We describe the newly updated multichannel infrared solar spectrograph at the Purple Mountain Observatory that now uses three Apogee AP7p grade 1 scientific CCDs as its detectors and works at three wavelengths,He I 10830A,Ca Ⅱ 8542A and Hα,simultaneously.The spectral resolutions of these lines are 0.04776,0.05113 and 0.05453A per pixel,respectively.Some observation examples are presented.the observed profiles of the three lines demonstrate that redshift and asymmetry exist in the impulsive phase of the given disc flare and both blueshift and redshift exist in the presented flare spray in the impulsive phase of a limb flare.They also indicate that horizaontal expansion exists in addition to the quick radial motion in the flare spray. 相似文献

辐射发热率是灰棒等堆内特殊材料性能研究、热工安全分析和力学分析的重要输入参数,因此堆内特殊材料的辐射发热率评估是新型堆内材料研究的重点内容之一。为了提高中子和光子辐射发热率的计算精度,开发了蒙特卡罗(MC)程序源项子程序,制作了堆内特殊材料截面参数,建立了CAP1400计算模型,采用三维蒙特卡罗程序模拟计算特殊材料在CAP1400堆内的辐射发热率。MC程序能够更加精确地计算出CAP1400堆内特殊材料的辐射发热率,而且能够给出辐射发热率的空间分布,从而更好地支持堆内特殊材料相关的灰棒等部件的国产自主化设计。29016019 相似文献
