| Abstract: | In this paper a mathematical model for the vertical refraction correction of lasercollimation system is derived. The refraction coefficients involved in the model can becalculated by precise levelling results, which is very useful when precise observationsof temperature gradient are not available. The application of this method to BeijingElectron Positron Collider(BEPC)project is discussed. |
