| 摘 要： | 从量子绝热过程中粒子在各个能级上分布的概率不变这一特点出发，通过对比分析大量粒子经历量子绝热过程后在宏观上的表现及宏观系统在可逆绝热过程中其微观表现特点，证明了对近独立粒子系统，微观粒子经历量子绝热过程时宏观上表现为可逆绝热过程，而宏观可逆绝热过程在微观上表现为每个粒子经历量子绝热过程．

| Abstract: | Starting from the trait of the quantum adiabatic process in which the distribution of a particle＇s probability among different energy levels doesn＇t change, we analyses the characteristics of quantum adiabatic processes and macroscopic reversible adiabatic process. It is shown that for ideal gas a quantum adiabatic process is equal to a macroscopic reversible adiabatic process. |
