Abstract:现行设计规范对梁柱在不等端弯矩作用下等效弯矩系数β的取值因采用了近似表达式的形式，故与实际情况有较大误差。同时，由于现行设计方法不能提供二阶最大弯矩的准确位置，也给设计带来了不便。本文运用弯矩分布函数，建议对β的取值可以采用图表的方法，使β值的求解更精确、更实用。同时，在此基础上，还提出了等效跨长的概念。

Abstract:The optimization of tube settling process should be confined within the optimization of whole water treatment plant design under the conditions of higher criteria on potable water.Tube settling process has a better suitability for the challenge of new regulation of drinking water quality. When optimizing tube settling process,the effects on which filtration and flocculation processes have been exerted should be considered.The design surface load of tube settling should be lower than that in existing design codes.The configuration of tube module can be selected as two-or multi-layer module to make full use of the separation capacity of tube module.The suitable cross-section type of tube is also needed to be selected carefully,adopting an excellent one which is knoumas square cross-section type of tube.The layout of tube settler,the arrangement of tube module,the connection between tube settler and flocculator,and the construction and operation management of tube settling process are also factors for the optimization of tube settling process.

Abstract:The Mond_Weir duality for generalized vector optimization is dealt with in this paper.This paper proves the theorems on weak duality between primary problem and dual problem,direct duality and inverse duality.

Abstract:This paper introduces the method of how to improve superfine sand grading and fineness modulus by the use of crushed_run stone which contains 20 percent of stone chippings smaller than 5 mm,and the technical means of how to formulate superfine_sand high_strength concrete(HSC) by blending fly_ash and admixture.In addition,based on the analysis of the results obtained from numerous comparative experiments on factors influencing concrete strength,the parameters of mix proportion for C50 and C60 superfine_sand HSC are determined.

Abstract:应用画法几何探讨空间四杆各杆件的定位问题。空间几何问题需要用“形”和“数”来确定，经过图示图解后建立起数学模型，然后通过计算获得结果，较之单纯的数学分析法使解题简单明了、形象直观、易于掌握。

Abstract:This paper discusses programming method used for displaying and amplifying chinese words on screen.It also describes the problems about music program. The package programmes consist of moving graphic program, music program amplification program and os on. For example about package program, there are three programmes with C Language.

Abstract:Based on the fractal principle, this paper suggests a calculating expression of the relative luminance distribution in cloudy sky which belongs to the category of intermediate sky, it was proved to be suitable.

Abstract:Principally, Direct-heat-exchange is the main way of water- heating .But it should not exclude the existence and development of the way of Indirect-heat-exchange. Indirect-heat-exchange is based on the theory of the turbulent flow-heating.According to the theory, a series of new heating equipments were made. Two of them are discussed in this thesis. Also it introduces two kinds of heater which have found wide application recently:hemi-fast open water heater and the semi-volume heater.

Abstract:On the basis of stability factors of crack extension,the stability of compact tension Specimens is analyzed, especially the effect of the size of concrete specimens on the stability.

Abstract:This paper expounds the important meaning to guarantee and raise the reliability taking precautions against fire calamities for the system of city lifeline engineering.It quotes a large number of fire and fail cases to explain that it is a complex system engineering to evaluate the abiity of the fire systems in the city lifeline cngineering.It epresents some methods to evaluate the reliability of complex systems, these methods are being used in the different trades at the present. After comparing these evaluation methods, this paper presents the advantages and defects of analy tical method of the fail tree.It also shows clearly that this method can completely be competent at the job to analyze the reliability taking precautions against fire calamities for the city lifeline engi neering.

Abstract:This paper studies the duality of the Multiobjective optimization problem involving generalized F-invex functions in Banach space. The constraint qualification and lemma 1 are introduced. The Wolfe type of duality and Mond-Weir type of duality are obtained. Strong and weak duaity theorems and other results are given under weaker F- invexity assumptions.

Abstract:According to the two kinds of expressions of the quadratic functions and the power functoin for describing the non_linear seepage flow,this paper advances that the two kinds of expressions should have identity,that is to say they can transform each other.And by means of least square method,the relational expression for the two kinds of functions to transform each other is derived.From the verification of the two kinds of particular seepage flow(laminal flow and adequate turbulent flow)and the hypothetic data,it has been shown that the relational expression can express the identity between them adequately,it can afford the references to the further research on the non_linear seepage flow.

Abstract:In the structural geology,we have long continued to use the method of C.M.Nevin to determine the stratigraphic duplicate and incompletement caused by the strike fault,the method is complicated and trivial.So using the following law could make it simpler than before:if the stratum of the upthrown side raises up on the strike fault,the surface stratum is incomplete,on the contrary,if the stratum of the upthrown side slopes down,then the surface stratum is duplicated.

Abstract:The improvement of Data Communication has made the design of line driver,line receiver and other interface circuits complicated.In accordance with some communication protocols,this paper recommends several IC interface chips and their application in overcoming the influence of noise.

Abstract:Following the rapid development of the revolutions in housing system,reconstruction of old buildings is rising.In order to make the reconstruction proceed smoothly,in this paper the author studies the secondary parts,reinforcing foundation,dismantlement of some parts of an old building,linkage of new and old frames,solutions for the four relationships,and others.
