oxidized layer 中文意思是什麼
oxidized layer
解釋
氧化層-
In this paper, micro - cavity semiconductor laser ( mcsl ) with pillar vertical - cavity surface - emitting structure ( vcsel ) which has potential applications in optical communication and optical interconnect is theoretically analyzed, the calculation model that used to discuss the modal performance of rectangular columnar and cylinder vcsel with oxidized aperture is established by using vector field model. the numerical simulations in the case of cylinder structure show oscillating wavelength and threshold gain against inside and outside radius of laser, the layer refractive index and pair number of bragg mirror, thickness, position and oxidized material ' s refractive index of oxidized aperture, in detail. more practically, considering dos shell of laser as non - perfect one, or supposing that dos shell is separated from the laser, we can obtain more significative results
本工作以矢量場模型出發，對具有誘人應用前景的柱形垂直腔面發射結構（ vcsel ）的微腔半導體激光器（ mcsl ）進行了理論分析，建立了用於分析方柱形和圓柱形結構具有氧化孔徑層的激光器的模式特性的理論模型；對圓柱形結構情況進行了數值模擬，得到了振蕩波長、閾值增益隨激光器內外半徑、 bragg反射鏡層折射率、周期數以及氧化孔徑層厚度、位置和氧化物折射率的詳細變化規律；為使理論計算更接近實際，將外加金屬包殼視為非理想導體，或將金屬包殼與激光器結構隔開，分別對這兩種情況下的結果進行了討論。 -
The results show that a solid self - healing anti - oxidation protective layer will form over the surface of composites when oxidized at 1100 ~ 1200 ; and when oxidized at temperature of 1300, the self - healing protective layer will change into liquid state or semi - liquid state and the anti - oxidation property of the composites will get worse
結果表明：復合材料在1100 、 1200氧化時表面會生成固態自愈合抗氧化保護膜，該層保護膜的生成可以阻止復合材料繼續被氧化；而當復合材料在1300下氧化時生成的自愈合保護膜呈液態，此時復合材料的抗氧化性能變差。 -
For the special physical and chemical character of aluminum, a nickel layer is deposited before electroplating. it can avoid the active surface of aluminum oxidized again or substitution reaction in the bath
由於鋁特殊的物化性質，電鍍鎳鉻合金前採用預鍍鎳的工藝，避免活化后的鋁基體表面再次被氧化或在鍍液中發生置換反應。
