摘　　要：研究了量子力学中不同力学量可同时具有确定值的问题 .结果表明 ,此问题取决于量子体系的状态 ,而与力学量算符可否对易问题有联系 ,但不构成因果关系 .The question that different mechanical quantities of quantum mechanics have definition values simultaneously is studied. As a result, the question depends on the states of quantum system. The question relates whether the operator of mechanical quantity can commute,but they don't form the causal relation.

关 键 词：对易 本征态 确定值 量子力学 力学量 量子体系 力学量算符
