【 摘 要 】

In this work, we explore a sample of 362 flat-spectrum radio quasars (FSRQs) to investigate the jet formation. We find that the fundamental plane for our FSRQs can be expressed as 𝐿5;GHz ∝ 𝑀$^{-0.19}_{ext{bh}}$ 𝐿$^{1.08}_{ext{2; keV}}$. We also find that the 5 GHz luminosities are tightly related to both black hole mass and Eddington ratio, which is established as 𝐿5;GHz ∝ 𝑀$^{0.67}_{ext{bh}}$ (𝐿bol/𝐿EDD)1.32.
