引力中心

认为各种各样的射电源形态的出现可能是存在横向风和次引力中心的结果。

We imagined that a variety of radio sources morphology are the result due to the transversal wind and the sub-gravity force .

再看这条，万有引力的中心是什么？

And this one : What is the center of gravity ?

类比质心和引力作用中心，引入感应电荷中心和静电引力作用中心概念。

The concept about the center of inductive electric charge and the center of electrostatic force are introduced by analogy with the center of mass and the center of gravitation .

引力波的存在问题一直是引力论的中心问题之一。

The existence of gravitational-wave has been one of the central theses of the gravitational theory .

黑洞最主要的影响就是其巨大的引力作用使包括光线在内的一切物质被吸引到起中心，而这巨大的引力也在这中心附近造成了时空的扭曲，也就是所谓的相对论。

In many ways a black hole acts like an ideal black body , as it reflects no light . The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole .

提出了径向自引力不稳定扰动作为一种能源机制。本文还得到吸积盘自引力与中心天体引力量级比较的两个判据，并由此得到大质量黑洞吸积盘外半径的近似解析估计。

This paper has got two criterions for the comparison between the accretion disc self-gravity and the gravity of the central black holes , from which an analytic estimation for the outer radius of the accretion discs has been derived .
