摘　　要：在宏观条件下总结出来熵增原理可否推广到宇观系统？１９９４年以来一系列工作集中在形成恒星的孤立气体团以及背景辐射两个方面．集中介绍这些工作．主要结果是，对于尺度大于１０光年左右的宇观系统，熵增原理不再适用；随着我们宇宙的膨胀。Can be generalized the principle of entropy increase, w hich summed for many maroscopic system on the surface of the earth,to a cosmosco pic system?Since 1994,my works are about the entropy of a isolated gas group,whi ch is forming a star,and the background radiation.The main results are that the principle of entropy increase is no longer valid for some cosmoscopic systems of a scale bigger than 10 light years;and the total entropy of our cosmos is decrea sing with its expanding.
