摘要 研究了在一定的简化模式下,孤立系趋近平衡的过程中量子态和量子态组分布熵随时间变化的预测规律.揭示用有限次大量重复性模拟实验所得的量子态组分布熵有多大的实验偏差,并将原文献中只限于对系统的几十个量子态组分布熵的研究扩大到对系统中数以万计的量子态的分布熵的研究.按重复实验法和本文提出的预测法同时设计两套熵增原理的计算机模拟程序,验证表明,预测规律具有高度的准确性. Time-dependent predictions of distribution entropy in quantum state/quantum state grouPSwere conducted under conditions of a certain simplified model for an isolated system approaching to equilibrium,with test deviations revealed in a limited number of simulations done relatedly quite a lot in previousworks. Increasing the number of investigations on quantum-state entropy distribution from several dozens ofgroup-distribution entropy of quantum states for the system in the reference books to dozens of thousands ofdistribution entropy of quantum states,the author programmed two different softwares for computer simulation of the principle of entropy increasement in accordance with the repetition method as above and the prediction method proPOSed. Comparing and checking their results,the latter was proved of high accuracy.
