摘要: 从公式推导、 不同模型数值试验和实际资料处理等3个方面, 系统研究了P波速度vPP对接收函数H(地壳厚度)-k(波速比)叠加搜索结果的影响. 结果表明, vPP的变化与H正相关, 与k负相关; 且地壳模型越复杂, vPP对H的影响越大.Abstract: This paper systematically investigates the effect of P wave velocity on the H-k stacking results of receiver functions by three aspects of theoretical analyses, numerical tests and observed data processing. The results show that the P wave velocity is positively correlated with crustal depth H, and negatively correlated with wave velocity ratio k. Moreover, the more complex the crust model is, the larger effect P wave velocity has on H.
