Abstract:In this paper, based on variational principle and bilinear coordinate transformation, a spline Kantorovich method using cubic B-spline function is presented to obtain an approximate solution for the free vibration problem of arbitrary quadrilateral plates

Abstract:In this paper, the boundness, Holder continuity and W~(2,s)-regularity of a nonlinear elliptic variational inequality with superlinearly increasing term are obtained under some assumptions, via De Giorgi's and Ladyzenskaya's methods which were used to dea

Abstract:In this paper, we discuss the elliptic elements in four dimensional sense-preserving Mobius transformations, and obtain two elementary properties of them. Based on these properties, we prove the maximum property of three kinds of elliptic subgroups in E(R

Abstract:The formulas of the total potential energy of arbitrary thin- walled open cross section member counting in the geometric non-linear factors is deduced. The deductions are based on the most general finite deformation theory and the two assumptions that"the

Abstract:In this paper, concept of boundary geometrical imperfection during postbuckling process for shallow spherical shell is first presented. The effects of the declination of the rectangular boundary on postbuckling process are also studied by integrated metho

Abstract:This paper expounded the interrelation and regularity between graphical methods(such as vanishing point method, measuring point method, etc.) and matrix transformation method for drawing two-point perspective drawings. Based on on-the-spot and elaborate o

Abstract:In this paper, the aerodynamic model and the mathematical model of the bus body are set up. The correctness of the models is verified by using computer simulation for pressure distribution and comparison between experimental results and computational valu

Abstract:In this paper, a Comprehensive evalution index for the dynamic characteristic and the economy of automobile is proposed. According to the automobile kinematical features determined by the acceleration process in continuous gearshifting and the"six operati

Abstract:In this paper, the condition of service and employ request of rubbing piece formed by tank catepillar pin and tank caterpillar plank, the coordination of tank caterpillar pin strength, tenacity and capacity against rubbing away, the materials used in the

Abstract:According to the data of model experiment and theory analysis, this paper put forward the principle and the condition of power obtainable of modulation, and discuss the reason for that one can't obtain the power at the presentation of resonance. The resul

Abstract:In this paper, we introduce the conditions and the rules for anaerobic polymerization on some kinds of(meth) acrylate, obtained by a series of optimization experiments. The comprehensive performance of anaerobic abhesives made according to these condition

Abstract:Electrode selectivities toward quaternary ammoniums are controlled by the ability of the cation to be extracted into the membrane phase. We has proved in this paper theoretically that logK_(ij) can be expressed as function of alkyl chain length of quatern

Abstract:This paper studies the application of a feedstuff extracted from the waste residue liquid of amylum industry to raise chickensproteinaceous chicken meal. Under the condition of balancing daily grain feed, the feed stuff is used in the expriment to take pl

Abstract:Based on the measuring of the floating substances and COD of the dusty water of an Electric Power Plant, considering the effect of the floating substances on COD, and through the experiment of the filtering, cleansing and mixing of the dusty water as well

Abstract:In this paper, we study the oscillation of solutions of neutral delay differential equations. Our results extend and improve some theorems in papers[1,3,10]. We also obtain sufficient conditions for Eq.(1) to have a nonoscillatory solution.
