To the influence of the plateau terrain , the impact of the elevation and the roughness of terrain to every energy component out and incoming are study , and basing the soil spectrum model proposed above , a new radiative transfer model of terrain area was put forwarded in which the soil water content , lai , terrain roughness and elevation were considered synchronously , and incoming scatter light was integral with the solid angle of semi - globe space defined by the slope of the pixel , so scattering lights of terrain and the sky are properly considered , but the operation is still within the acceptable range 地形與反射率的關系是本文研究的一個重點。本文對崎嶇山地象元的各入射光和反(散)射光分量進行了深入分析,在所提出的濕潤土壤光譜模型和植被冠層模型的基礎之上進一步提出了新的適合青藏高原的山地輻射傳輸模型。該模型同時考慮了土壤含水量、植被覆蓋( lai ) 、地形起伏和海拔高度的影響,并以象元坡面定義的半球空間立體角對環境入射光進行積分,使周圍地形和天空散射光均得到適當考慮,計算量又在可接受范圍內。

The function of illumination optics for projection displays is to direct light source onto a small area of microdisplay within a limited incident solid angle , and therefore the collection efficiency is especially important compared to other illumination applications , which is also the main technical issue for led application to projection displays 摘要投影顯示之照明系統須將光能量集中照明于一小面積與小角度之內,相較于其他照明之應用,其集光效率之考量更為嚴苛,亦為發光二極體于投影顯示照明應用中最主要之技術課題。

For liquid xe aerosol spray target , important lpp characteristics , such as laser - to - euv conversion efficiency , euv radiation absorption , debris production by target material erosion or deposition , are studied in detail , a 13 . 4nm conversion efficiency of 0 . 75 % into 2 % bandwidth and 2 steradian emission solid angle is achieved at 0 . 5mm laser - nozzle distance 在實驗上,建成了一套高光譜分辨率和高靈敏度的軟x射線脈沖輻射測量裝置。測量了co _ 2 、 o _ 2 、 cf _ 4 、 kr和xe液體微滴噴射靶lpp光源在6 20nm波段的軟x射線輻射光譜。

The equation of the radiation transfer between two surfaces indicates that there are three factors that have influence on radiation transfer : brdf , projected solid angle ( psa ) , and incident radiation flux . thereafter , a new baffle system design idea is put forward 本文首先介紹了光學系統雜光的抑制措施,從光輻射在兩個表面傳遞的基本能量傳輸方程出發,指出影響輻射能量傳輸的三個因子:雙向反射分布系數brdf 、投影立體角psa和入射輻射通量。

The numerical results show that a reasonable reconstruction is also possible for low wavenumbers even when the incidence and observation aperture is as small as the possible / 4 solid angle 數值結果表明,對較小的波數,即使當入射和觀測孔徑為/ 4立體角時,得到一個合理的重構也是可能的。

The ratio of the flux emitted within the solid angle defined by the beam spread , to the bare lamp flux 由光束角限定的立體角內輻射出的光通量與裸光源光通量之比。

It covers geometrically 86 % of the 4t solid angle and has very low detection thresholds 整個探測器系統軸向對稱排列,工作在真空中。

The brightness or luminance of an object is defined as the luminous flux emitted per unit area of the object into unit solid angle . 物體的亮度或發光率定義為物體面積發射到單位立體角內的光通量。

The solid angle is this component divided by the square of the length of this line . 立體角就是這個分量除以這條線的長度的平方。
