摘要:
利用BOSS第二次释放的数据，我们对SDSS J101108+553407的光谱进行系统研究，在观测坐标系5200 Å~8700 Å范围内，可以证认出吸收线红移为3.2983，3.3431，3.3542，3.3583的4个窄吸收系统，我们发现Nvλλ1238、1242双线吸收系统有明显的光变现象，其等值宽度平均增强约166%。
Based on the second released data of Boss, we begin with a system research on the SDSS J101108 + 553407 spectrum. Within the observable scope of the coordinate system 5200 Å~8700 Å, we may recognize four narrow absorption systems with the red shifts of absorption lines 3.2983, 3.3431, 3.3542 and 3.3583 and find an obvious light variation phenomenon on the double line absorption system of Nvλλ1238, 1242, and its equivalent width enhances 166% averagely.
