收集了91个BL Lac天体样本的X射线资料,其中62个高峰频BL天体-HBLs,29个低峰频BL天体-LBLs.计算了它们的X波段光度,研究了它们的X射线谱指数αX与光度L X的关系.结果表明： HBLs的谱指数αX与光度值L X无相关,而LBLs的谱指数αX与光度值L X有较弱相关性.
收集瞭91箇BL Lac天體樣本的X射線資料,其中62箇高峰頻BL天體-HBLs,29箇低峰頻BL天體-LBLs.計算瞭它們的X波段光度,研究瞭它們的X射線譜指數αX與光度L X的關繫.結果錶明： HBLs的譜指數αX與光度值L X無相關,而LBLs的譜指數αX與光度值L X有較弱相關性.
수집료91개BL Lac천체양본적X사선자료,기중62개고봉빈BL천체-HBLs,29개저봉빈BL천체-LBLs.계산료타문적X파단광도,연구료타문적X사선보지수αX여광도L X적관계.결과표명： HBLs적보지수αX여광도치L X무상관,이LBLs적보지수αX여광도치L X유교약상관성.
An X-ray data sample of 91 BL Lac objects is collected, in which, there are 62 HBLs (High-peak frequency BL Lacs) and 29 LBLs (Low-peak frequency BL Lacs). Based on the sample, the X-ray luminosities are calculated and the correlation between the αX (X-ray spectral indices) and LX (X-ray luminosities) is studied. The results show thatαX are not correlative with LX for HBLs, whileαX are marginally correlative with LX for LBLs.
