摘要
叙述了打靶法的基本原理．打靶法是解微分方程的数值方法，其基本思想是将微分方程的边值问题转化为初值问题来求解，其特点是精度高，程序简单，实用性强．本文将打靶法与力法相结合用于解超静定梁，并给出了求解等截面、变截面超静定梁弯矩。
The shooting,method is a numerical method to solve differential equations,its fundamental thought is that the problems of boundary value of differential equation is transfered to problemes of initial value to solve.Its features are that the accuracy is high,the program is simple and the applied character is good.The fundamental of the shooting method and has been told,and being combined with the forcing method has been used to solve the statically indederminate beams.The paper has given the calculated examples in bending moments,deflections and rotating angles of the uniform beam and un-uniform beam as well as their diagrams.
