2.the rays of light are refracted by the material of the lens.
光线经片材料而射。
3.According to geometric feature of spherical surface,the misalignment characteristics of single spherical refracting system when the refracting surface was tilted and decentered were analyzed.
根据球面的几何特征,分析了单球面射光学系统射面倾斜和偏心时的失调特征;
4.During this alignment, each crystal can act like a miniature lens, refracting sunlight into our view and creating phenomena like parhelia, the technical term for sundogs.
