标题： Gravitational Waves, Sources, and Detectors

摘要： 研究生在1999年在科莫湖举行的讲座笔记，涵盖了线性化引力波的理论、它们的来源，以及当时探测引力波的前景。 这些讲座由于教学原因仍然具有吸引力，特别是因为它们包含对电流四极引力辐射（与中子星的r模有关）的处理，而这种内容在其他资料中不易找到。 显示英文摘要

摘要： Notes of lectures for graduate students that were given at Lake Como in 1999, covering the theory of linearized gravitational waves, their sources, and the prospects at the time for detecting gravitational waves. The lectures remain of interest for pedagogical reasons, and in particular because they contain a treatment of current-quadrupole gravitational radiation (in connection with the r-modes of neutron stars) that is not readily available in other sources.
