给出了一个描写多极形变系统集体运动的普遍公式 ,在那里 ,动能被拆分成三部分 :体坐标框架下的振动 ,体坐标系围绕实验室系的转动以及振动与转动的耦合 .定义了 18种不同的八极形变内禀系 ,按其度规矩阵的行列式分为 9个不同的类 .其中以参数a30 ,a31,a32 ,b31和a30 ,a31,b31,b32 定义的八极形变内禀系 ,度规矩阵的行列式 (分别为 9a232 和 9b23 2 )是最简单的 A general formula describing the collective motion of a multipole system is presented, where the kinetic energy is split into three parts: the vibration in the frame of the body coordinate, the rotation of the body coordinate system around the laboratory, and the coupling of vibration and rotation. 18 different types of octagonal deformation of the intrinsic system, according to its metric matrix determinant is divided into nine different categories. Which parameters a30, a31, a32, b31 and a30, a31, b31, b32 defined eight Deformation of the intrinsic system, metric matrix determinants (respectively 9a232 and 9b23 2) is the most simple
