Abstract:The dual relationshp between current-mode circuits and voltage-modecircuits is discussed,according to the node voltage KCL equations and the eloop currentKVL equations Dual transformation method is presented to derive current-mode cir-cuit. Examples are g

Abstract:Considering the n-th order mixed neutral equations,we establish several comparison theorems which show that ,under appropriate hypotheses ,the oscillation problems of the neutral equations are determined by the oscillation problems of the associated nonn

Abstract:We study a class of scalar reaction-diffusion equations with two time lagsdefind on the unit circle. By using the results obtained in[9] and employing the Birkhoffmormal form due to Chossat,Golubitsky and Keyfitz[2],the existence of a 2-dimensional invari

Abstract:We obtain the estimattion of time lagging bound for uniform stability and uniform asymptotic stability of linear time lagging systems of liigher dimension by using V(x) function with a step by step proof by contradiction.

Abstract:对格上的Ｃ－拓扑，Ｎ－拓扑，Ｌ－拓扑，Ｏ－拓扑以及Ｉ－拓扑的精细进行了比较，得到了一些新结果。

Abstract:First an inequalityof high-dimensional dihedral angle cosine square sumis givern with the smallest lower bound.Then an inequality of the central line length ofn-dimensional simplex is discussed.In the end , the author has shown some useful re-sults.

Abstract:A method for shape estimation of piles by using of measured responsedata of a pile head is proposed in this paper. This method can be used to determine thesize , type and location of a defect in a pile, Practical examples have shown that thismethod is acc

Abstract:Much interference always existing in industry control systems has beensummarized and some simple anti-interference methods proved to be effective in practicehave been intrduced at the same time.

Abstract:When the grinding-balls are casted in the high-grade chromite ,he production cost is high, the casting craft is complicated,the demands on control parametersare very strict, the rate of production is lower,and so on,These make its further appliation and d

Abstract:The research processes of YRBM which takes Machining,Steel slab,Rivet, Stamp and Welding as one according to the aim of practising GT-CAPP in enter-prises(trades)are discussed. At the same time, the effects on Process Planning Decisionof CAPP ard discusse

Abstract:Tall Building Structure with large open space at ground floor level is divided into frame substructure and shear wall substructure by cutting the connectingbeams. The vibration equation for shear wall substructure is set up according to Timo-shenko cantil

Abstract:Plane stress finite element method is used for the nonlinear analysis ofearthquake response of RC shear wall structure, a more realistic assessment of struc-tural behavior is obtained thn using the commonly used storey model and bar system model. Non-comp

Abstract:The plane integration expression method is a new practical technique for astructure designer to draw the working drowings of reinforced concrete structure. The essence of the method is that many complicated structural members , such as multispan and multi

Abstract:The ventilation of railway runnel is affected by factors as the runningmode of trains,natural wind, piston wind caused by train running, mechanical ventilation method, ete. There is no systematical study about the ventilation of two-way rail-way tunnel ti

Abstract:假设计算区域的上空面和二侧面为自由边界，地面和建筑物的各面为壁函数的边界，计算网格为３６×３０×２７，构造１０ｍ×１０ｍ×１０ｍ建筑数值风洞，采用ｋ－ε湍流模型，对该数值风洞进行了风绕流数值计算。得到了建筑表面压力分布及建筑周围速度矢量图，与实验结果比较表明，该数值风洞是可行的。

Abstract:In the laboratory, we regenerated the waste water glass sand mixtureusing flue gas, recovered the waste sand successfally and desulpharized flue gas at thesame time. The result of experiment showed that recovered waste sand is up to the castsand standard.

Abstract:The factor and mechanism of crack of carbon grophilic products duringbaking have been discussed.The measurement and method far preventing crack duringbaking have been put forward.
