| 摘 要： | 研究了行星及行星际大气环境特性。为了克服用玻耳兹曼公式（BF）计算行星大气总分子数时出现的发散困难，在玻耳兹曼公式中引入新的归一化函数g（r），得到了新的行星大气分布律公式（RBF），探讨了归一化函数的物理意义。和Jeans的理论进行了比较。用RBF计算了太阳系中木星、土星、天王星、海王星和土卫六的大气密度随高度的分布。这些结果对于开展行星探测工作有一定的指导意义。

| Abstract: | The environment characters of atmosphere of planetary and interplanetary space are studied.A revised Boltzmann formula(RBF) by introducing a normalization factor in Boltzmann formula(BF) in order to overcome the divergence problem of total molecular number of atmosphere is proposed,and compared with Jeans theory.The physical meaning of the normalization factor is also examined.The atmospheric number density distributions of Jupiter,Saturn,Uranus,Neptune and Titan upon height are evaluated in this paper.These results might be helpful to the detecting planetary and interplanetary space.. |
