摘　　要：论文给出了宇宙真空的定义,建立了宇宙真空特性理论。分析了前人理论不能解释宇宙真空特性的原因,比较了理论和观测数据的符合性。推导出了表征大气特性方程,指出前人理论仅适用于行星表面附近,而该新理论适合全宇宙空间。用这一理论计算了太阳系行星大气总质量及行星际大气密度分布,对人类探测宇宙实践有指导意义。The theory of cosmic vacuum characteristics is established in this paper,the definition of cosmic vacuum is given.The reason why the previous theory can not explain the universe vacuum properties is analyzed.The compliance of the theory and observation data is checked.Characteristic equation of atmosphere is derived.It is pointed out that the theory is valid not only near the surface of the planet but also for the whole space.Total atmospheric mass of a planet in solar system is calculated with the planetary atmospheric number density distribution given by this theory.The divergence problem of the total atmospheric molecular number is solved,therefore the obstacles for discussion on the cosmic vacuum characteristics is removed.It is helpful to human space exploration.
