摘　　要：针对三个系数矩阵都对称,质量矩阵非奇异和测量数据部分测得的二次模型修正问题,主要研究了它的可解性。首先,给出了该问题的研究背景和文献综述并提出一种特殊部分测量数据的二次有限元模型修正问题,给出两个重要引理,最后,采用矩阵分块法求得问题的可解条件。Based on quadratic model updating problem of partially measurement data with three symmetric coefficient matrix and mass matrix nonsingular,the solvability of it is mainly studied. Firstly,the problems of the background,literature review and quadratic finite element model updating problems with a special partially measurement data are presented; then two important lemmas are given; finally,matrix partition method is used to obtain solvability conditions of the problem.
