摘要
介绍用TurboC编程序，在《微波布拉格衍射》实验中，绘制衍射强度I与入射角α的关系曲线，按理论值，第一级衍射极大值在α66°附近，第二级衍射极大值在α37°附近．程序中能自动标示出这二个极大值的数值及其所在的角度．
The programs of drawing relation curve of diffraction intensity and angle of reflection are introduced in Turbo C. In the experiment of Bragg 's diffraction of microwave, according to theoretic value the maximum of first order of diffraction appears near α 66°,and the maximum of second order of diffraction appears near α 37°. Two maximums and the correspounding angles of reflection are demonstrated automatically in the program.
