It is called the optical wedge, when the refractionAngle of the refracting prisms is tiny.
当折射棱镜折射角很小时，称之为光楔。

Based on the analysis of present methods for atmospheric refraction correction, a new correction model is put forward based on the refractionAngle of the line of sight.
本文在分析现有水准折光改正方法的基础上，导出了一种基于水准视线折光角的改正模型。

The stability of the reconstruction procedure is discussed using the condition number of matrix, and the theoretical maxima of the refractionangle and USAXS distribution width are given.
