摘　　要：讨论绕水平定轴转动的圆盘和跨过圆盘的细绳组成的力学系统,在考虑二者的质量及之间的摩擦的情况下,导出了细绳张力的计算式.A string system is discussed, in which the circular plate goes through the circular plate. The formula of calculating the tension in of both objects and the friction between them being factored in. rotates around a fixed axis and the string the string is given in the case of the mass
