• 中文摘要： 層狀介質對平面波之反應函數在地震記錄解釋上很重要。本文由波線理論推導層狀介質對在地表以下任一位置之震源之SH反應函數。此反應函數為一容易計算的有限多項式之簡單函數，而此多項式之每一項對應於介質中兩個介面間多重反射波之和。因此，此介質反應函數不僅有很明顯的物理解釋，便利於未來顯性逆推方法之推導，而且可用以很有效地合成地震記錄。 本文將所推導的層狀介質反應函數與 Kennett 和 Kerry [16]結果之展開式逐項對比，因此提供了一個探討SH波在層狀介質中之波線－波動雙重性之基礎。
• 英文摘要： The model response function for a plane wave plays a major role in interpreting seismograms. In thispaper, an explicit complete SH model response function having a physical interpretation has been derivedby ray theory for a horizontally-layered medium with a buried source. This function is related explicitlyto the ray reflections between interfaces in a simple compact form; it is not only useful for the develop-ment of an explicit inversion method, but also provides a suitable mathematical form for the efficientstable computation of synthetic seismograms. The derived response function has been compared withKennett and Kerry's [16] result term by term, and thus has provided a basis for a ray-wave duality for SHwaves in the layered medium.
