The relation between the width of central brightfringe together with full width at half maximum of central brightfringe and every waveguide parameter is analyzed.
分析了中央亮条纹的全宽度和半最大值全宽度随波导参数和传输距离的关系。

The intensity distribution on a screen from dark to bright to dark again is called an interference fringe.
屏幕上的强度分布，从暗到亮再到暗，叫做一条干涉条纹。

The authors show that using the half-wave strip method to deduce the bright and dark fringe conditions of Fraunhofer grating diffraction is simpler than the amplitude vector method.
