In the experiment of liquid viscosity measured by rotary column method, the uniform drop time and distance are calculated theoretically.
通过理论计算得到了“转柱法测液体粘度”实验中砝码下落达到匀速所需要的时间和运动距离。
2
The surviving distance of the cryogenic liquid column is defined.
定义了低温液柱的生存距离。
3
Base on the analysis of the usual measure column gear teeth distance error, we rebuilt the usual measure way, and design a king of auto measure way for column gear teeth distance error.
