The great English scientist Newton(1643~1727) published the book Mathematical Principles of Natural Philosophy in 1687. It sums up all his studies and brings forward the three fundamental laws of mechanics, the law of universal gravitation and the laws at celestial mechanics.

英国伟大科学家牛顿(1643~1727)在1687年版的《自然哲学的数学原理》一书总其大成，提出动力学的三个基本定律，万有引力定律，天体力学等。

At that time, however, nonlinear differential equations had no universal solutions and some problems of celestial mechanics were still required to be resolved.

而非线性微分方程没有普遍解法以及一些天体力学问题的未决，促使庞加莱在微分方程求解过程中引入定性思想，创立了常微分方程实域定性理论这一新分支，突破了原有的微分方程求解的思维束缚，是微分方程研究历史上的一次重大飞跃。

Based on the fundamental theory of celestial mechanics and the discussion of two body problem under the action of universal gravitation ,the general model which can be continuously used to calculate the apparent place of celestial body in the solar system was derived. Then ,for the specific celestial body ,the material simulating method and the precision verification was given ,and the reason why the error was caused was analyzed and the corresponding method was offered .

摘 要：基于天体力学的基本理论和对万有引力作用下二体问题的讨论，推导出太阳系天体视位置长期计算的一般模型，然后针对特定天体给出了具体的仿真方法和计算结果的精度检验，深入分析了误差的产生原因并提出了相应的改进办法。

This problem, which was certainly known to the ancients, became especially acute in the seventeenth century with the invention of celestial mechanics, which first gave philosophers a certain picture of a way the world might be: it might be a world whose future states were entirely determined by the past and the laws of nature (of which Newton's laws of motion and law of universal gravitation served as paradigms).

这个从很早就被知道的问题，在十七世纪之后变得尖锐起来，因为引力力学第一次给予了哲学家一个明确的世界图景：可能世界的未来事态完全可以被过去和自然律（Newton的运动律和万有引力定律是范例）所决定。
