fused quartz 熔凝石英,熔凝水晶。

fused salt

The photocatalytic activity of the samples was evaluated by the photocatalytic oxidation of nitrogen monoxide in the gaseous phase and the photocatalytic decolorization of methyl orange solution in the aqueous phase , respectively . the titania thin films on fused quartz were prepared by lpd method and then calcined at different temperatures 用液相沉積法在石英玻璃上制備了二氧化鈦薄膜,并在不同的溫度下進行熱處理,用甲基橙水溶液的降解脫色評價二氧化鈦薄膜的光催化活性。

2 . the optical transmission spectra of batio3 thin films annealed at different temperatures on fused quartz substrates are measured . the bandgap energies calculated from their optical transmission spectra are larger than that of single crystals reported in the literatures , whereas for poor - crystallized films with lower annealing temperature , their bandgap energy values are much larger than that of single crystals 發現batio3多晶薄膜的光學帶隙大于文獻報導的單晶薄膜的光學帶隙,對于結晶性好的薄膜,其光學帶隙接近于單晶值,退火溫度越低,結晶性越差,與單晶的光學帶隙相差越大。

The prototype is made by a concave sphere primary and a plane secondary deposited the mo / si multilayer on the fused quartz substrates . the reflectivity peak and the reflectivity uniformity of the multilayer mirrors are respectively 25 % and around + 2 . 5 % at 17 . 1nm 望遠鏡主鏡為球面,次鏡為平面,所用反射鏡為在熔石英基底上鍍制mo si多層膜的euv波段反射鏡,在17 . 1nm的反射率25 ,反射率的均勻性2 . 5 。

These ping pong - sized balls of fused quartz and silicon are 3 . 8 cm across and never vary from a perfect sphere by more than 40 atomic layers 這些如乒乓球般大小,以石英和硅融合而成的球體直徑約3 . 8厘米,偏離完美球體的程度不會多于40層原子。
