摘要
给出了动能矩阵为对角矩阵,在A=aE和A≠aE(E为单位矩阵)两种情况下同时对角化势能矩阵求简正坐标的一般方法,并提出了先改变坐标标度,后对角化新势能矩阵或用频率特征矩阵的伴随矩阵的任一列求简正坐标的另两种方法.
When the kinetic energy matrix have been diagonalzed, under the condition A=aE or A≠aE,the common method of finding normal coordinate is given.Besides,other two methods of finding normal coordinate are given,one method is by changing the coordinate scales and diagonaling the new kinetic energy matrix, the other method is by changing the coordinate scales and using arbitrary row of adjoint matrix of the frequency eigen matrix.
