本文介绍了孤立源引力辐射理论和辐射引力场中光线的传播特性。它提出了一个理论研究的产生，传播，反反应，和探测引力波从天体物理源。在回顾了牛顿近似中引力辐射的各种四极矩定律之后，我们展示了如何将后牛顿修正纳入源多极矩、无穷远处的辐射多极矩和反反应势中。我们进一步讨论了光在引力波发射源外的线性引力场中的传播。从引力透镜势的角度讨论了时间延迟、光的弯曲和移动源频移的影响。时间延迟结果应用于引力波探测过程的描述。
The paper gives an introduction to the gravitational radiation theory of isolated sources and to the propagation properties of light rays in radiative gravitational fields. It presents a theoretical study of the generation, propagation, back-reaction, and detection of gravitational waves from astrophysical sources. After reviewing the various quadrupole-moment laws for gravitational radiation in the Newtonian approximation, we show how to incorporate post-Newtonian corrections into the source multipole moments, the radiative multipole moments at infinity, and the back-reaction potentials. We further treat the light propagation in the linearized gravitational field outside a gravitational wave emitting source. The effects of time delay, bending of light, and moving source frequency shift are presented in terms of the gravitational lens potential. Time delay results are applied in the description of the procedure of the detection of gravitational waves.
