• 关于波函数的疑惑--------------------------------有这句话“在某个时刻在空间某点找到粒子的机率与波函数的平方成正比” 我感到困惑的是这句话有矛盾,因为说机率应该不能限制在某个时刻吧,比如说抛一枚硬币,只能说“抛一次硬币,出现正面向上的概率为二分之一”而不能说“在某个时刻抛一次硬币,出现正面向上的概率为二分之一”吧我的意思就是说在说某个事件的概率时不能限制在某个时刻吧,因为限制在某个时刻后,一但过了这个时刻后就不能回到这个时刻了嘛.所以我觉得上面的话应该改成“在空间某点找到粒子的机率与波函数的平方成正比”,不限制在某个时刻,否则就没有意义了.呵呵,希望大家能帮下忙啊,最近学量子力学学得脑袋都瘫痪了.
