Standard lamp and diffusers are very important calibration elements , in chapter three , first uv and vuv radiometric standard for calibration are introduced . then the fabrication and characteristics of baso4 diffuser and alminium diffuser are researched , the baso4 diffuser ' s hemispheric reflectance and bi - directional reflectance distribution function were measured and compared with lambtian surface , and the deviation from that of lambtian surface is given . in the experiment , al diffuser ' s brdf is researched , obtain the change of spectral characteristic of al diffuser , compare al diffuser ' s brdf before and after coated with al + mgf2 , and different al diffusers with different surface roughness 鋁漫反射板作為一個漫反射光學元件安裝在太陽紫外光譜監視器的入射狹縫前,太陽紫外光譜監視器在軌測量時,太陽輻射入射到鋁漫反射板后進入入射狹縫,光譜輻照度的角度是變化的,本章測量了鋁漫反射的相對雙向反射分布函數,研究了鍍膜( al + mgf _ 2 )前后光譜反射率的變化,漫反射的光譜特性及漫反射板表面粗糙度對相對雙向反射分布函數的影響,使得測量數據反演成為可能。

First , the apparatus of spectral irradiance calibration is set up , and ultraviolet spectrum band uses a standard lamp offered by standard metrological institute of china , while vacuum ultraviolet spectrum uses a deuterium transfer lamp 地面輻射定標分為光譜輻照度定標和光譜輻亮度定標。光譜輻照度定標中選用了鹵鎢燈作為250nm 400nm標準光源,氘燈作為200nm 300nm的傳遞光源。

Full of ancient special features , the beauty is practical , is the comprehensive body that the art object adds a standard lamp to add clock , the quality is best , the price is reasonable , welcoming to telephone to consult or want sample 富有古代特色,美觀實用,是藝術品加臺燈加時鐘的綜合體,質量上乘,價格合理,歡迎來電咨詢或索樣!

He offered me the choice of any one of these for a wedding present : a set of fish knives , a teapot , an electric toaster , and a standard lamp 他提供這些東西讓我挑一樣作為結婚禮物:一套魚刀,一把茶壺,一個電烤箱,一盞落地燈。

Custom metal deer lamp stands 35 inches with a standard lamp shade and wood base . any style available made to your order 定制金屬燈鹿身高35英寸與標燈綠蔭和木材基地.任何風格提供了你的命令

That standard lamp is a real white elephant - it doesn ' t work and it doesn ' t go with the rest of the furniture 那臺落地臺燈真是個累贅- -它不好使,而且跟別的家具不相配。
