摘要：High-resolution observations of the black hole candidate GRS 1915+105 have shown the radio emission to be dominated by a compact steady jet (< 20 mas), whilst in the low/hard state (e.g. Dhawan et al. 2000). We have found a close relationship between the X-ray and radio emission from the steady jet using the Ryle Telescope and RXTE-ASM. This was fitted by an empirical relationship of SX−ray µ Sx radio, with a power-law index of x 1.7. This suggests either a turn-over of the Gallo et al. (2003) universal XRB relationship, from a radiatively efficient to inefficient accretion disk or direct evidence of a variation in another fundamental parameter, e.g. accretion radius
