摘要
界面是介质间的分界面，把界面看成是双侧的，只是真实界面模型表述的一个极端，在很多情况下，它的另一个极端，即单侧界面模型可能更近于实际．在单侧界面条件下弹性波的传播问题，与双侧界面问题相比，还是一个尚未充分研究的领域．
The interface is the separatrix between two media.It is only as an extreme in the model descriptions to be regarded as beingbilateral. There are many cases in which its another extreme, i.e., thesocalled unilateral model may possibly be more close to the reality.The propagation of elastic wave under unilateral interface are still not sufficiently investigated. It is the purpose ofthis paper to present a review on the current situations,problems and prospects in this research sphere.
