中文拼音 [jírèqìchǐcùn]
集熱器尺寸
英文
collector size-
In the selective calculation module, the calculations of heat exchanger design, the analysis of pipe setting patterns are combined with the database so that the selective calculation sub - system is developed. considering the factors such as uniform flowing of the fluid, smaller inner radius of the shell, the well heat exchanging effect and saving materials, the pipe setting module is developed based on the designing data. in the module for automatically generating parts and assembly drawings, the database of pattern sizes and the drawing libraries are established according to the classifications and series
在選型計算模塊中，通過換熱器設計計算、管束組件的布管方式分析、數據庫的檢索，開發了浮頭式換熱器輔助設計計運算元系統；在布管定型模塊中，按照確保殼程流體流動均勻、且換熱器殼體的內徑較小、管程殼程間換熱良好且節省材料的原則，根據設計計算參數建立了自動布管定型系統；在零部件圖和裝配圖自動生成模塊中，分級分類地開發了浮頭式換熱器所有零部件圖和裝配圖的圖紙尺寸數據庫和圖庫，運用「死圖活尺寸」的開發理念，開發了圖形自動生成與管束參數化設計的集成系統。As composite material are widely used in navigation and physical education equipments for high comparing intensity and module, even it has the approxi - mate zero expanding coefficient, as the same time, configuration of composite has been aroused attention by scientific researchers, the goal of them is to find an integrated structure with high efficiency and intelligent and many function all along. grid structure is the right structure with the high efficiency, the researchers overseas have been studying the structure for many years, which manifests it has many excellent nature ; existing research indicate it has higher stiffness and intensity. the form can be detected in health easily for its open shape
復合材料具有高的比強度和比模量，同時又具有近於零的熱膨脹系數和良好的尺寸穩定性等優良性能，已經廣泛應用於航天航空事業和體育器材生產工業，與此同時，尋求一種高效的、低成本的、並將智能化和功能化集於一體的結構形式，一直是航空航天追求的目標，具有點陣結構的復合材料格柵結構正是這種高效的結構形式，表現出多項優良性能;國外對其進行了大規模的理論分析和一些數值模擬研究，已有的研究表明該結構具有良好的可設計與自動化生產性能而無材料之間匹配問題，開放式的結構形式為結構的健康檢測提供了便利，具有廣闊的應用前景。First, the scaling limitation and relative reliability problems are analyzed for mosfet in vlsi, especially for hot - carrier effects of small dimension mosfet. and a review of the study of hot - carrier effects on devices and circuits is presented
