等导重根特征对的泰勒展开

Taylor Expansion of the Eigenpairs with a Repeated Latent Root Having Equal Derivatives

讨论多参数非亏损特征对的可微性，推导了具有等同一阶偏导数的重根特征对的计算公式，进而得到了它们的泰勒展开式．

The differentiability of the eigenpairs with a nondefective latent root is investigated, where vibratory systems are described by general multi-parameter models. Computational formulae of the eigenpairs with a repeated root which have equal first partial derivatives are derived, and their Taylor expansions are accomplished further.
