OPTIMALLY ACCURATE PETROV-GALERKIN METHOD OF FINITE ELEMENTS

We perform analysis for a finite elements method applied to the singular self-adjoint problem.This method uses continuous piecewise polynomial spaces for the trial and the test spaces.We fit the trial polynomial space by piecewise exponentials and we apply so exponentially fitted Galerkin method to singular self-adjomt problem by approximating driving terms by Lagrange piecewise polynomials,linear,quadratic and cubic.Wt measure the erroe in max norm.We show that method is optimal of the first order in the error estimate,We also give numerical results for the Galerkin approximation.

NEWTON-LIK E METNODS IN PARTIALLY ORDERED BANACH SPACES

We provide convergence results and error estimates for Newton-like methods in generalized Banachspaces.The idea of a generalized norm is used whichis defined to be a map from a linear space into a partiallyordered Banach space.Convergence results and error estimates are improved compared with the real normtheory.     

SPECTRAL TECHNIQUES FOR OFF-LINE TESTING AND DIAGNOSIS OF COMPUTER SYSTEMS

In this paper we present some of our recent results on applications of spec-tral techniques over finite fields to the problems of testing and diagnosis ofcomputer systems.     

On the behaviour of artificial head transfer system applied to acoustic evaluation researches for halls

The author has made tests for an artificial head transfer system whichis modelled on a Chinese male on its main physical behaviour such as frequencyresponses,frequency response differences between the front and the rear inci-dences,as will as on its important hearing behaviour such as localization,theperception of distance and room dimensions.The results verify that this kind ofartificial head transfer system can be used as one of effective tools of acousticevaluation researches for halls.     

CO和H_2在沉淀铁催化剂上的化学吸附和程序升温脱附

铁催化剂是一种重要的F-T 合成催化剂。本文的目的是通过CO 和H_2在浆态相F-T合成采用的无载体沉淀铁催化剂上的化学吸附和程序升温脱附(TPD)的实验结果,考察钾的加入对催化剂性能的影响。实验采用共沉淀法制备的Fe-Cu(Fe65w%;Cu 0.6w%,其余为平衡氧)和Fe-Cu-K(Fe,Cu 含量同上,K0.1w%,其余为平衡氧)两种催化剂。程序升温脱附实验在装有四极质谱仪的吸附-解吸系统内进行。化学吸附用Chemisorb 2800装置测

离子对内电子转移型染料阴离子-翁盐阳离子光敏体系中的溶剂效应和结构效应

本文研究了溶剂效应和结构效应对染料碘翁盐光物理, 光化学性质的影响。观察到在溶剂中离子对可以各种形式存在, 如紧密离子对、溶剂分隔离子对或溶剂化的自由离子, 溶剂的极性不仅影响各种存在形式的光谱性质, 而且影响它们之间的平衡关系, 进而影响离子对体系的物理化学性质。染料母核和碘翁阳离子的结构均对离子对体系的性质有影响。光诱导电子转移反应的热力学驱动力越大, 反应速度越快。用分子模拟技术(Molecular Modeling)对离子对体系的立体结构进行了研究, 为理解离子对体系的各种物理化学行为提供了重要的参考。
