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%。

Among them heart scope about the spherical surface inside that diameter is 10 kilometers of.

The simulation results show that staged air can significantly reduce tangential circle diameter of upper parts of furnace and lower heat transfer difference of horizontal gas flue; the field test results show that the proper ratio of staged air in the total air can make tubes wall temperature distribution of high-temperature superheater uniform, and tubes' peak temperature lowered 5~10℃.

模拟计算结果表明炉内分级送风对于减小炉膛上部切圆直径、降低水平烟道内的热偏差作用明显；现场试验结果表明，适度增大炉内分级送风比例使高温过热器管壁温度分布更均衡，峰值温度降低5～10℃，使受热面运行安全性得以提高。
