摘　　要：本文利用3个D函数的积分规则讨论了2个、3个和4个角动量从非耦合表象到耦合表象的变换,并讨论了它们与角动量投影方法的一致性,一方面可作为量子力学教学内容的扩展,另一方面也为量子体系中常用的角动量投影方法提供了一种检验其正确性的桥梁。By using the integral rule of three D functions, this paper discusses the change of two, three and four angle momentum from non-coupling presentation to coupling presentation. It also discusses their consistency with the projection method of angle momentum. On one hand, it can be taken as the extension of the teaching content of quantum mechanics; on the other hand, it provides the projection method of angle momentum often used in quantum system with a bridge to test its correctness.
