摘要： 首先从非对易相空间中重新确定微观状态个数和配分函数来讨论在非对易相空间中单原分子理想气体的热力学性质.结果显示非对易效应不能在理想气体系统的内能、物态方程、热容量等宏观热力学性质中测量出.然而发现系统的配分函数和熵发生变化,表示在非对易效应作用下系统的能量简并度和系统的无序度发生变化.
关键词: 非对易相空间, 热力学性质, 理想气体
Abstract: The effect of noncommutativity of phase space on thermodynamical properties of single atom ideal gas system is discussed by redefining the number of microstates and partition function. The result shows that the non- commutativity effect can not be measured in the macro state functions such as the internal energy, equation of state and heat capacity. Moreover, our result also show that the number of microstates and partition function changed due to the changes in the degeneracy of energy levels and the disorder levels of the system.
Key words: noncommutative phase space, thermodynamical properties, ideal gas
