Abstract:Second order elliptic variational inequalities were considered , and a kind of nonoverlapping domain decomposition method with two subdomains was proposed . Conver- gence and convergent rate of the method were obtained .

Abstract:The pmperties such as connection , separation etc in a de moorage quotient al- gebra of topology are investigated and a sufficient and necessary condition for de morgan quo- tient algebra of topology to be T1 is established .

Abstract:The Souslin sets are the sets more widely than Borel sets. We investigate the density regularity properties of Souslin sets for Hausdorff S -dimensional measure , and give some sufficient conditions for the regularity properties of Souslin sets .

Abstract:Using the model of classical molecular interaction,we have investigated theformation of XC60 with a rare atom X added inside or outside the C60 cage.The equilibriumposition of X in CC60 and the stability have been discussed.It is shown that the equilibri

Abstract:The principle and result of measuring effective density of gap states in amor- phous silicon with type of ZC36 micmgalvanometer which is cheap equipment made in P R China are first reported in this paper. The result is in agreement with one measured with

Abstract:The nonlinear dynamic and static response are anaiyzed for urthotropic truncated conical shells under uniform distributed loading , The governing equations of the system are founded . The approximate solutions of the dynamic and static response and the dy

Abstract:Dynamical behavior of the thin elastic plates in noninertia system is plentiful . The paper firstly analyses the equilibrium points and obtains the parametric equations of ho- moclinic and periodic orbits of such system . Furtheninore , we investigate the

Abstract:Thin organic polydiethylamines films with properties of good chemical stabil- ity and good adhesion to glass and other substrates were first successfully prepared by plasma polymerization with diethylamine as a monomer . The affection of processing condit

Abstract:Bismuth and zinc salts of 0,0-dialkyl dithiophosphoric acid are synthesized. With the aid of a solution-supporting additive , the are used in high water base fluid . By fric- tion tnd weat test on four-ball machine and practical grinding test , their lubr

Abstract:A method for updating the dynamic finite element model of a elastic linkage using measured eigenfrequencies is proposed. The proposed updating technique directly modi- fies the selected local physical parameters of the initial finite element model . The m

Abstract:In an auto-controlled plug conveying system, the pressure drop was found to be dependent on plug velocity and plug length and to vary linearly , regionally and periodically with plug Length when plug velocity changed. This relationship was first expounde

Abstract:This paper presents a way of the design and implementation of a MELSEC- NOVELL gateway based on analyzing NOVELL NET and MELSECNET NET . lt. gives a king of way to solve the problem of the interconnection of heterogeneous nets.

Abstract:By introducing vertex rigid rotation as DOF , two plane sector elements are presented. Numerical results demonstrate that very good accuracy is achieved and they are the practical elements to analyze the structures with circular bnundary .

Abstract:Thicknesses of typical pavement structures determined by design specification fro cement concrete Pavement on gighway are used for eiliability analysis.Results show that the values of the factors reflectin reliability of strutufe in the specificaytion are

Abstract:根据灰色系统理论及预测控制理论，结合斜拉桥的施工特点，提出了一个较大为实秀的斜拉桥施工控制系统－灰色预测控制系统，详细介绍了了这种系统的基本思路，技术路线，实施步骤以及实际应用情形，采用该系统可以对斜拉桥的线形和索力实施较为有效的双控。

Abstract:Dyeing inteninediate dinitrotchlorobenzene is toxic for microorganism and is one of the most difficulty-treated watewater. A pretreatment method for improving the bio- logical treatability and removing the (30D and colorization using combined iron scrap-c

Abstract:By means of the Object Oriented Programming (oop), the identically Dy- namic I-D Graph (IDIDG) is successfully displayed and applied under WINDOWS circum- stances. lt can completely replace the traditional operating methodology of I-D Graph (lDG) and will

Abstract:This article introduces structure design in high buildings automatic fire con- trol and alarm system. Functions, hardware, structure and control procedure of the system are described in the paper. The key circuit details are formulated, main program flows

Abstract:Based on the continuous-values logic for building a mathematically slrn.et- rical model of color vision, algebraic solutions of the boundaries of the li.lean f.ttcti.s ..re obtained . Some sarmples of solving the boundaries of solid Boolean functions A -

Abstract:This paper evaluated and analysed the most important three financial opti-mization models (mortgage settlement model,structuring collateralized mortgage obligationsmodel,and glogal return shaping model),which are used in financial engineering.
