白矮星是负熵系统

摘要

应用正、负能谱热力学理论(PNES热力学理论), 通过白矮星熵的演化对白矮星的初期演化阶段作了仔细分析, 得出了白矮星在其初期收缩过程中是一个负熵系统, 白矮星的演化由其正熵(电子子系的熵)Se和负熵(氦离子子系的熵)He之间的竞争决定, 当He比Se增长得快时, 则系统的总熵将更负, 它必将更趋于有序态; 反之, 当He比Se增长得慢时, 系统的负熵将减少, 于是系统的有序程度将减少.%By using the positive and negative energy spectrum thermodynamical theory (PNES thermodynamical theory), through the evolution of entropy of white dwarf star, the evolution of white dwarf star at the early stage has been analysed carefuly. We draw a conclusion that the white dwarf star is a negative entropy system at the early constriction process. The course of evolution of white dwarf star will be decided by the competition between the pasitive entropy (electron entropy) Se and negative entropy (heliumion entropy) He. If the He increases speedly than Se the negative entropy of system must be even more negative, and then the system will be tended to more order. Otherwise, while the He increases slowly than Se, the negative entropy of system must be decreased and then the level of ording of system will be decreased.
