A family of new trigonometric means

The object of the present paper is to introduce a new family of trigonometric means which are regular. Many interesting inclusion relations with well-known nontrigonometric means and lastly a Tauberian theorem have been established.     

非线性干涉滤光片N形反射光双稳器件的研究

对Ｎ形反射光双稳器件的结构进行了理论设计和实验研究，对光双稳的重要参数δＩ０、δＩｒ与初始失调量δ之间的关系进行了描绘，并通过引入ＺｎＳｅ薄膜的色散关系，使这一理论方法具有自洽性。最后，文章给出了通过这一方法设计的非线性干涉滤光片Ｎ形反射光双稳器件的实验结果。     

Dispersion of electromagnetic waves in the presence of magnetic monopoles of electron mass in a uniform magnetic field

The dispersion relation of electromagnetic waves in the presence of magnetic monopoles of electron mass in a uniform magnetic field is obtained. The waves of the frequencyω in the range ω_ϱi<Ω_i<ω<Ω _e <ω_ϱa are analysed. It is shown that the monopole charges lead to observable effects. Finally, the results are applied to a typical pulsar.     

Dispersion theory relations and charmed baryon couplings

Dispersion theory sum rules proposed by Atkinson have been obtained for the invariant amplitudes of the elastic pion-charmed baryon scattering process. Saturating the sum rules with the known intermediate states, we obtain the pion-charmed baryon coupling constants.     

矩阵乘幂的一种显式公式

本文给出用线性Ｄｉｏｐｈａｎｔｕｓ方程的解计算矩阵乘幂的显式公式，并给出常系数联立线性递推关系组的解的显式表达式。     

一般代数对象的挠理论

1993年Puczylowski在用公理系统构造的其中元素称为代数的对象类中建立了根与半单类的一般理论。本文的目的是在这种最具广泛性的代数系统中讨论挠理论，用格论方法给出它的一些特征刻划。     

渐变折射率介质中标准矢量波函数的构成

研究了在渐变折射率介质中构成标准矢量波函数的必要条件。研究结果表明在渐变折射率介质中构成标准矢量波函数除了仍需遵循Morse-Feshbach判据外，领示矢量仅能选取与折射率变化方向一致的那根坐标轴的单位矢量。     

心血管内流场的高质量模拟实验研究（Ⅰ）──动态流体双折射测试原理与分析方法

本文系统地讨论了以动态流体双折射方法实现心血管内流场的高质量模拟测试的基本理论和实用分析方法。首先，分析了稳态流动和振荡剪切流中光──力学关系的差异，提出脉动流中简化的光──力学关系假设，然后给出其适用于低频脉动流动的实验验证。为使医学和生物力学研究人员易于掌握，又提出一种简单新颖的局域分析法。     

Traces of fuzzy binary relations

In this paper the right and left trace of a fuzzy binary relation is defined and investigated. Basic properties of a fuzzy relation (such as reflexivity, different kinds of transitivity, linearity, etc.) are characterized by means of its traces.     

蕴涵格的滤子及同余关系

在蕴涵格中引和了蕴涵滤子的概念，讨论了蕴涵滤子的一些基本性质，并由此建立了由素蕴涵滤子决定的同余关系及其商蕴涵格，以便为Fuzz推理建立了严格的逻辑基础作些必要的准备。
