查询词典 gravitational mass

Poisson's equation:In space where the source density is ρ, the Laplacian of a : potential U is 2 U = 4πρK, where is the operator del and K is a constant (gravitational constant in case of mass and gravitational potential).

泊松方程：在源密度为ρ的空间中，位场 U 的拉普拉斯算子为： U = 4πρK，。在米-千克其中为 del 算子，K 为常数(质量的万有引力常数和重力势)秒单位制中应去掉常数 4π。

The gravitational mass is an embodiment of the inertial ones.

人的每一步行动都在书写自己的历史。——吉鸿昌

Another point is that the future must be an explanation of the equivalence principle, means that we have to understand that the inertial mass and gravitational mass the same, what are the reasons!

还有一点就是将来必须对等效原理做出解释，意味着我们就要了解到惯性质量和引力质量相等的原因是什么！

The gravitational mass and the inertia mass are not equal in the microscopic quantum behavior.

在微观量子行为中引力质量和惯性质量并不相等。

Newton precisely measured the inertial mass of a great many objects (what it took to get them moving, as in getting a pendulum started) and their gravitational mass (how fast they fell to the Earth), to determine that the two forces were equal, if not equivalent, and could be canceled out when doing physics.

牛顿精确测量了很多物体的惯性质量（使物体运动的内在动力，就像钟摆开始往复的动力）和它们的引力质量（以多快的速度向地表坠落），以此来确定这两种力是均等的，如果不均等，在做物理学运算时可能就会互相抵消。

In this paper gravitational mass defect in static and spherically symmetric metric discussed by Ghose and Kumar is extended to the case of charged, static and spherically symmetric metric (Reissner-NordstrSm metric).

本文把Ghosc和Kumer在球对称、静态引力场(Schwarzchild度规)中讨论的引力质量亏损推广到荷电、静态、球对称场(Reissner-Nordstrm度规)中，并计算了亏损以后的质量M随初始质量M_0、荷质比α和半径r的各种变化曲线。

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。

According to the relationship between gravitational potential and electrostatic potential, as well as considering the physical meaning of the contrastive mass-to-electricity (mass per unit quantity of electricity) a definition of intensive electrostatic potential of the system (the electrostatic potential per unit mass) was proposed.

根据万有引力势与电势的关系式和系统的对比质电比的物理意义，定义了系统的强度电势－单位质量的电势。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
