For a diffraction grating, the relationship between the grating spacing (i.e., the distance between adjacent grating grooves or slits), the angle of the wave (light) incidence to the grating, and the diffracted wave from the grating, is known as the grating equation. Like many other optical formulas, the grating equation can be derived by using the Huygens–Fresnel principle, stating that each point on … WebApr 1, 2024 · vector为可变长数组(动态数组),定义的vector数组可以随时添加数值和删除元素. 在局部函数中开vector数组,是在堆空间里面开的,与开全局变量比较类似,所以经常见到在局部函数中开大容量数组. 头文件 # include < vector > 初始化. 一维初始化 east point college park delta sigma theta
