摘要
对落球法测量液体黏度实验进行改进,充分利用物理天平称量精度较高的特性,采用称量及求比值的方法求出小球在液体中受力的大小.该方法避免了一些计算误差和测量误差,可提高测量精度.
The experiment of measuring liquid viscosity with falling-ball method was improved by making use of high precision balance to measure the force on the small ball in liquid.The new method could avoid some computing errors and measurement errors and improve the accuracy.
