2 .對(duì)于尺寸、應(yīng)力和位移約束的問題，將應(yīng)力約束化為動(dòng)態(tài)下限，用單位虛荷載方法將位移約束近似顯式化，構(gòu)造優(yōu)化問題的數(shù)學(xué)規(guī)劃模型，將其對(duì)偶規(guī)劃處理為二次規(guī)劃問題，采用lemke算法進(jìn)行求解，得到滿足尺寸、應(yīng)力和位移約束條件的截面最優(yōu)解。
This feature reflects the physical phenomenon of breaking of waves and development of shock waves . in the fields of fulid dynamics , ( 0 . 2 . 1 ) is an approximation of small visvosity phenomenon . if viscosity ( or the diffusion term , two derivatives ) are added to ( 0 . 2 . 1 ) , it can be researched in the classical way which say that the solutions become very smooth immediately even for coarse inital data because of the diffusion of viscosity . a natural idea ( method of regularity ) is obtained as follows : solutions of the viscous convection - diffusion pr oblem approachs to the solutions of ( 0 . 2 . 1 ) when the viscosity goes to zeros . another method is numerical method such as difference methods , finite element method , spectrum method or finite volume method etc . numerical solutions which is constructed from the numerical scheme approximate to the solutions of the hyperbolic con - ervation laws ( 0 . 2 . 1 ) as the discretation parameter goes to zero . the aim of these two methods is to construct approximate solutions and then to conside the stability of approximate so - lutions ( i , e . the upper bound of approximate solutions in the suitable norms , especally for that independent of the approximate parameters ) . using the compactness framework ( such as bv compactness , l1 compactness and compensated compactness etc ) and the fact that the truncation is small , the approximate function consquence approch to a function which is exactly the solutions of ( 0 . 2 . 1 ) in some sense of definiton
