Prestack migration of common shot records is very sensitive to the velocityinput, and demands a kind of continuation formula which can adapt to both vertical and lateral velocity variations.
共炮记录叠前偏移对输入的速度非常敏感，要求偏移中所使用的延拓公式能较为精确地适应速度的纵横向变化。

It shows that the signal will become bad with the increase of transmission velocity and distance by comparing the wave figure and eye diagram of input and output pulse.
通过比较输入与输出信号脉冲波形和眼图发现，随着传输速率和传输距离的增加输出信号劣化。

In hydraulic synchronizing lifting technology for oversize structure, computer output PWM signal as the input current of proportional valve is used to control the velocity of hydraulic cylinder.
