摘要
根据最小作用量原理,另辟蹊径,系统推导了广义相对论的广义守恒定理、能量守恒定理与角动量守恒定理,特别是简明扼要和较完整地推出带有自旋角动量守恒的角动量守恒定理这一新的表述结果,在广义相对论理论中还是第一次.
A general conservation law and the energy-momentum and angular momentum conservation law in general relativity are derived systematically and successfully based on a least-action principle. Thus by far, it is also the first time that the angular conservation law with spin angular momentum conservation in general relativity has formulated so succinctly and practicably.
