In the stability design of the bottom slab of stilling basin or water cushion pool for a long time past, a little attention was paid to the pulseload on the slab.
以往在消力池或水垫塘底板的稳定性设计中，很少注意板块上脉动荷载的作用。

This modification caused a heavy "pulse" of load on the server, which made it easier to measure the time it took for resultant replications.
修改之后会给服务器带来较大的“负载冲击”，这有利于测量完成最终复制所需的时间。

But the step motor efficiency is low, the ability is not big, load drag pulse equivalent cannot too big, speed range is not big.
