摘要
分析了现行光栅实验中将平行光斜入射作为正入射条件处理引起的误差。验证了当入射角α<2·5°时,在实验精度范围用正入射公式处理是可行的,但当入射角较大时则须用斜入射公式处理。
In current grating experiment, it is usually regarded glancing incidence as normal incidence that caused processing date error. The discussion showed that processing data with the normal incidence formula is suitable if the incidence angle α 〈 2.5°, otherwise it should deal date with glancing incidence formula.
