- 引力波--引力辐射概念基础述评
- Gravitational Waves - A Review on the Conceptual Foundations of Gravitational Radiation
摘要：
本文在爱因斯坦的广义相对论的框架下，对引力波的理论基础进行了综述。在爱因斯坦早期工作的基础上，我们首先导出了线性化的爱因斯坦场方程，并计算出相应的引力波方程。此外，我们给出了从松弛的爱因斯坦场方程得到的远波区场点近似下的引力势。最后，我们仔细研究引力$n$体系统的辐射损失，并介绍了目前的干涉引力波探测器的一些方面。每一节都有一个单独的附录，其中显示了进一步的计算细节。最后，我们总结了主要的结果，并提出了一个简短的展望，目前正在进行的努力，建立一个空间为基础的引力波天文台。
英文摘要：
In this manuscript we review the theoretical foundations of gravitational waves in the framework of Albert Einstein's theory of general relativity. Following Einstein's early efforts we first derive the linearised Einstein field equations and work out the corresponding gravitational wave equation. Moreover we present the gravitational potentials in the far away wave zone field point approximation obtained from the relaxed Einstein field equations. We close this review by taking a closer look on the radiative losses of gravitating $n$-body systems and present some aspects of the current interferometric gravitational waves detectors. Each section posses a separate appendix-contribution where further computational details are displayed. To conclude we summarize the main results and present a brief outlook in terms of current ongoing efforts to build a spaced based gravitational wave observatory.
