中文摘要：
将传统落球法测定液体粘滞系数改为升球法进行试验,很好地控制小球上升匀速段,提高精度;同时配以激光光电计时器计时,使测量结果更加精准.另外,本套装置中配设水循环系统,室温和变温下的液体粘滞系数均可测量.
英文摘要：
We had been used rising-ball method instead of the traditional falling-ball method, which can control the ball rising at a constant speed to increase the measuring accuracy.Moreover,Laser photoelectric tim-er was used to record time to make the measurement more accurate.In addition,this device had water circula-tion system,which can be used to measure liquid viscosity coefficient at room temperature and variable temper-ature.
