得到了多个正交相干玻色子粒子构成的相干态之间的m体算符矩阵元的一般表达式。这使得相干态形式主义被应用到拥有任意大数量的内在激发量子的状态。为了说明，该方法被应用于二维振子模型（U（3）模型），以计算在大N极限下所有激发态的能量。
A general expression is obtained for the matrix element of an m-body operator between coherent states constructed from multiple orthogonal coherent boson species. This allows the coherent state formalism to be applied to states possessing an arbitrarily large number of intrinsic excitation quanta. For illustration, the formalism is applied to the two-dimensional vibron model (U(3) model), to calculate the energies of all excited states in the large-N limit.
