| 摘 要： | 在梁的荷载、剪力图与弯矩图相互间微分关系的基础上 ,推导出相邻 2截面内力的积分关系式 ,避免了直接用截面法求解控制截面内力的麻烦 ,淡化了力学概念 ,使内力问题转化为数学上的面积问题 ,提高了作图效率

| Abstract: | Based on the differential relations of the loading,shearing force and moment, the intergral relations on any two neighboring sections in a beam are derived, therefore,the trouble of solving the inner forces of section controlled is avoided,the mechanics idea is weakened.and the inner forces changes into the area problem,solving the chart making becomes more effective. |
