快速多极边界元法解的存在唯一性

本对求解3维弹性摩擦接触问题的快速多极边界元法(FM—BEM)在数学理论上作了深入探讨．首先，利用向量和子空间理论找出快速优化广义极小残余算法(GMRES(m))求解边界元方程组所满足的代数条件．使对工程用FM—BEM解的研究转化为对代数问题的讨论，然后．分三步证明了FM-BEM解的存在唯一性，为FM-BEM求解弹性摩擦接触工程问题提供强有力的数学支撑．

Fuzzy Entropy： Axiomatic Definition and Neural Networks Model

The measure of uncertainty is adopted as a measure of information. The measures of fuzziness are known as fuzzy information measures. The measure of a quantity of fuzzy information gained from a fuzzy set or fuzzy system is known as fuzzy entropy. Fuzzy entropy has been focused and studied by many researchers in various fields. In this paper, firstly, the axiomatic definition of fuzzy entropy is discussed. Then, neural networks model of fuzzy entropy is proposed, based on the computing capability of neural networks. In the end, two examples are discussed to show the efficiency of the model.

Effect of Nuclear Binding Energy to K Factor

We modify the square of virtual photon four-momentum by using nuclear binding energy formula, and calculate the effect of nuclear binding energy to K factor and Compton subprocess and annihilate subprocess in A-A collision Drell-Yan process. The outcome indicates that the effect of nuclear binding energy to K factor is obvious in little x region and it would disappear gradually as x increases.
