非十進制數
英文
non decimal numeral-
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。A symbol that represents one of the nonnegative integers smaller than the radix. in decimal notation, one of the characters from0to9
表示比數基小的非負整數的符號。在十進制記數法中，每位數是0到9的一個數字。Nonparametric model is widely used in the practical problems, the reason is that the form of the regression function in the nonparametric model is free, and the limits to the random variate ( x, y ) are fewer. in the past several decades, this model is studied carefully by the researchers of statistics, and many achievements are arrived in both theorial fields and in applicational fields
非參數回歸模型，由於其回歸函數的形式可以任意，而且對隨機變量（ x ， y ）的分佈限制較少，因而在實際中有著廣泛的應用背景。幾十年來，統計工作者對這一模型進行了深入細致的研究。無論在理論上還是應用上，都取得了許多優秀成果。Storing information in molecules of dna could allow for an information density of approximately 1 bit per cubic nanometer. the energy consumed by dna molecular biology computing is billionth of that consumed by one conventional computer. the characteristics of dna molecular biology computing mentioned above which are high parallelism, huge capability and low consumption are incomparable and irreplaceable to the existing computers and parallel ones
Dna分子生物演算法具有高度的并行性，運算速度快； dna作為信息的載體其貯存的容量非常之大， 1立方米的dna溶液可存儲1萬億億的二進制數據； dna分子生物計算所消耗的能量只有一臺電子計算機完成同樣計算所消耗的能量的十億分之一； dan計算的上述特性，即運算的高度并行性、大容量、低消耗是目前計算機和并行計算機所無法比擬和替代的。Except for research on the unsteady flow at lower lock approach in siyang, jiangsu province by physical model, a two - dimensional numerical model is developed to explore the alternate research method in this paper. through studying the project using physical model and numerical model simultaneously, the governing equations, numerical algorithm and the computation accuracy of the numerical model are analyzed. comparison between computed results and experimental data gives that computed results is well agree with measured data under several water level cases, which indicates that the numerical model is valid and reliable
通過數學模型和物理模型的同步研究，對數學模型的控制方程、數值計算方法以及數值模擬的精度與物理模型試驗進行了比較分析，同實測資料驗證的結果表明：該數學模型與物理模型一樣在不同的水位組合，不同的運行工況條件下都能正確地模擬下游引航道非恆定流的實際水力情況，模型計算結果與實測資料十分吻合，說明建立的數學模型是合理的，結果是可靠的，可以利用該數學模型進行船閘下游引航道非恆定流特性的研究。分享友人
