Based on statistics, a new equation shown below was derived to represent the physical adsorption on solid surfaces after modifying the assumptions used by Langmuir for deriving the equation of monomolecular adsorption:

本文扩展了Langmuir单层吸附模型中的单分子作用与吸附能分布假定,提出了一个新的物理吸附模型.Langmuir公式,Freundlich公式,Temkin’公式均为其中的特殊情况.当假定吸附能呈均匀密度分布时,得到吸附等温式:n=kln[1+(b_0P)~(1/m)],1/M为一个吸附中心平均吸附的吸附质分子的个数.随M与对比压力P/P_0的函数关系不同,可用以统一并定量地描述各种类型的物理吸附等温线.

质量充分大的星体,在演化晚期会因引力作用而引起坍缩。在相对论天体物理学中,在球对称的情况下,这个坍缩过程已为不少学者研究过,但这些工作大多局限于最简单的状态方程(p=0)。本文对均匀密度理想气体星球的引力坍缩作了一些探讨。

In this paper,we have obtained some interior solutions of the Ein- stein's field equations for ideal gas sphere.These solutions satisfy physical conditions inside the sphere.

R.C.Tolman 给出了 Einstein 场方程的球对称非静态解,此解纯属度规间关系,并未真正求出度规来。本文采用理想气体星球模型,对均匀密度星求解场方程,得到类 Tol-man 解,利用能量动量守恒定律,得出了与时间反演下的 Lemaitre 度规类似的非 Tolman型解,最后讨论ω′=0时场方程的解。
