真空塗覆 例句

1. The film is deposited on the surface of the glass by evaporating crystals, usually of cryolite or magnesium fluoride, in a vacuum.
   塗 敷薄膜時，通常是將玻璃置於 真 空 之中，然後使冰晶石或氧化鎂晶體氣化，令其沉積于玻璃表面上。
2. Because of the restriction of the performances of the infrared materials, we decide that the hollow waveguide should have the structure of single layer dielectric coated metallic film according to the general analysis of process controllability and transmission capability. the dielectric we choose is silver iodide, made from silver and iodine, and the optimum thickness is about 0. 77um
   因材料性能的限制，通過傳輸性能以及工藝可控性綜合分析，確定製備的 空 芯光纖為單層電介質 塗 覆 金屬膜結構，電介質膜定為碘化銀，理論厚度為0 . 77 m左右，由銀膜直接碘化得到。
3. Vacuum distillation of solvents from solvent - reducible paints for analysis
   從溶劑稀釋 塗 料中 真 空 蒸餾出分析用溶劑的方法
4. At the initial stage of planar technique, b was employed as ideal diffusion impurity in base - region of npn si planar devices because of the match of its solid - solubility and diffusion coefficient in si with those of p in emission - region, and the good shield effect of sio2 film to b. but because of the relatively large solubility ( 5 1020 / cm3 at 1000 ) and the small diffusion coefficient, the linear slowly - changed distribution of acceptor b in pn junction can not be formed, which could not cater to the requirement of high - reversal - voltage devics. thereafter b - a1 paste - layer diffusion technology and close - tube ga - diffusion technology had been developed, while the former can lead to relatively large the base - region deviation and abruptly varied region in si, which caused severe decentralization of current amplification parameter, bad thermal stability and high tr ; the latter needed the relatively difficult pack technique, with poor repeatability, high rejection ratio, and poor diffusion quality and productio n efficiency
   在平面工藝初期，由於b在硅中的固溶度、擴散系數與n型發射區的磷相匹配， sio _ 2對其又有良好的掩蔽作用，早被選為npn硅平面器件的理想基區擴散源，但b在硅中的固溶度大（ 1000時達到5 10 ~ （ 20 ） ，擴散系數小， b在硅中的雜質分佈不易形成pn結中雜質的線性緩變分佈，導致器件不能滿足高反壓的要求，隨之又出現了硼鋁 塗 層擴散工藝和閉管擴鎵工藝，前者會引起較大的基區偏差，雜質在硅內存在突變區域，導致放大系數分散嚴重，下降時間t _ f值較高，熱穩定性差；後者需要難度較大的 真 空 封管技術，工藝重復性差，報廢率高，在擴散質量、生產效率諸方面均不能令人滿意。
5. A vacuum carbonized furnace which manufactured to carbonize straw pole, a set of equipment which globe - grinded the carbonized straw pole were designed and prepared in this work. the furnaces were used to carbonize the smashed straw pole in the vacuum furnace first, and to grinded it in the globe - grinding machine. with the powder, woodceramics target and compound target were made to manufacture external metal - carbon wave - guide compound film series on columned ferrite surfaces
   在本論文工作中，自行設計與製造了制備碳化秸稈的 真 空 碳化爐及粉碎球磨設備，用此設備把粉碎的秸稈先在 真 空 碳化爐中進行碳化，碳化的秸稈粉再經過球磨設備球磨成細粉，用此細粉做成木質陶瓷靶和復合靶材在圓柱鋰鐵氧體表面鍍 覆 符合要求的表面金屬-碳系復合波導膜，並制備了木質陶瓷 塗 層導電膜。
