漫射輻射能 的英文怎麼說
中文拼音 [mànshèfúshènéng]
漫射輻射能
英文
stray radiant energy-
Sudden bursts of solar radiation can kill an unprotected spacewalker
一陣來自太陽的輻射可能奪去一個沒有保護的太空漫步者的生命。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佈函數,研究了鍍膜( al + mgf _ 2 )前後光譜反射率的變化,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佈函數的影響,使得測量數據反演成為可能。For example, light emits from the surface of a typical main sequence star falls mainly in the optical window. that is why we can see our sun in daytime and countless stars at nighttime
例如,大部分主序星表面發射出來的輻射是可見光,因此我們能夠在日間看見太陽,夜間看到漫天星斗。
