arc melting method 中文意思是什麼
arc melting method
解釋
電弧熔煉法-
The single fiber sensor head was investigated experimentally and theoretically. two kinds of sensor head fabrication methods were demonstrated and compared, which are the electrical arc melting and mechanical grinding respectively. a mathematic model of fiber tip reflection was established by the method of ray - tracing
論文提出並比較了兩種製作單光纖傳感頭的方法：電弧拉製法和光纖研磨法；利用光線追跡法建造了單光纖傳感頭的數學模型。 -
The results indicate that arc melting is a good method to produce nb - si system intermetallics due to its simpler technics, lower cost and compact products. however, powder metallurgy is found to be not suitable to produce the nb - si system intermetallics due to its coarse and loose products resulting from the poor molding property of nb and si mixed powders. optical floating zone technology, which is used to fabricate nb - si intermetallic composites for the first time, is also found to be a good way to produce nb - si system intermetallics because of its compact products and good property despite of its relatively high cost
結果表明，電弧熔煉方法制備得到的nb - si系金屬間化合物比較緻密，且制備工藝簡單，經濟實用，是一種合適的nb - si系金屬間化合物制備方法；由於nb 、 si元素粉末的成型性很差，用粉末冶金方法（熱壓燒結和冷等靜壓）制備的nb - si系金屬間化合物表面粗糙、緻密度低，且成本較高，不宜用於制備nb - si系金屬間化合物；首次用光學懸浮單晶生長技術制備的nb - si系金屬間化合物復合材料緻密度很高，盡管成本稍高，但由於性能最佳，也是一種合適的nb - si系金屬間化合物制備方法。 -
The single - slag steel melting method affected by the main process parameter of arc furnace
電弧爐主要工藝參數對單渣法煉鋼的影響 -
The thesis apply a method of genetic algorithm which is combined with sweden arc method to program to calculate, and regard destroying of beiyin edge slope during freezing - melting eroding as important destroying factors. above two points are the emphases and breakout point
本文在邊坡穩定分析中利用遺傳演算法與瑞典圓弧法相結合，進行編程計算，並且把凍融侵蝕對北引渠道的邊坡破壞作為重要的破壞因素進行分析研究，以上兩點是本文的重點和突破點。
