| Abstract: | The coupling of angular momentums is an important content in quantum mechanics. Angular momentum projection is also an important content in the academic journals for related research realm. They have close relationship between each other. We study the couplings for two, three and four angular momentums, the total angular momentum projections of them and the coincidence between them by using the formulas of two D functions coupling and the integration formula of three D functions. The research, provides an easier method for checking the correctness of both numerical calculations with each other. |

| Keywords: | coupling of angular momentums angular momentum projection coincidence CG coefficient |
