A general expression of the transformation between master and slave degree of freedoms was derived from the power series expansion of the matrix. The general expression was also expressed as a power series of the unknown eigenvalues.

• 在用动力缩聚法求单个特征值的过程中,本文利用矩阵的幂级数展开,把主、辅坐标之间的变换矩阵表示为未知特征值的幂级数形式,并在此基础上分析出了可以用该方法计算的特征值的范围以及求出这些特征值的收敛速度。
