absorptance

基本解釋

A beam ethereal, sullied, and absorpt!
在虛無與神聖的中間！
The solar absorptance changed obviously,while the emittance has little change after irradiation.
材料輻照後太陽吸收率發(fā)生明顯變化,而輻射率幾乎不發(fā)生變化。
With increased irradiation time,the surface roughness and solar absorptance are increased.
隨著輻照時間的增長,材料表麪粗糙度增加,導(dǎo)致太陽吸收率增大。

Finally, we have studied the effect of the variation of absorptance and the distribution of incident energy density on the relevant process.
對於吸收率的變化與脈沖激光能量密度的分佈對於相應(yīng)過程的影響 ;進(jìn)行了分析討論 .

a measure of the ability of an object to absorb radiation, equal to the ratio of the absorbed radiant flux to the incident flux. For a layer of material the ratio of the flux absorbed between the entry and exit surfaces of the layer to the flux leaving the entry surface is the internal absorptance ( symbol: ) &rarrcompare reflectance , transmittance

吸收比
In this way the thickness of Al2O3 films measured is 50nm,with the absorptance of either visible light or sunlight approximates to zero.
測試得到50 nm厚的Al2O3薄膜,其可見光吸收比和太陽光吸收比接近零。
