The seismic study of the Sun and other stars offers a unique window into the interior of these stars. Thanks to helioseismology, we know the structure of the Sun to admirable precision. In fact, our knowledge is good enough to use the Sun as a laboratory. We have also been able to study the dynamics of the Sun in great detail. Helioseismic data also allow us to probe the changes that take place in the Sun as solar activity waxes and wanes. The seismic study of stars other than the Sun is a fairly new endeavour, but we are making great strides in this field. In this review I discuss some of the techniques used in helioseismic analyses and the results obtained using those techniques. I focus on results obtained with global helioseismology, i.e., the study of the Sun using its normal modes of oscillation. I also briefly touch upon asteroseismology, the seismic study of stars other than the Sun, and discuss how seismic data of others stars are interpreted.

对太阳和其他恒星的地震研究为了解这些恒星的内部提供了一个独特的窗口。感谢日震学，我们对太阳的结构有了令人钦佩的精确度。事实上，我们的知识足以将太阳用作实验室。我们还能够详细研究太阳的动力学。日震数据还使我们能够探测随着太阳活动的盛衰而发生的太阳变化。对太阳以外恒星的地震研究是一项相当新的尝试，但我们在这一领域正在取得巨大进步。在这篇综述中，我讨论了日震分析中使用的一些技术以及使用这些技术获得的结果。我重点关注全球日震学所获得的结果，即利用太阳正常振荡模式对太阳进行的研究。我还简要介绍了星震学，即对太阳以外恒星的地震研究，并讨论了如何解释其他恒星的地震数据。
