查询词典 celestial

See [90]. The theoretical work by these mathematicians supplied many of the ideas and approaches that were later used in more applied situations in physics, celestial mechanics, chemistry, biology, and other fields.

这些数学家的理论工作提供了很多思想和方法，这些后来都被应用于物理、天体力学、化学、生物学和其它领域更为复杂的情形。

The study of the mathematical model for such motion is called celestial mechanics , and involves a finite number of bodies moving under the effects of gravitational attraction given by the Newtonian laws.

对于这种运动的数学模型的研究称作天体力学，包括研究在牛顿万有引力定律作用下的有限个天体的运动。

Celestial mechanics: numerical method, N-body simulation; planetary systems: Solar System

天体力学：数值算法，N体模拟；行星系统：太阳系

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。

His research on mechanics deals with elastic mechanics, photo-elasticity, structural mechanics, visco-elastic mechanics, celestial mechanics, fluid mechanics, and dynamic stability.

他在应用力学方面的研究涉及到弹性力学、光弹性、结构力学、粘弹性力学、天体力学、流体力学、动力稳定性等方面。

Furthermore the laws of celestial mechanics www.readinggroupguides.com/ credited to Copernicus, Kepler and Galileo were know by the Chinese and used to create a very accurate calender in 1280 for Kublai Khan (page 23 -28) that was later adopted by the Europeans.

此外天体力学定律 www.readinggroupguides.com/贷记哥白尼，开普勒和伽利略系统是由中国的了解和用于创建一个非常准确的在1280年忽必烈汗（页日历23 -28），后来由欧洲人通过。

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。

Birkhoff, Siegel, Kolmogorov, Arnold, Moser, Herman, and many others investigated the ideas of stability and found complicated behavior for systems arising in celestial mechanics and other such physical systems, which could be described by what are called Hamiltonian differential equations .

Birkhoff ， Siegel ， Kolmogorov ， Arnold ， Moser ， Herman 和其他很多研究者研究稳定性的思想，发现了具有复杂行为的系统出现在天体力学和其它相似的物理系统中，这些都可以用称为 Hamilton 微分方程来描述。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
