| 摘 要： | 收集了163个Blazar天体在低态时不同波段流量、红移、黑洞质量的数据(其中有86个BLLacs天体和77个FSRQs天体),通过研究和分析不同波段流量与红移,以及不同波段流量间的相关性,统计得到FSRQs的红移比BL Lacs的红移偏大,FSRQs的平均黑洞质量大于BL Lacs的平均黑洞质量,预示BL Lacs与FSRQs的γ辐射机制可能不同,并且表明Blazar的两个子类BL Lacs与FSRQs的物理性质可能存在差异。

| Abstract: | The data of radiation fluxs at different bands,redshift,black hole mass of 163 BLazars（including 86 BL Lacs objects and）FSRQS objects in low state is collected and the correlations between different band fluxs and between band fluxs and redshift are analyzed It is indicated that the redshift of BL Lacs is smaller than that of FSRQs and the black hole mass of FSRQs is greater than that of BL Lacs.Besides,the γ radiation mechanism for BL Lacs and FSRQs may be different.The results support that the systematic difference between BL Lacs and FSRQs. |
