摘要
在直梁上的载荷集度中引入奇异函数，表示集中力、集中力偶的作用，建立载荷剪力弯矩之间的微分关系，具有普遍意义。
Odd function is introduced in loaded distribution of straight beam.With the odd function,we can express the effect of concentrical force and couple and set up the differential relations of shear and wind couple,so it is of universal significance.
