solar spectrum 太陽光譜。

solar time

To investigate the practicability of a solar - direct - pumped fiber laser by using a parabolic dish concentrator , the solar power absorbed by the fiber laser and its absorption efficiency were calculated with numerical method based on the characteristics of solar spectrum in outer space 摘要為了研究拋物面碟形聚光器實現太陽能直接抽運光纖激光器,根據空間太陽光譜分布特點,采用數值方法,計算了用該聚光器聚集太陽能量抽運雙包層光纖激光器時光纖吸收的太陽能量及其吸收效率。

( 3 ) in the dy - lamp experiments , we study the spectrum distribution of relative - energy . firstly , it is tested by providing bandwidth and the numbers of the band according as a standard of the solar simulator . the result shows it cannot achieve a standard of the solar simulator that the spectrum distribution of the dy - lamp is simulated the solar spectrum ; however , if according as b standard , then it can attain the request of b standard of the solar simulator 研究了鏑燈光譜相對能量分布,首先根據a級模擬器提供的帶寬和帶數對鏑燈的光譜能量分布進行了測試,測試結果表明,利用鏑燈來模擬太陽光譜達不到a級模擬器的要求;根據b級模擬器提供的帶寬和帶數對鏑燈再次進行測試,并與b級的光譜失配誤差進行比較,結果表明,利用鏑燈來模擬太陽光譜可達到b級模擬器標準。

Fig . 3 and fig . 4 show that grooves in the width of 1 - 2micrometer on the surface of films sputtered at 180 forms optic trap of solar spectrum in the range of 0 . 25 ~ 3micromete , and increase the absorption efficiency of solar radiation 在溫度約180的情況下的薄膜表面形貌,薄膜表面寬度為一兩個微米溝槽,形成了對0 . 25 ~ 3微米太陽光譜的光學陷阱,可提高太陽光譜范圍能量的吸收率。

Black tin coating was prepared by multi - arc ion plating technology , and wear resistance , corrosion resistance , heat - proof property and absorption property of solar spectrum were also discussed 摘要介紹了利用多弧離子鍍工藝制備黑色氮鈦膜,并對其耐磨損、耐腐蝕、熱穩定性及太陽光譜吸收等性能進行了研究。

The purpose studying the paper is to looking for a sort of the lamp - house , which used to simulate solar radiation and the distribution of relative - energy on solar spectrum 本文研究的目的就是尋求一種合適的光源對太陽輻射和太陽光譜相對能量分布進行模擬。
