finned ratio-
The heat - exchange apparatus is the window for air - conditioner to exchange energy with outside. we analyze the efficiency of heat - exchange apparatus by the theory of heat - transmit, and compare the advantage and disadvantage of different type evaporator ' s and condenser ' s design by lots testing, and compare the effect of heat - exchange for different type flake, and compare the effect of heat resistance for different stretch of copper tube and flake. then we get many useful results from those different comparing
蒸發器與冷凝器統稱為換熱器，換熱器是空調器與外界進行能量交換窗口，利用傳熱學原理對換熱器的效率進行分析，通過大量的試驗比較不同的蒸發器，冷凝器設計方案的優劣；比較冷凝器使用不同片型對換熱效果的影響；比較銅管與翅片的不同脹緊對熱阻的影響，通過比較得出很多有用的結論。In practice, changing the belt wavelength, comparing the heat transfer performance of the single row tube and single wave belt with the single row tube and double waves belt, double row tubes and double waves belt, three row tubes and single wave belt, i draw a conclusion that the single row tube and double waves belt is the best
在實踐上，通過改變翅片波距w ，比較單排單波帶、單排雙波帶、雙排雙波帶及三排單波帶散熱器的傳熱性能，得到單排雙波帶傳熱效果最佳的結論。These methods are following : ( 1 ) in order to build fem model conveniently and enhance calculating speed, interceped a finite length and built a 2d - symmetry model. ( 2 ) in order to apply loads conveniently, kept the entrance of cold fluid. ( 3 ) in order to obtain numerical results in steady situation, lengthened export and import ends
這些方法主要有： （ 1 ）為了便於建立模型並提高計算速度，對于實際工程中採用的長徑比特別大的換熱管採取截取有限長度的方法並建立二維對稱簡化模型； （ 2 ）提出採取保留冷流體入口端，截取有限長度的方法施加載荷； （ 3 ）適當延長翅片管的出口端和入口端，以便獲得穩定工況的數值解。The different organs of elaeagnus mollis diels were used in this experiment as the explants. after establishing the aseptic propagation system, the aseptic tube stems and leaves were used to study the effect of different exogenous hormones combination and different culture conditions on organgenesis. the optimum medium and culture condition was screened for fast propagation of elaeagnus mollis diels
本實驗選材為胡頹子科胡頹子屬的翅果油樹，在建立起無菌繁殖系的基礎上，分別以試管無菌莖段和葉片為材料，研究了不同外源激素配比及不同培養條件對其器官分化的影響，從中篩選出適合翅果油樹快速繁殖的最適培養基和培養條件。分享友人
