新熱帶動物區The blade inner channel cooling is a complex convection - conduction coupling problem. this thesis build a three - dimension. compressible turbulence model, and give a general solve method. with the geometrical model of the glossily rectangle straight channel, the rectangle straight channel with in - line arrays disturb plates, the rectangle straight channel with staggered arrays disturb plates, the rectangle straight channel with slant disturb plates, this thesis compute the flow and heat transfer condition when the cold air path though these channels, and gain the temperature field, pressure field, velocity filed, in addition. this thesis also analyze the influence of the different channel height, the different channel materials, the different channels, and gain the function relation between he nusselt number, friction factor and reynolds number. this thesis is emphasis on the new heat transfer enhancement structure, that is, disturb plates, with the comparison with the glossily channel and channel with pin fins, the heat transfer enhancement effect of the former is better, and the conclusion can be used in the design of aircraft blade
葉片內部通道冷卻是一個復雜的對流?導熱耦合傳熱問題，本文在分析葉片內部通道冷卻的流動與傳熱情況的基礎上，建立了三維、可壓縮紊流的物理模型，得到了通用的求解辦法；利用不帶擾流片的矩形直通道、帶順排擾流片矩形直通道、帶叉排擾流片、帶傾斜擾流片的矩形直通道的幾何模型，計算了冷卻空氣通過這幾種通道時的流動與換熱情況，得到了各種不同情況下計算區域的溫度場、壓力場、速度場；在此基礎上分析了不同的通道高度、不同的葉片通道材質對葉片內部通道冷卻的影響，並整理得到了各種通道形式下，努謝爾數和阻力因子與雷諾數的函數關系；本文重點研究了新型的葉片內部通道冷卻強化傳熱措施?帶擾流片的內部冷卻通道的強化傳熱效果，通過與光滑矩形直通道、帶針肋通道的冷卻效果的比較，表明了這種新型鮚構的優勢，對于葉片內部通道冷卻結構的設計可以起到指導的作用。The distribution of all the genera and species ( including new taxa and new data by present research ) of the world are summarized, according to the history of continental drift and the result shows that empoascini originated in the oriental region in pangaea 145maago. zoogeographical analysis of all the taxa in china shows that most of the genera and species of empoascini are distributed in the oriental region, which is identical with the geographical distribution worldwide, i. e. most taxa distribute in the tropical and subtropical zone. phylogenetic analysis of 40 chinese genera of empoascini with one outgroupikranewa is presented in this paper
在生物地理及區系方面，總結了世界已報道及本研究新發現單元共計88屬1183種在世界各大動物地理區的分佈情況，結合大陸漂移學說的有關知識，認為小綠葉蟬族應起源於東洋區，起源時間在聯合古陸時期（約145ma以前） ；分析了中國已報道及本文新發現該族共40屬263種在中國動物地理區劃的歸屬，結果表明，中國小綠葉蟬族的種類分佈以東洋區占優勢，明顯多於古北區，這與世界該族昆蟲大多分佈於熱帶、亞熱帶的結果相一致。Researchers from conservation international and the indonesia institute of science had previously discovered several new species of plants and animals during a trip to the pristine rain forest region in 2005
國際保護生物性多樣性學會和印尼自然科學學會的研究員們先前已經於2005年在原始熱帶雨林區的一次科考中，發現了幾種新的動植物品種分享友人
