  1. Although uml activity diagram is magnitude component in uml, which agrees with modeling system dynamic process and describing workflow, it is immature in itself with the characteristic of non - oriented - object and essentially different from other uml diagram, and need to be ameliorated especially when applicated in workflow, own to the following limitation : firstly, activity diagram describes the behaviors of object class that response the inner action, so uml activity diagram is generally on the assumption of that there is no interruption caused by outer events during the process and no time defer, which limits the ability of uml activity diagram discribing complicated process ; secondly, user cannot obtain enough information of object data, and cannot make sure the character of mutual objects because of actually complicated object and relatively simple object expression in uml activity diagram ; lastly, owe to lacking rigorous mathematical basis and strict, effective methods of validation and analysis, uml activity diagram cannot support the simulation and optimization of workflow, let alone optimizating the model based on the result

    Uml活動圖是uml的重要組成部分，適用於系統動態行為建模和描述工作流，與uml的其他圖形工具不同，它本質上是非面向對象的，而且其本身並不成熟，仍在改進之中，特別是在工作流應用方面。首先， uml活動圖描述的是響應內部處理的對象類的行為， uml活動圖通常假定在整個計算處理的過程中沒有外部事件引起的中斷，也沒有時間的延遲，這就限制了uml活動圖對一些復雜過程描述能力。第二，現實世界業務過程涉及的對象數據十分復雜，但是uml活動圖的對象語義卻非常簡略，用戶基本上無法從uml活動圖中獲取關于對象數據的信息，也不能確定參與交互的對象的特徵。
  2.

  4. Abstract : the generalized shrunken prediction of finite population is introduced, using generalized shrunken least squares estimator of linear regression models. with respect to prediction mean squared error, a necessary and sufficient condition for superiority of a generalized shrunken prediction over the best linear unbiased prediction is obtained. in the case of linear combination of every unit index, a linear restricting prediction is introduced and then a necessary and sufficient condition for superiority of linear restricting prediction over the best linear unbiased prediction is devived

  5. 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。
