The earth s climatic changes show regular periodicities on the time scale of 10～100 ka, which are controlled by orbitally modulated variations in insolation and which can be calculated with great precision for several Ma.
地球气候变化在 10～ 10 0ka (千年 )的时间尺度上表现出规则的周期性 ,它们主要受轨道日射变化控制 ,并能被很精确地计算到几百万年 。
In this paper,the ITE of TBQ 2 pyranometer,as an example,is calculated.
对双层球形玻璃罩的增透作用进行理论分析，以ＴＢＱ－２型总日射表为例进行计算，其外罩有效透过率的计算结果与实测结果相近。
In this article, the calibration method of spectral pyranometers is discussed in detail.
详细讨论了分光总日射表的校准方法。
Based on GMS data of cloud amount during 1992—1994,the distribution of solar energy resource over Tibet region were studied with the help of the non linear relationship between cloud amount and percentage of sunshine and the linear relationship between the later and global radiation Mean while the distributions were corrected through the comparison between cloud amount of 1992—1994 and normal
利用１９９２—１９９４年从日本静止气象卫星提取的云量资料，借助云量与日照百分率之间的非线性关系以及后者与总日射间的线性关系，对西藏地区的太阳能资源分布进行了计算研究，并绘制了１９９２—１９９４年的太阳能资源图。
