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.

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。

Elastic wave theory based on homogeneous and continuous medium model may lead to incorrect explanation of seismic response to geological structure and may even lead to erroneous explanation.

基于均匀的、连续介质模型建立的弹性波动理论可能导致对地球结构地震响应的不当解释，有时可能是错误解释。
