The soil organic and clay influence remarkably the soil aggregate "original stability" and "collapse velocity", they are the mostly intrinsic factor to soil aggregate erosion.
The intrinsic frequency of P-wave increases because of existence of apparatus and its amplitude has been influenced by velocity ratio of P-wave vs S-wave.
纵波的固有频率因仪器的存在而增大,纵波幅度还受地层的纵、横波速度比的影响。
