| 摘 要： | 用JWG型微机塞曼效应实验仪研究分析谱线分裂,调节出最佳的光学系统,得到高对比度、清晰可辨的干涉条纹的分裂谱图.利用计算机图像数据处理系统分析所拍摄的高对比度、清晰的π线谱图,测得电子的荷质比为1.759×1011 C/kg,与公认值1.76×1011 C/kg的相对误差为0.029%,与精确测量值1.75881962×1011 C/kg的相对误差为0.38‰.结果表明,高对比度、清晰可辨的分裂谱图不仅直观、准确演示塞曼效应,也极大提高实验结果的精确度.

| Abstract: | Investigating splitting of spectrum of Zeeman-effect by the JWG-based computer experimental apparatus,and the high-contrast and clear split spectrum could be obtained after optimally adjusting optical system.Using of data processing system of computer to analyze the captured and high-resolution π spectral lines,and measure electron charge-mass ratio of 1.759×1011 C/kg.Compared with well-accepted value of 1.76×1011 C/kg,the relative error is 0.029%;and Compared and precision measurement value of 1.75881962×1011 C/kg,relative error is 0.38‰.The results show that a high-contrast and clear split spectrum not only can directly and accurately demonstrate Zeeman-effect but also greatly improve the accuracy of experimental results. |
