The nonlinear magneto - elastic basic equations of thin current - carrying strip - plate are built, based on the kinetic equations, the geometric equations, the physical equations and the electrodynamics equations of thin current - carrying plate, the normal cauchy form nonlinear differential equations, which includes ten basic unknown functions in all, are obtained by means of variable replacement method
摘要在所建立的載流條形薄板的非線性磁彈性基本方程運動方程、幾何方程、物理方程和電動力學方程的基礎上，通過變量代換，整理成含有10個基本未知函數的標準柯西型方程。 -
( 3 ) optimization design principle of long - short - pile composite foundation is put forward, base on which replacement ratio and pile length is taken as design variable, bearing capacity, settlement, stratum strength and other demands acted as constraint function, pile cost taken as objective function, so the optimization design model of long - short - pile composite foundation is built
（ 3 ）提出了長短樁復合地基優化設計原理，在此基礎上將置換率和樁長作為設計變量，承載力、沉降、下臥層強度等要求作為約束函數，總制樁費用作為目標函數，建立出長短樁復合地基優化設計數學模型。 -
In this paper, based on the method of variable replacement, real parameters di > 0 ( i = 1, 2, . ., n ) which can be adjusted, are introduced ingeniously. we establish some new sufficient conditions for the existence, uniqueness and global exponential stability of the equilibrium, periodic solution and almost periodic solution of neural networks with time - varying delays by means of the method of variation of parameters, fixed point theorem and some analysis techniques
本文巧妙地引入可調實參數d _ i 0 （ i = 1 ， 2 ， … ， n ） ，藉助常數變易法、變量替換、不動點定理和一些分析技巧，對具可變時滯的神經網路的平衡點、周期解、概周期解的存在性和全局指數穩定性建立了一些新的充分條件。 -
