摘　　要：通过对结构位移计算公式中弯矩进行幂级数展开,得出计算结果是“系数×端点弯矩值×端点弯矩值×构件长度”的形式,发现了计算结果的系数与幂指数之间的关系,提出了系数法全新的计算方法,并对各种基本情况和组合情况进行了计算,给出了计算图表,随后举一个算例进行说明解题过程并指出该方法的优点。Through opening out the bending moments formula of displacement calculation, the result is the format of “eoeiticient × values of endpoints of rod on bending moment graph × values of endpoints of rod on bending moment graph x the length of component”, and the relationship between the coefficient of the result and the index was discovered. A new coefficient method is put forward. The displacement calculation has been done in the elementary eases and combined eases, and the calculation diagram has been given. An example has been given in order to show the process of solving problems and its advantages.
