當考慮粘性后,即在數學上反映為( 0 . 1 . 1 )中多了擴散項(二階導數項) ,即使很粗糙的初始數據,解在瞬間內變的很光滑,這由於流體的粘性擴散引起,這種對流-擴散問題可用古典的微分方程來研究。自然的想法就是當粘性趨于零時,帶粘性的對流-擴散問題的解在某意義下趨于無粘性問題( 0 . 1 . 1 )的解,這就是正則化方法。另一辦法從離散(數值)角度上研究僅有對流項的守恆律( 0 . 1 . 1 ) ,如構造它的差分格式,甚至更一般的有限體積格式,有限元及譜方法等,從這些格式構造近似解(常表現為分片多項式)來逼近原守恆律的解。It is difficult to analytically solve the inequality constrained nlps in the dual space, due to the linear lagrangian. a perturbed ( regularized ) lagrangjan approach is proposed, which provides an analytic solution of the dual variables in terms of primal variables
