我们分别研究费米耀变体和非费米耀变体的喷流功率与吸积之间的关系。我们还比较了它们之间的相关参数。我们的主要结果如下。 (i) 费米耀变体和非费米耀变体在红移、黑洞质量和宽线光度方面具有显着差异。 (ii)费米耀变体比非费米耀变体具有更高的平均核心主导参数，这表明费米耀变体具有很强的束流效应。 （iii）我们发现费米和非费米耀变体的粗线发射和喷流功率之间分别存在显着相关性，这表明喷流和吸积之间存在直接的紧密联系。 (iv) 吸积和黑洞质量可能分别对费米和非费米耀变体的射流功率有不同的贡献。
We study the relationship between jet power and accretion for Fermi and non-Fermi blazars, respectively. We also compare the relevant parameter between them. Our main results are as follows. (i) Fermi and non-Fermi blazars have significant difference in redshift, black hole mass, and broad line luminosity. (ii) Fermi blazars have higher average core-dominance parameter than non-Fermi blazars, which suggests that Fermi blazars have strong beaming effect. (iii) We find significant correlation between broad line emission and jet power for Fermi and non-Fermi blazars, respectively, which suggests a direct tight connection between jet and accretion. (iv) The accretion and black hole mass may have a different contribution to jet power for Fermi and non-Fermi blazars, respectively.
