摘要
本文指出用概率方法与用泛函方法定义量子力学中“可观察量在态中的平均值”是有区别的,而唯一正确的方法应为采用概率的方法从而澄清了绝大多数量子力学文献中对于“平均值”
It is pointed out in this article the mean value of an observable A in the state φ defined by probabilistic method is different from one did by functional analysis method in quantum mechanics.It is further prover that the unique correct definition is the probobilistic one,thus helping to clarify some of the misconceptions on the mean value in guantum mechanics.
