摘要：
We present non-LTE calculations of the structure of optically and geometrically thin accretion discs. For realistic parameters equilibrium usually occurs at a nearly constant temperature 6000-8000 K. Non-LTE calculations are indispensable for both the structure and emission spectra of the optically thin part of the discs: LTE calculations give incorrect results.
