| 摘 要： | 介绍了利用δ函数统一处理集中量与分布量的一般方法。着重讨论了这种方法在建立合集中量的杆件扭转时的平衡微分方程的应用。从而推广了材料力学中扭转变形时的平衡微分方程。该方程更全面更精确地反映了杆件扭转这一物理现象。作者把其称为轴扭转时的广义平衡微分方程。

| Abstract: | presents a general method for the unified treatment of concentrated and distributed variables by using δ-function. The application of the method to obtaining the equilibrium differential equations for a twisted shaft which includes concentrated variables are emphasised. Then, the equilibrium differential equations for the twist deformation topic in the mechaniCS of material are extended. The equations represent the phySical meaning of a lever twist more comprehensiely and pricisely.Authers call this method as generalized equilibriUm differential equations of shaft twisting. |
