| 摘 要： | 在Torres-Vega和Frederick所提出来的量子相空间理论(简作TF量子相空间理论)的框架下,研究了量子相空间表象下的微扰理论,得出了量子相空间理论框架下的非简并微扰理论(perturbation theory),得到了体系存在微扰情况下的能量和波函数,并且以一维电解质在外加电场中的极化率为例,在量子相空间表象下,对量子体系的状态进行了分析.以期探索出将量子相空间理论和各种近似方法结合起来处理真实体系的问题. |

| Abstract: | The perturbation quantum system was discussed within the framework of quantum phase space representation formulated by Torres-Vega and Frederick(TF) and studied the nondegenerate perturbation theory.The energy and the wave functions of the system in quantum phase space representation has been obtained;the one dimensional anharmonic oscillator system was used for an example to analyses the behaviour of quantum system in quantum phase space representation.The actual physical system in quantum phase space representation by using the approximate methods has been discussed. |
| Keywords: | TF quantum phase space perturbation theory the approximate methods |
