位於賽嘉的航空園區，座落在一個小山頭上，視野遼闊，和下方平坦的河川地著陸區之間，約有三百公尺的高度落差，加上此地上升氣流旺盛，是國內最佳的航空運動場地，每逢假日，飛行高手匯聚，十分熱鬧。For 2h, the osc and special surface area decreased sharply, meaning a bad thermal stability. the osc and special surface area of the samples prepared by precipitation keep very well after aged, exhibiting a promising thermal resistance. while the samples prepared by dipping method have a much more stable osc at different temperature, that is, they have a good thermal stability
研究表明，採用溶膠?凝膠法制備的樣品在老化前具有最大的儲氧量和比表面積，但經高溫老化后，其儲氧量急劇下降，表現出很差的抗高溫老化性能；採用沉澱法制備的樣品在老化前後，其儲氧量和比表面積降幅最小，有良好的高溫熱穩定性能；採用浸漬法制備的樣品不管老化與否，其儲氧量並不隨著儲氧溫度的改變而大起大落，表現出較好的熱穩定性。Postmodernist perspective of student thinks, student is the creative being, education should esteem student ' s creation, develop student " creative potential, protect student ' s creative ardor, develop student ' s creative ability, the highest idea of quality education is to develop student ' s creative ardor and student ' s practical ability, student is original being, education should esteem student ' s multi - aspect differences, remove all kinds of discrimination, listen to different voices, especially, the voice of disadvantageous groups, concerns students on minor status or the edge ; student should become sustainable developmental human, education is an enterprise to develop human ' s potential
后現代主義學生觀認為：學生是創造性的存在物，教育應尊重學生的創造，開發學生的創造潛能，保護學生的創造熱情，發展學生的創造能力，素質教育的最高理想是培養學生的創造熱情和實踐能力；學生是獨特性的存在物，教育應尊重學生的多方面差異，要清除教育中的各種歧視，主張傾聽不同聲音，特別是弱勢群體的聲音，要關注處在次要或邊緣地位的學生（如落困生、少數民族學生、殘疾青少年等等） ；學生應該成為可持續發展的人。教育是開發人的潛能的事業。Results show that the brittle fracture is mainly caused by hydrogen brittleness that results from the oxidation arid absorbing hydrogen of copper tube during braze welding
同時在加熱和冷卻時，由於異種材料的熱脹系數差別過大，產生的較大熱應力作用於已存在的裂紋，促使裂紋二次擴展，甚至使得晶粒脫落產生空洞，最終導致焊接接頭漏氣失效。The growth of the consumption demands has been suppressed by the lower wealth, the uncertain future income and future cost, the backward fundamental facilities of the countries and the slowly growing income of the peasants ; because the transformation investments grows too slowly, the propulsion of the political investments is weak, the growth of the spontaneous investments is feeble and the zeal for the foreign businessmen go to guangxi to invest is not intense, the growth of the investment demands is slow ; the great many of deficits worsen the situation of the domestic and foreign trade and cut down the demands to the products and services of guangxi seriously
此外，還分別在消費、投資及內外貿易等方面探討了需求不足的原因。比如財富水平低、預期收入及支出的不確定性以及農村基礎設施落後及農民收入增長緩慢等，抑制了消費需求的增長；又如更新改造投資增長乏力、政策性投資帶動力不強、自主投資增長不力以及外商投資熱情不高等，抑制了投資需求的增長；再如巨大對內貿逆差惡化了內外貿易狀況，嚴重降低了對廣西產品和服務的總需求。Based on the j c chen double mechanisms superposition model, the experimental formula of the heat transfer coefficient on the evaporation side in the smooth tube was obtained. considering the influence of spring to the falling film, the formula of heat transfer coefficient on the evaporation side in the vertical tube with spring inserts was obtained. the predicated heat transfer coefficient through this two formulas was finely accord with the experimental result, and the error was basically under 10 %
在jcchen雙機理加和模型的基礎上，得出了光管降膜蒸發側傳熱系數的實驗關聯式，並考慮了螺旋線對降落液膜的影響，得出了管內插入螺旋線的降膜蒸發側傳熱系數關聯式，這兩個關聯式預測的傳熱系數與實驗值吻合良好，誤差基本在10以內。分享友人
