    Binary relation analysis is aprimary means of things mechanism analysis in pansystems methodology. According to the practical background on which people's preferences to bundles of commodities in economic activities may not be transitive, we propose a kind of special pansystems binary relation called quasi-transitive relation. Under the condition of quasitransitive preferences, we discuss the central issue of general equilibrium in mathematical economics, From the point of view of pansystems methodology, we analyse in detail the binary relations between prices and demand quantities of goods, between prices and supply quantities of glut goods and, between goods and the minimum prices. Then we prove the existence of equilibrium in model of pure exchange economy under quasi-transitive preferences.

    In this paper, we discuss some mathematical physics problems and stabilized algorithm principle on the continuation of electromagnetic fields in non-homogeneous medium with vertical smoothing variance. At first, a partial differential equation of the second order satisfying the vertical component of the magnetic field under the vertical non-homogeneous medium is derived, starting off with fundamental equation of electromagnetic fields, and the continuation problem of the field is reduced to solving the Cauchy problem for the corresponding elliptic equation of the second order, according to practical background. Then the formal expression for the field continuation is obtained by the method of the Fourier transform, and the precise analytic formulas for the field continuation under a number of special non-homogeneous medium are given. Finally, using the regularization method, the stabilizated formula for the field continuation is established, the discretization form of resulting formula is given, and the selected principles of the corresponding regularization parameter are shown.

    本文讨论具垂向光滑变化的非均匀介质中电磁场延拓的数学物理问题及稳定化的算法原理。首先从电磁场的基本方程出发,导出了垂向非均匀介质下磁场的垂直分量所满足的二阶偏微分方程,并且依照实际背景将场的延拓问题化归为解相应二阶椭圆型方程的Cauchy问题。接着利用Fourier变换方法得到了场延拓的形式表达式,然后给出了几种特殊垂向非均匀介质下场延拓的精确解析公式。最后,应用正则化方法建立了场延拓的稳定化的公式,给出了所得公式的离散化形式,同时指出了相应正则化参数的选择原则。
