refraction angle

基本解释

It is called the optical wedge, when the refraction angle of the refracting prisms is tiny.
当折射棱镜折射角很小时，称之为光楔。
How is this possible, four thousand years ago, the Egyptians have been able to so accurately grasp the refraction angle calculated?
这怎么可能，四千年前的埃及人就已经能够这么精确地掌握折射角度的计算了吗？

The stability of the reconstruction procedure is discussed using the condition number of matrix, and the theoretical maxima of the refraction angle and USAXS distribution width are given.
利用矩阵条件数对方程求解的稳定性进行了讨论，推导出理论上的折射角和小角散射宽度的最大值。
