摘　　要：对多管落球法测液体粘度进行了理论分析与实验研究 ,在满足斯托克斯公式要求的在横向与纵向均为无限宽广的液体条件下 ,得到了理想的测量结果 .By theoretical analysis and experimental research for measurement of viscosity of liquid using falling balls with many pipes, it is found that the condition of liquid unlimited broad in horizontal and vertical requested by Stokes formula is satisfied. Therefore, the idealized result is obtained.
