我们详细介绍了地震学中的辐射传输。从著名的唯象方法的声波，理论，然后推广到弹性波，包括偏振和模式转换的治疗。本文的最后一部分给出了声学传递方程的第一性原理推导。输运理论的基本量，如比强度和平均自由程，然后严格定义的统计性质的介质和波场。讨论了该理论的一些应用。
We present a detailed introduction to radiative transfer in seismology. Starting from the well-known phenomenological approach for acoustic waves, the theory is then generalized to elastic waves, including the treatment of polarization and mode conversions. The last part of the paper presents a first-principle derivation of the acoustic transfer equation. The fundamental quantities of transport theory such as the specific intensity and the mean free path are then rigorously defined in terms of the statistical properties of the medium and wavefield. Some applications of the theory are discussed.
