程序1实现了一维Airybeam的三维图形，从x-y面可以看出Airybeam的传输轨迹，三维图形的z轴是光强； 程序2实现了1维Airybeam的轨迹控制，通过改变wm和wg的值可使光强的最大值在任意位置。(A three-dimensional graphics program to achieve a one-dimensional Airybeam the xy plane can be seen Airybeam transfer trajectory, and three-dimensional graphics z-axis is the light intensity 2 implements the program track 1-dimensional Airybeam control, by changing the value of wg wm and the light intensity at an arbitrary position allows the maximum.)
