【摘要】 为了提高实验的精度以及实验的可操作性,对后向散射法测量湿蒸汽的实验方案进行了优化研究。本文研究了入射光射入位置、入射光光强、散射光接收角度三个因素对实验结果的影响。实验结果表明,这三个因素对散射光光强以及其对应的灰度值具有较大的影响;当入射光光强为20mw、入射位置为第四截面、散射光接收角度为后向30°时,可获取到最佳的散射光图像,此时为最优的实验方案。该实验方案的研究对后向散射法测量湿蒸汽具有重要的指导作用。更多还原

【Abstract】 In order to enhance the accuracy and operability of backscattering method in wet steam measurement and,three effecting factors,namely the incident light position,intensity of incident light,receiving angle,was compared in this paper; the results show that these three factors have a great influence on the intensity of scattering light and gray value; the scheme that 20 MW of the incident light from the fourth section into the cylinder and receives scattering light at 30°can get the best image of scattering light. The scheme is helpful for backscattering method in wet steam measurement.更多还原
