| 摘 要： | 数值试验结果指出,用接收函数反演地壳速度结构时,在正演和反演过程中使用不匹配的地壳模型参数化方式,将对结果产生不良影响;同时发现,在处理实际资料时将接收函数归一化,可能会丢弃介质信息.在此基础上,改进了接收函数和近邻算法反演地壳速度结构的程序,并用来反演了海拉尔台下的地壳速度结构.

| Abstract: | The numerical test shows that the ill effect will be brought in the inversion result of velocity structure with receiver functions when the parameterized models in the forwarding and inversing procedures are not matched. Some information will be lost in the real data processing when the observed and synthetic receiver functions are normalized respectively.Accordingly, the inversion program of Neighborhood Algorithm with receiver functions is improved and then the crust velocity structure under station HLR is obtained in this paper. |
