所以作者主要是应用一维弹性波理论及板壳振动理论对局部噪声屏蔽进行理论研究，并用试验来验证理论分析的可靠性。

So one-dimensional elastic wave and plate vibration response theory are mainly applied to study the structure and experiments are made to verify the validity of the theory.

提出了采用P波广角反射和P波高速层内局部转换广角反射波消除火成岩高速层对地震波的屏蔽作用。

This paper proposed to overcome the shielding effects by using wide-angle P-wave reflections and localized converted waves (PSPPSP).
