摘　　要：A jet model for the jet power arising from a steady, optically thin, advection dominated accretion flow （ADAF） around a Kerr black hole （BH） is proposed. We investigate the typical numerical solutions of ADAF, and calculate the jet power from an ADAF using a general relativistic version of electronic circuit theory. It is shown that the jet power concentrates in the inner region of the accretion flow, and the higher the degree to which the flow advection-dominated is, the lower the jet power from the ADAF is.A jet model for the jet power arising from a steady, optically thin, advection dominated accretion flow （ADAF） around a Kerr black hole （BH） is proposed.
