paragraphic be very interested, read have quite experience, benefit bandit is shallow.
寒假里，我阅读了《少年简读中国史》系列丛书，对《科学先驱“祖冲之”》这一章节很感兴趣，读完颇有感受，获益匪浅。
The Northern and Southern Dynasties of advance of the Kingdom of Wei is a culture the times that bright, science and technology develops, there is Zu Chong in scientific domain. The full marks that regards China as ancient time / science is precursory, zu Chong's lifetime studies science, his main contribution can be divided make tripartite range for calendar of maths, astronomy and machinery.
魏晋南北朝是一个文化灿烂、科技发达的时代，在科学领域有四海知名的祖冲之。作为中国古代的满分/科学先驱，祖冲之一生钻研自然科学，他的主要贡献可以分为数学、天文历法与机械制造三方面。
In mathematical respect, the largest contribution of Zu Chong is the computation of pair of circumferential rate π , of Zu Chong gave out not only the two marks form of circumferential rate, or with circumferential rate the value is calculated the first decimally hind the 7th scientist, in the mankind outstanding contribution was made on mathematical history.
在数学方面，祖冲之最大的贡献是对圆周率π的计算，祖冲之不仅给出了圆周率的两个分数形式，还是世界上第一位用圆周率值计算到小数点后第七位的科学家，在人类数学史上做出了卓越的贡献。
In astronomy calendar respect, of Zu Chong not only the existence that confirmed phenomenon of precession of the equinoxes, still putting forward ought to be 45 every years 11 months back down for a time, distinguished tropical year and star year. Introduce precession of the equinoxes the earliest calendar, put forward to measure noonday sun shadow to grow the method that cuts with until a long time with an ancient Chinese sundial consisting of an elongated dial and one or two gnomons.
在天文历法方面，祖冲之不但证实了岁差现象的存在，还提出了应当是每四十五年十一个月后退一度，区分了回归年和恒星年。最早将岁差引进历法，提出了用圭表测量正午太阳影长以及至多时刻的方法。
Besides the achievement that calculates domain respect in all previous of maths, astronomy, still had made a kind of accurate machine of Zu Chong, if make an ancient Chinese vehicle with a wooden figure always pointing to the south afresh, construction is exquisite, movement is quick, direction is accurate; Reform water-powered trip-hammer is ground, turn water and water mill union rises, manufacturing efficiency rose greatly; The rate of boat of a thousand li of the design is very rapid.
除了在数学、天文历算领域方面的成就，祖冲之还制造过一种精密机械，如重新制造指南车，构造精巧，运转灵活，方向准确；改良水碓磨，把水推和水磨结合起来，生产效率大大提高了；设计的千里船速度很快。
Of Zu Chong calculate in all previous of maths, astronomy, science and technology, make those who wait for a lot of domain develop innovation, the culture bequest with since precious the Chinese nation, also be the success of science and technology with remarkable society of human ancient time. From this the science and technology that I associate to China is developing at full speed all the time: Go up to the sky from the first orbiter
祖冲之在数学、天文历算、科技、制造等诸多领域的开拓创新，既是中华民族宝贵的文化遗产，也是人类古代社会杰出的科技成就。由此我联想到中国的科技一直在飞速发展：从第一颗人造卫星上天
Erupt to the first atom bomb; Arrive from Telstar and the God of exploration satellite the Jade Hare-the moon enter the space; The marine world that explores 10 thousand meters sheep from go into business of flood dragon dragon, the high speed railroad to 350 kilometers speed per hour... the historical record that divine boat created low temperature of Chinese carrier rocket 4 numbers to blast off, divine boat sends aerospace 5 numbers Chinese spacefarer first, divine boat realized the flight task of much person much day 6 numbers, divine boat finished Chinese spaceflight 7 numbers first aerospace walks, heavenly palace with divine boat one number 8 butt joints succeed, built the lab between the first aerospace of Chinese...
到第一颗原子弹爆发；从通讯卫星和探测卫星的上天到玉兔升空；从蛟龙下海探测万米之羊的海底世界，到350公里时速的高速铁路……神舟四号创造了中国运载火箭低温发射的历史记录，神舟五号首次将中国航天员送入太空，神舟六号实现了多人多天的飞行任务，神舟七号完成了中国航天首次太空行走，天宫一号和神舟八号对接成功，建成了中国第一个太空间实验室……
From ancient up to now, chinese science and technology is in all the time fly, be like a bright phearl of a bright, yi Yi is unripe brightness, the times feeling in my heart is proud. "The boy is strong a country is strong " , as the teenager of the motherland, develop what should carry on Zu Chong not only ceaselessly, diligent at the spirit that study, learn hard even, ceaseless enterprising, grown the prosperity that is the motherland is prosperous and strong a force that contributes oneself.
从古至今，中国的科技一直在腾飞，如一颗颗璀璨的明珠，熠熠生辉，我心中倍感自豪。“少年强则国强”，做为祖国的少年，不仅要发扬祖冲之不断开拓、勤于钻研的精神，还要努力学习，不断进取，长大为祖国的繁荣富强贡献自己的一份力量。(文/张兆琪)
