万有引力常数

By the end of 1999, the international committee CODATA, decided to officially increase the uncertainty of the accepted value for the gravitational constant from 128 ppm to 1500 ppm.

在1999年底，国际委员会 CODATA 决定正式把万有引力常数 G 的误差范围由0.0128%提高到0.15%。

They have been recorded by nature in several ways, which we can now interpret and use to find out the constraints of the variation of the gravitational constant over a long period of time.

自然界已经用好几种我们现在已经能够了解的方式记录下了这种变化，而且我们可以据此寻找很久以来万有引力常数变化的约束条件。

The natural relationship of Gravitational Constant is also concluded:, In which from definition of must basic unit of current intensityor coulomb in classical physics, the measuring principle of unit charge and the gas kinetics are combined, and the formula of relative theory of mass is used, by the use of the methods of logical inference with concludiung synthesis.

运用逻辑推理和归纳综合相结合的方法，从经典物理学的源头--电流强度单位的定义和电量单位的定义出发，结合元电荷测定原理、气体分子动理论以及相对论质量公式，导出了万有引力常量G的关系式：，解释了G的测量值的大小、变化及其范围，消减了一个物理基本常数。

Dividing this value by the gravitational constant, g , where g=9.81 m/sec 2 , gives the conventional units of "seconds".

除以这个值由万有引力常数，克，克= 9.81米/秒2 ，给传统的单位"秒"。

Kepler's laws of Newton discovered the law of gravitation 10000 l ^ D has laid the foundation, then to the law of gravity, in turn, amended the third Kepler principle, namely, the ratio of 32 to strictly say no is a constant with the planets related to the quality of the l ^ D.

开普勒定律为牛顿发现万l^D有引力定律奠定了基础，而后，万有引力定律反过来又修正了开普勒第三定律，即比值32严格说不为常数而与行星l^D的质量有关。

Why does the field force is in inverse proportion to the square of the distance between the two masses, but not to three or four power of ones and to prefigure that the constant G of the gravitation isn't invariant.

概述：此文章描述了引力的动力过程，阐述了引力质量是惯性质量的一种表现形式；场力为什么与作用距离的平方成反比，而不是与三次方、四次方成反比；并预示了万有引力常数G并不是真正不变的常量等等。

The gravitational mass is an embodiment of the inertial ones. Why does the field force is in inverse proportion to the square of the distance between the two masses, but not to three or four power of ones and to prefigure that the constant G of the gravitation isn't invariant.

概述：此文章描述了引力的动力过程，阐述了引力质量是惯性质量的一种表现形式；场力为什么与作用距离的平方成反比，而不是与三次方、四次方成反比；并预示了万有引力常数G并不是真正不变的常量等等。

Precise measurement of the Newtonian gravitational constant G plays important roles in the fields of the gravitation, geophysics, astrophysics, and cosmology. A torsion balance with timeof-swing method to determine the gravitational constant G is proposed.

Torsion balance ；万有引力常数G的精确测量不仅对于弄清引力相互作用的性质非常重要，而且对于整个理论物理学、地球物理学、天文学和宇宙学等都具有重要意义。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
