In fact, the deep overlapping of the wavepacket of particles implies new interactions which are technically called nonlinear ( in the sense of depending on powers of the wavefunctions bigger than one ), nonlocal ( in the sense that they are extended over the volume of wave - overlappings which cannot be evidently reduced to finite number of isolated points ), as well as nonpotential ( in the sense of being of contact / zero { range type for which the notion of action - at - a - distance potential has no mathematical or physical meaning of any type }
事實上，粒子相互之間深深重疊的波包意味著新型的相互作用，技術上它可稱之為非線性意義為它們取決于波函數大於1次的幕而定，為非局部意義為它們的延伸超越了波重疊的體積，使其顯然無法再縮小到有限數孤立點，以及為非潛能意義為相互接觸零距離，在這種情況下一定距離下作用的潛勢不再有任何數學上或物理上的意義。 -

一方面，從商品供求關系模型、宏觀動態供需模型、具體的報價驅動供需分析，再到信息不對稱情況下和零和博弈情況下的供需分析，提出對于股票這樣的虛擬資本形式，價格形成機制仍主要體現在信息、參與者和量價關系等多個方面。 -
So in normal atoms with electrons in stationary states, the probability of the electron being within the nucleus ( or somewhere else in atom within similarly small volume ) is nearly zero according to the uncertainty principle ( it is nearly zero as the nucleus has a volume and is not a point )
因此在正常具有電子的原子里處于穩定狀態，電子在核內的概率（或者處于原子里的某處類似小體積）是幾乎為零按照測不準原理（它幾乎為零如同核子具有體積而不是零那樣） 。 -
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
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。
