半逆法 meaning in English

semi inverse method

While in traditional elasticity mechanics , we make our best to eliminate the unknown variables and can get the simplest equation in a brief form . at the same time , the rank of equation is increased , so we cannot solve the equation by direct method and have to resort to semi - converse method
而传统的弹性力学，其求解方法是尽量消元以使未知量减少，方程形式简单，宁可让方程阶次提高，故数学物理方法中最基本的分离变量法就难以实施，只能采用半逆法。
