摘要
从几种不同途径初步探索了减少大型结构特征向量导数计算的时间以及对计算机内存空间的依赖，从而发现了各个不同途径中存在的问题，并指出了解决这些问题的方向。
Several ways that are hsed to reduce the inner store space and time of computer required in the calculation of large dimensional eigenvector derivatives are explored in this paper. The existing prob-lems in different ways were found. The directions solving these problems are pointed out. Those men-tioned-above are useful to further investigation of the subject of this paper.
