摘要
本文给出了激光准直系统垂直折光改正的数学模型。在温度梯度的精确值难以获得时,利用精密水准成果计算折光系数是行之有效的办法,文中还以BEPC工程为例,讨论了模型的具体应用。
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.
