The usual Enskog-Chapman method of solution of the Boltzmann equation is inadequate in the Knudsen layer, a region adjacent to the solid wall with the thick of a few mean free paths of the gas molecules. In recent years the BGK model method has been widely used. This method is adequate in the Knudsen layer. The author suggests another model equation of the Boltzmann equation. Perhaps this model equation somewhat improves the degree of approximation. In this article, the model is applied to the plane Couette's...

The usual Enskog-Chapman method of solution of the Boltzmann equation is inadequate in the Knudsen layer, a region adjacent to the solid wall with the thick of a few mean free paths of the gas molecules. In recent years the BGK model method has been widely used. This method is adequate in the Knudsen layer. The author suggests another model equation of the Boltzmann equation. Perhaps this model equation somewhat improves the degree of approximation. In this article, the model is applied to the plane Couette's flow problem, the formal solution has been obtained and the first approximate solution by the method of iteration has been given. This solution gives correct results in both molecular flow and viscous flow limits.

在靠近固体壁几个气体分子自由程的区域(克鲁曾Knudsen层)内,通常解玻耳兹曼方程式所 用的恩一查(Enskog-Chapman)方法已不适用。近年来使用较多的BGK模型方法,可以在 Knudsen层内应用。本文中提出玻氏方程式的另一种模型方程式。这种模型方程式可能在近似程 度上有些改进。文中应用这种模型于平面Couette流问题,求出其形式解,并用迭代方法求出一 次近似解。这个解在分子流和粘性流两个极限情况下都给出正确的结果。

The problem of solving the Dirac equation in a Kerr space-time has long been unresolved. In 1976, S. Chandrasekhar solved the decoupling problem of the Dirac equation with non-zero rest mass in a Kerr background, thus provided the possibility of attacking the problem of the Hawking evaporation of Dirac particles. In this paper, starting from Chandrasekhar's results, we find the solution of the Dirac equation with non-zero rest mass just out side the event horizon of a nearly extreme Kerr black hole and sucessfully...

The problem of solving the Dirac equation in a Kerr space-time has long been unresolved. In 1976, S. Chandrasekhar solved the decoupling problem of the Dirac equation with non-zero rest mass in a Kerr background, thus provided the possibility of attacking the problem of the Hawking evaporation of Dirac particles. In this paper, starting from Chandrasekhar's results, we find the solution of the Dirac equation with non-zero rest mass just out side the event horizon of a nearly extreme Kerr black hole and sucessfully derived the Hawking thermal formula.

Under the conditions similar to industrial ammonia synthesis, the intrinsic kinetics of Series "A" Catalysts (A110, A106) made in China for ammonia synthesis has been investigated.

在近似工业合成氨的实际条件下,研究了我国研制的A系工业催化剂表面上的本征动力学。在用简单的方程的修正表达式对实验数据作电算处理之后,证明了A系催化剂表面的氨合成动力学用方程来描述是基本适用的、有效的。经过电子计算机的优化计算,认为动力学参数a值取0.5较好。所求得的表观活化能与许多学者的研究结果相近。因此,本报告为A系催化剂的工程应用计算,推荐了一个适用的动力学模型以及相应的动力学参数。 通过动力学数据的比较,证实了A110催化剂比A106及国外同类型产品催化剂具有更高的催化活性及较低的活性温区。
