说明：  PMSM起动仿真模型，双闭环控制，仅供参考。能够无位置传感器起动(PMSM Start Simulation Model)

This function calculates displacement response at interfaces of an elastic multilayered medium to a vertically propagating unitary SV or SH elastic wave. The function can be used to calculate the displacement response in a layered soil profile. Transfer functions between interfaces can be easily calculated by division of the total (=upward+downward) displacement response on the corresponding interfaces.
