测量液体粘滞系数实验是大学物理的一个经典实验,常用的方法有落球法、毛细管法、落针法、转筒法等。比较以上几种实验方法,毛细管法、落针法、转筒法等几种方法要想提高测量结果的精度,惟有从改善仪器的工艺制作水平上下工夫,且效果难以保证。反观落球法,其所需仪器简单(只需量筒和小球),成品钢球一致性非常好,只要对测量的方法进行适当 Measurement of liquid viscosity coefficient experiment is a classic experiment in university physics, commonly used methods are falling ball method, capillary method, needle drop method, drum method and so on. Comparison of the above several experimental methods, capillary method, needle drop method, rotary method and other methods to improve the accuracy of the measurement results, only from improving the level of equipment manufacturing process, and the effect is difficult to guarantee. The other hand, the ball method, the required equipment is simple (only cylinder and ball), finished steel consistency is very good, as long as the measurement method is appropriate
