引力塌缩系统的熵变

引力塌缩系统的熵变 ENTROPY CHARGE OF GRAVITATIONAL COLLAPE SYSTEMS 张祖全 Zhang Zuquan 1 first-author 江汉大学应用物理学系 江汉大学应用物理学系 Department of Applied Physics,Jianghan University Department of Applied Physics,Jianghan University 在共动坐标系下，对引力塌缩系统的熵变进行了研究，证明了理想流体系统的塌缩是等熵过程，有辐射热流的开放系统的塌缩是减熵过程．对非理想流体系统推出了熵变的一般公式，并应用到有辐射中微子的塌缩过程，其总熵是减少的． Entropy charge of gravitational collape systems have been studed in cop moveing coordinate systems.It have been geven that collape process is equal entropy in perfect fluid systems and collape process is reduction entropy in thermal radiation ope systems.The generality formula of entropy charge have been geven in non perfect fluid systems.The total entropy reduced in neutrinos radiation systems. 塌缩 熵 黑洞 理想流体 collape entropy black hole perfect fluid P142.6 湖北省教委科研基金 1998-03-01 2021-04-01 3
