广义相对论之守恒定律与重力波辐射

本文证明爱因斯坦之广义相对论运动方程能演变成为物质守恒定律。虽然获得的重力场能量动量张量相等于Ｌａｎｄａｕ－Ｌｉｆｓｈｉｔｚ所得的．但演变过程之物理概念是不同的。除此之外，本文分别从物体运动方程和测地线方程着手，提供了两个寻找重力波辐射的方法。

The Conservation Law and the Radiation of General Relativity Lam

This paper presents the conservation law of Einstein's General Relativity,in whch the continuity equation of matter and gravitational field is implicitly derived from the equation of the motion of matter.Although the obtained energy-momentum tensor is the same as the Landau-Lifshitz pseudotensor, the physical and conceptual foundation are different.Two alternative methods to obtain the gravitational radiation are proposed in this paper as well.The radiation will be derived from the equation of the motion of matter and geodesic equation separately.
