摘要
当一连续谱量子体系具有某一确定能量时,通常的量子力学用单个连续定态来描写它的性质,所得到的任何力学量的期待值都将为零或无穷大。本文以数学定理的形式指出该体系具有一类新的决定论的、物理内容明显的结果。经典力学结果是这些结果的经典极限,通常的量子力学期待值作为一种统计结果而包含在本文结果之内。
When a quantum system with continuous spectrum has a definite anergy, ordinary quantum mechanics uses a single continuous stationary state to describe its properties, the expectation values for arbitrary physical quantities are therefore either infinity or zero. In this paper we point out in the form of mathematical theorem that the system possesses new and deterministic results with evident physical meanings. Classical results for the system are the classical limit cases of these results, and the ordinarv expectation values are the statistical cases of our results.
