摘要：

Contact binaries can be used for distance determinations of stellar systems. They are easy to discover and identify and are very abundant among solar-type stars, particularly for M-v > +3. The period-luminosity-colour (PLC) relations have similar properties to those for pulsating stars and can currently predict individual values of Mv to about +/-0.25 mag. (C) 2004 Elsevier B.V.
