The growth of these structures was initially driven only by the attractive force of gravity, but then later there was competition with the repulsive force of dark energy.

这些宇宙空间中的结构最初是由于万有引力的作用开始进化的，但不久之后就有暗能量的反重力作用与其对抗。

Gravitational constant , Planck constant , speed of light constant , Boltzmann constant , Avogadro constant , also to predict two undiscovered physical constants whose physical dimensions are C kg^-1 and K A^-1 respectively

The boon space Si say:Newton established astronomy because of discovering gravitational theory, because of carry on light of resolve but established the optics of science, established mathematics of science because of establishing binomial equation axioms and infinite theories, established the mechanics of science because of knowing the man's natural character of the mechanics.

恩格斯说：牛顿由于发现了万有引力定律而创立了天文学，由于进行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，由于认识了力学的本性而创立了科学的力学。

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"。

A Bohr atom is a solar system in miniature, with electrical forces taking the place of gravitational forces.

玻尔的原子模型是太阳系的缩影，不过以电力替代万有引力。

C* is related to the Specific Impulse by the Thrust Coefficient, C F , and gravitational constant, g ,.

c *是涉及到具体的冲动，由推力系数， c 女，和万有引力常数，克，。

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。

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 create nice smooth-looking visualizations, therefore, we often need to develop clever ways of limiting factors within the system (having a maximum velocity, a minimum distance, etc.).

为了在代码中实现万有引力，我们需要准备另一个函数，当把另一个物体作为参数传入的时候，就能计算出它所产生的万有引力。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
