摘　　要：为研究夫琅禾费单缝衍射中单缝的缝宽,首先根据夫琅禾费单缝衍射暗纹产生的条件,推导出计算单缝缝宽的理论公式,根据公式,主要计算了实验中衍射中心条纹到各级暗纹间的距离。然后对测量单缝衍射光强分布的实验方法进行了详细阐述。最后根据实验数据,通过传统计算法和规划求解法分别求解出单缝缝宽。对比两种方法,利用规划求解法求解缝宽,准确度可以进一步提高。通过以上研究,不仅提高了缝宽的计算精度,而且对单缝缝宽的测量具有一定的指导意义。This study focuses on investigating the slit width of a single slit in Fraunhofer single slit diffraction.Initially,a theoretical formula is derived to calculate the slit width based on the conditions for generating dark stripes in Fraunhofer diffraction.Subsequently,the experimental method for measuring the intensity distribution of single slit diffraction is outlined.Finally,the slit width is calculated using both traditional and programming methods,with the programming method demonstrating enhanced accuracy.This research not only improves the calculation precision of the slit width but also provides valuable guidance for measuring the slit width of a single slit.
