摘要
根据量子统计中相空间的理论知识,采用两种不同的方法给出了热真空态的Husimi分布函数,并给出了热真空态的Wehrl墒。最后与相应混合态的Husimi分布函数进行比较,得出来热真空态的Husimi分布函数与混合态的Husimi分布函数是相一致的结论。
Based on quantum phase space of quantum vacuum state is obtained by two methods. And then the Compared to the Husimi distribution function of the co distribution function of the thermal vacuum state agrees statistics, the Husimi distribution function of thermal entropy of the thermal vacuum state rresponding mixed state, it is found with that of the corresponding mixed can be obtained that the Husimi state.
