難熔玻璃 的英文怎麼說
中文拼音 [nánróngbōlí]
難熔玻璃
英文
high melting glass-
It is found that the chemical durability of na2o4teo2 glass is dominated by the humidity of the surrounding air during the processes of glass melting and the following cooling. the mystery that na2o4teo2 glass crystallizes after drop shaft experiment, which has puzzled glass researchers for many years, is solved. this work indicates a way for making na2o4teo2 glass with good chemical durability
此反應主要受玻璃在熔化和冷卻過程中的環境濕度控制,存放過程中的空氣濕度對它也有影響,這解決了困惑人們多年的落塔實驗中na _ 2o ? 4teo _ 2玻璃析晶的問題和na _ 2o ? 4teo _ 2玻璃穩定性難以控制的問題,為制備空氣中穩定的na _ 2o ? 4teo _ 2玻璃提供了明確的依據。A sil flying head is designed to keep the distance between sil and recording medium in near - field range. a sil optical data storage system is built up when the recording head is combined with sil flying head. meanwhile, using astigmatic focusing error detection technology and twin optical pick - up heads, a novel nontouching nanometer measurement method is developed to measure the flying height of sil, and provides us with a powerful tool to optimize the design of sil fly head
在sil存儲技術研究方面,首先提出一種光學玻璃熱熔加工製作sil的新方法,該方法克服了小半徑球透鏡加工的難題,成功製作出了半球固體浸沒透鏡;設計了sil飛行頭系統,並利用光學頭像散法聚焦誤差檢測原理,設計出一種雙光學頭sil飛行高度測量方案,實現了sil飛行頭飛行高度的測量。It is a dozen metals in one ; now almost diamond - hard - - and again almost as soft as copper ; here brittle as glass ? there malleable1o as silver ; now welding quite readily - - again, very difficult to weld ; melting rather easily - - at other times difficult to diffuse ; usually very magnetic - - and : again almost non - magnetic ; an excellent conductor of heat and electricity - - and at times stubbornly resistant to both
鐵將十多種金屬特性合而為一:時而幾乎堅硬如金剛石,時而又柔軟如銅;此處易碎如玻璃,彼處又可展延如銀;時而很容易焊接,時而又很難焊合;有時相當易熔,有時又極難擴散;通常情況下富有磁性,但有時又幾乎磁性全無;本是熱和電的優良導體,但有時卻頑強地抗拒二者。Mainly produce the refractory metal materials including wolfram, molybdenum, tantalum, zirconium, niobium, titanium, nickel and the products ; we undertake the manufacture of the compound materials like titanium, nickel, molybdenum, zirconium stainless steel and the vessels, fasteners, titanium basket, titanium panel, etc. our products are extensively applied in many fields like petrol - chemical, chemical fiber, electronics, electric light source, electric vacuum, fertilizer, pharmaceuticals, glass fiber, electrical medium and galvanization, etc
