本文試圖從膨脹劑不同摻量研究其對混凝土和砂漿主要性能的影響，進行了一系列宏觀力學性能試驗研究；利用差熱分析（ dta ） 、掃描電子顯微鏡（ sem ）等分析手段對鈣礬石等水化產物的結晶和生成量、形貌特徵進行微觀分析；並採用復合方法摻加新型膨脹組分對硫鋁酸鹽類膨脹劑（ uea ）進行了改性試驗研究，根據多因素模糊綜合評價方法就各類膨脹劑的主要性能進行綜合評價，得出摻加新型膨脹組分pt的膨脹劑性能較優，取得了明顯的效果。Abstract : there are offered many ways how to improve work of a spark plug. but one of the m ost important problems has not been solved yet. this is a thermal mode operation of a spark plug. the ideal spark plug should be instantly heated at the moment of occurrence of a spark and instantly cooled down in expectation of the foll owing electrical pulse. thus it balances between preservation of heat for self ? c leaning from scale and its removal in avoidance self ? ignition. in this article a uthor managed for this time to offer a spark plug with capability “ self ? regula tion ” of heat flux removed from a zone of ignition. essence of the offer is a t ip ， which is transparent for heat flux. it is produced from single crystal of sap phire
文摘:在如何提高火花塞的工作質量方面有多種方法，但是其中最重要的一個問題還沒有得到解決，那就是火花塞工作的熱學模型問題.理想的火花塞應該能在點火的瞬間被立刻加熱，並且在接下來的電脈沖過程中迅速冷卻，由此在熱量的存儲與散發之間取得平衡，以避免自點火.本文力圖展示一種具有自動調節源於點火區域熱流能力的火花塞，其技術的關鍵是頂部絕緣體材料，它是由藍寶石單晶製作，而非傳統的氧化鋁陶瓷Abstract : in this study, 2618 aluminum alloy manufactured by spray process was heated in a heating furnace, and the microstructures were investigated. by the process of heating in a heating furnace and then squeeze - forming, one component of the motorcycle was produced successfully with the semi - solid aluminum alloy
文摘:採用電阻爐加熱的方法對噴射沉積法制備的2618鋁合金進行了二次加熱實驗，觀察了顯微組織的變化；並通過電阻爐加熱、半固態擠壓鑄造的方法成功地試制了摩托車零件。Test method of accelerated life of iron - chromium - aluminum alloys for electrical heating
