摘要
用类量子力学的观点和方法，计及行星和太阳的二体效应，进一步探讨了太阳系角动量分布的规律性。所得各种理论结果均与天文观测值相符合。特别是对天文学中著名的疑难问题：质量超过太阳系总质量９９．８％的太阳的角动量竟不到太阳系总角动量的０．６％，在某种程度上做出了定量的说明。就理论的自洽性而言，本文有二点改进：一是在类Ｐｌａｎｃｋ常数η中包含的常数λ已可统一地取值；二是在一定的主量子数ｎ下，总角量子数ｊ的取值已找到了一定的物理依据。
Following the viewpoint and the method of quasi-quantum mechanics, this paper deals with the two-body effect and makes a further investigation on the regularity of the angular momentum distribution of the solar system. All the theoretical data obtained are well consistent with astronomical observations. in particular, a quantitative interpretation is given to the well-known knotty problem, i. e. 'the angular momentum of the sun whose mass exceeds the total mass of the solar system by 99.8% is no more than 0.6% of the total angular momentum of the solar system'. As far as the self-consistency of the theory is concerned, this article has made two improvements: a Planck's-constant-like η contains a constant λ which can take on regular numerical values, and at a certain principal quantum number n, the quantum number j of the total angular momentum is found to be based on a particular physical rule.
