Based on the basic principle of reflection and transmission in the process of the propagation of logitudinal wave, this paper recounts a new theory and method for the application of pile body completeness inspection data with reflection wave method to the quantitative determination of apparent reflection coefficients and the round travelling time of reflection wave.
从纵波传播过程的反射和透射的基本原理出发，介绍了反射波法桩身完整性检测数据在频率域中定量确定视反射系数和反射波往返时间的一种新的理论和方法。
3) fast steering mirror
快速反射镜
1.
A precise tracking system mainly composed of a fast steering mirror and position sensitive detector is established.

5) strong reflection spot
强反射点
1.
In the structure oil and gas accumulated, seismic datas as reflection coefficient, velocity and frequency would change, the "strong reflection spot" or "weak reflection spot" is formed above the oil and gas layer and the unusualness of the low frequency and low-velocity appears.
