矩阵法拟定化学反应机理软件

本软件是根据Happel和Sellers提出的矩阵法编制的。用户只需输入基元反应方程式及其系数矩阵,即可得出全部动力学上有意义的反应路线。本软件不但可用于单一总反应的物系,也可用于多个总反应的物系,既适于均相反应,也适于非均相反应。它是拟定化学反应机理的有力工具。本软件用BASIC语言编写,由DOS3.3以上版本支持,可在APPLE-Ⅱ及其兼容机上运行,使用十分方便。     

左消半群M与幂单半群B的Schǔzenberger积

本文讨论了每个元都有幂等元作为右单位元的左消半群与幂单半群N的Schuzenberger积M◇N的ρ类，证明了这种半群M与N的Schuzenberger积M◇N的ρ类是右E一半适合半群和弱E-headged半群．     

The Isoelectric Point and the Points of Zero Charge of Fe-Al-Mg Hydrotalcite-like Compounds

The relation of the isoelectric point (IEP) and the point of zero net charge (PZNC) of the hydrotalcite-like compounds was discussed. It was found that the IEP does not equal to the PZNC and the IEP is higher than the PZNC. The structural positive charges existing in the HTlc,which cause the difference between the IEP and the PZNC. The effects of the structural positive charges of the HTlc on its IEP and PZNC are the same as the specific adsorption of metal cations.     

Geometric Characterizations for Subgroups of PU（1, n; C）

In this paper, we discuss non-elementary subgroups and discontinuous subgroups of PU(1,n; C), and give their geometric characterizations.     

超幂等环的交换性

证明了下面的命题:若对环R中任意元x都存在整数k(x)>1使x~(k(?))=x,则R为交换环。这是Jacobson的一个著名结果的较大的改进。还得到了更普遍的结果。     

Covariant Perturbation Theory of Non—Abelian Kinetic Theory

A “double perturbation” theory is presented in the framework of the kinetic theory of quark-gluon plasma.A solvable set of equations from the double perturbation are derived and proven to be gauge invariant.The Landau damping rate for the plasmon at zero momentum is shown to be a convergent series in correlators.     

Bound States of the S-Wave Equation with Equal Scalar and Vector Standard Eckart Potential

A supersymmetric technique for the bound-state solutions of the s-wave Klein-Gordon equation with equal scalar and vector standard Eckart-type potential is proposed. Its exact solutions are obtained. Possible generalization of our approach is outlined.
