According to the working principle of thermo - electrode, we demonstrate the structure of enlarged reflection area and the structure of step broaden waveguide to improve the switch ' s performance and bring down the driving power. according to the fabricating condition of our lab, we proposed simple wet - etching method to fabricate the oversized waveguides and peeling - off method to fabricate the electrode
針對全內反射和熱電極的作用特點，在全內反射型熱光開關的設計中提出了擴大反射區結構和漸變展寬結構，理論模擬和實驗結果表明該方法能有效地提高了開關性能，降低了驅動功率。 -
In order to input chinese character naturally from keyboard, our next step is presenting a new input method named " stroke simulation ". the main idea of the method is inputting the feature points of a stroke, such as up - point, twist - point and down - point, instead of inputting a stroke directly from keyboard. the trail of the feature points we extracted from a stroke shoud be able to shape the stroke. the most attractive point of this method is that it allows users input strokes continually without an extra key to separate two continuous strokes
為了在鍵盤上實現漢字的自然輸入，論文提出一種「模擬筆劃」的漢字輸入新方法，這種方法特別適用在目前信息產品上廣泛使用的數字小鍵盤上，它不直接在鍵盤上輸入漢字筆劃，而是根據筆劃的形狀特徵和運筆方向輸入漢字筆劃的起點、折點和落點等筆劃特徵點。 -
Aim at ubiquitous parallel multi - reservoir structure in our country ' s basin, the universal objective function including coefficient bi embodying a spatial significance difference at different flood control points and variable ai denoting a selection of scheduling mode is established, which provide a valid intervenor interface for flood control consultation decision. according to the real - time requirement, a model of reservoir storage allocation is proposed, which embody basic idea of phasic compensation. passing the dynamic correction to cut down the disadvantageous influence that indetermination result in on the certain degree, joining together the step alternation solving method, this model can maximally consider bias of decision makers, ensure the rationality and practicability of the solutions
針對我國流域中普遍存在的並聯庫群結構，論文提出包含不同防洪點重要性的系數_ i和選擇調度模式的變量_ i的通用目標函數，為防洪會商決策，提供了有效的人工干預介面，根據實時性要求提出動態分配防洪庫容的庫容分配方法，體現了相機補償的基本思想，通過動態修正在一定程度上可以削減不確定性造成的不利影響，結合分步迭代求解技術，能最大限度體現決策者的偏好，保障解的合理性和可操作性。 -
Impedance - matching balanced traction transformers ( balanced transformers in this paper for short ) are step - down transformers, they transfer symmetrical three phase voltage in primary side to perpendicular two phase voltage in secondary side. they are different from any other transformers, so their short - circuit current analysis and short - circuit test method must be taken into special account
阻抗匹配平衡牽引變壓器（本文中簡稱平衡變壓器）是一種將一次側三相對稱電壓變換為二次側二相垂直電壓的降壓變壓器，它不同於已有的任何一種變壓器，短路電流的分析計算和短路試驗必須予以重新研究。 -
Different parts in the same seamless system perform different tasks, and the use of oo method becomes the key point in the system integration of netfeaf. by making full use of some strategies like " from top to down ", " divide and conquer " and " step by step ", with the help of oo method, netfeaf creates a new method to build the whole integrated system : using one class hierarchy map to fully stand for the structure of netfeaf, and different parts in netfeaf like cluster class library, fea class library, web fea class library and gravity wharf cad class library can also be further explained by their sub class hierarchies, then the complexity of building netfeaf has been decreased step by step, the whole building procedure becomes much easier, so oo method can really change complexity into simplicity
Netfeaf系統依據自頂向下、分而治之以及層層推進的實現原則，採用了全新的系統構造思路，對系統的集成用整體類庫組成圖進行表述，對各組成部分通過子類庫再進一步詳細介紹，系統的整體實現被一層一層分解、細化，各組成部分基於統一的計算核心集成在同一個系統框架內，同時相互之間還保持一定的獨立性，獨成一體，正是因為深入利用了面向對象的分析與實現手段，整個復雜系統構成從概念上更有利於理解，集成更加緊湊，具體模塊的實現也更加迅速高效，面向對象方法的變復雜為簡單的策略藝術在系統的具體實現過程中得到了充分展示。 -
The paper begins with the research of the organization ' s current state and available resource, then demonstrates the necessity and feasibility of system development, puts forward the objective and task of the system by the analysis of whole system, fixs on this system ' s main function and structure by the structured method of top - down and delicatilization step by step, and finally uses the object oriented programming to make the concrete design
本文從系統的現行狀態和可用資源的調查入手，論證了系統開發的必要性和可行性，通過對整個系統的分析，提出了系統的目標和任務，運用自頂向下、逐步細化的結構化方法確定了系統的主體功能和結構，最後運用面向對象的程序設計方法（ oop ）進行了具體的設計。 -
Nanometer pore arrays alumina films were prepared by anodizing of highly pure aluminum foils in sulfuric and oxalic acid solution. the porous alumina layers were detached from the al substrate by using step - down voltage or solution method
