The crosscorrelation technology was used to measure solid velocity.
采用互相关技术测量固体的流速。
Amplitude degressions with distance of single event waveform and crosscorrelation functions are much similar.
互相关函数的最大幅度与事件波形的振幅随距离具有相同的衰减规律。
The signals we get at the top of the drill string and at the surface are continuous, so only after crosscorrelation can the useful information be available.
