查询词典 universal gravitation

Newton to humanity's contribution is huge, just like Engels said:"Newton as a result of invented law of universal gravitation to establish the science astronomy; As a result of has carried on the light decomposition, but established the science optics; As a result of established the binomial theorem and the infinite theory established the science mathematics; As a result of has known the strength essence, but established the science mechanics".

牛顿对人类的贡献是巨大的，正如恩格斯所说："牛顿由于发明了万有引力定律而创立了科学的天文学；由于进行了光的分解，而创立了科学的光学；由于创立了二项式定理和无限理论而创立了科学的数学；由于认识了力的本质，而创立了科学的力学"。

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。

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。

That means that the universal gravitation can not supply enough centripetal force.

这说明该向心力不可能是由万有引力提供的。

This paper which aims at the continual occurrence of the earthquake and existence of the universal gravitation and the tide phenomenon has established the special theory-- cosmography, which considers that earthquake research should study both geography and astronomy, exceeding the traditional idea bravely.

摘 要：本文针对地震的频繁发生，结合天地间存在的万有引力与潮汐现象，大胆突破传统观念，提出了独特的研究地震需结合天文地理的"天地学"。

The law of universal gravitation is that existence all interacts between any two objects gravitation.

万有引力定律是任何两个物体之间都存在相互作用的引力。

The Law of Universal Gravitation is employed to analyse the gravitation acted on the sea water on the earth.

从万有引力定律出发，分析了地球表面海水所受的引力作用，阐明了地球上海潮起因是太阳和月球的万有引力，其中月球引力起主要作用。

With the formula of universal gravitation and centripetal force, we can find out the centripetal force to keep two stars moving in a circle orbit is equal to 3.4 octillion times of the universal gravitation between the two stars.

利用万有引力和向心力的公式，我们可以计算出，绕转所需的向心力为万有引力的3400亿亿亿倍。

To be sure, that principle - universal gravitation - was something of a disappointment to the older cadre of mechanists, since mechanism originally sought to explain all phenomena entirely in terms of the motion and collision of material bodies, whereas Newton's principle of gravitation required action at a distance.

事实上，这一原理--万有引力--对于机械论者的旧有核心来说是令人失望的，因为机械论原本希望可以将一切现象完全解释为物质物体的运动和碰撞，而牛顿的引力原理则需要相隔一段距离的运动。

Do you know, i need you to come back

你知道吗，我需要你回来
