Continuous monitoring of the solar irradiance have been carried out since the early 80s by instrument in space . this is essential because several portions of the solar radiation spectrum such as ultraviolet and far infrared are blocked by earth s atmosphere 自八十年代初，科学家已使用太空仪器不断监察太阳的辐射度要在太空作观测，是由于部分太阳光谱如紫外线和远红外线等并不能穿过地球大气。
( 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 研究了镝灯光谱相对能量分布，首先根据a级模拟器提供的带宽和带数对镝灯的光谱能量分布进行了测试，测试结果表明，利用镝灯来模拟太阳光谱达不到a级模拟器的要求；根据b级模拟器提供的带宽和带数对镝灯再次进行测试，并与b级的光谱失配误差进行比较，结果表明，利用镝灯来模拟太阳光谱可达到b级模拟器标准。
Some preliminary conclusions of making better image quality are obtained by observing some effects of climate conditions on quality of solar image during spectral observations . they are : ( 1 ) quality of imaging to be better when the wind stops or weaken suddenly during the wind blows continuously ; ( 2 ) if the wind blows at the whole night and it is fine day in the next morning , then the image quality will be better than before . ( 3 ) the image quality is getting fine in short time after the cloudy . ( 4 ) the good solar image to be formed under the condition of a beginning of fine day after the cloudy or raining days 在多年的太阳光谱观测中，通过观察各种天气条件的变化对光谱仪成像质量的影响，初步总结出使像质优良的几条规律： 1 )在连续刮风过程中当风突然停止或减弱的短暂时间内像质明显变好； 2 )当夜间通宵有风而次日天气晴朗时像质变好； 3 )多云过后的短暂晴天成像优良； 4 )接连阴雨几天后的开始晴天像质较好。
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 摘要为了研究抛物面碟形聚光器实现太阳能直接抽运光纤激光器，根据空间太阳光谱分布特点，采用数值方法，计算了用该聚光器聚集太阳能量抽运双包层光纤激光器时光纤吸收的太阳能量及其吸收效率。
The durations of good imaging within a fixed year are preliminarily obtained by statistical analysis of imaging quality obtained from spectral observations in 1982 with the horizontal spectrograph installed at the yunnan observatory . the results show that in the autumn , september and august , a good image is usually available . for a daytime , there are two time intervals during which the solar image is relatively better than other time , one is in the morning 2 3 hours after the sunrise ; another in the afternoon 3 4 hours before the sunset , and it lasts about 0 . 5 1 . 0 hours for each 通过对云台水平式太阳光谱仪1982年太阳光谱观测中的成像质量情况统计分析，初步得到光谱仪一年中成像质量优良的时间在秋夏9月和8月份；一天内有两次像质优良的时间，上、下午各有一次，分别在日出后2 3小时和日落前3 4小时各有半小时到1小时左右的时间。
