查询词典 snell

When parallel laser beam is irradiating the bubble in the prism, circular interference fringe is produced in the far-field. Based on the far-field theoretical model, the angle position of interference fringes outside the prism is measured with spectrometer and converted into the angle position of interference fringes inside the prism according to Snell's law and then bubble diameter is calculated with computing software Mathematica, the relative difference of which is 0.2%.

平行激光束照射到棱镜中的气泡时，在远场将产生圆环状干涉条纹，利用气泡远场干涉理论模型，使用分光仪对三棱镜外干涉条纹角位置进行测量，由折射定律换算为棱镜内干涉条纹角位置，进而使用计算软件mathematica计算出气泡直径，其相对差为0.2%。
