1. In this thesis, we change the triangle blazed grating in Littrow Mounting situation into binary grating, analyze and simulate the binary grating, and compared the both gratings. 本文将自准直入射下的三角形闪耀光栅等价成二元光栅，对等价后的二元光栅的性能进行了分析和模拟，并同自准直入射下的三角形闪耀光栅做了比较。
2. The resolving power of the actual grating system is verified by observing the double line of natrium in the experiment of diffraction grating. 本文通过光栅衍射实验对钠光双线结构的观测，验证了实际光栅系统的分辨本领。
3. A lot of grating messages including its profile can be derived from diffraction spectrum of grating according to Fourier optical theory. 根据传立叶光学理论人光栅的衍射频谱中可以反推光栅本身的多种信息，包括其形貌特徵。
4. The modified formula can be used to simplify the design and simulation for integrated photonic devices such as arrayed waveguide grating (AWG) and etched diffraction grating (EDG). 把这种修正方法应用到平面光集成波导器件，如阵列波导光栅（AWG）、蚀刻衍射光栅（EDG）等器件的设计和模拟中，可以大大降低工作的复杂性，同时可以得到精确的结果。
5. In this paper, regarding the first home—made concave diffraction grating machine as example, the influence of rolling center deviation of crossed elastic support on grating accuracy is discussed. 本文以我国第一台凹面衍射光栅刻划机为例，研究了十字形弹性支承转动中心的变化对光栅刻划精度的影响。
