| 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含集中量的杆件弯曲时的平衡微分方程的应用，从而推广了材料力学中杆件弯曲时的平衡微分方程。该方程更全面更精确地反映了杆件弯曲这一物理现象。作者把它称为梁弯曲时的广义平衡微分方程。

| Abstract: | A general method for handling the concentrated/distributed variables is introduced,and the application of the differential equations of equilibrium during building the method for solving problem of bending a lever (pole part) having some concentrated variables invalued is discussed emphasizedly,and therefore , the area of application of those differential equations has been enlarged, the equation has shown itself more completely and precisely reflect the physical phanomena of the lever-bending so that it is refered to as generalized equilibium differential equation for beam bending. |
