摘　　要：结合光致聚合物中光化学反应的基本过程及其理论函数模型,对多种采用不同双染料敏化的光致聚合物的透射率曲线进行拟合,得到了光化学反应理论模型中的参数。依托于实验数据,分析了利用MATLAB实现曲线拟合并得到光致聚合物中各光化学参数的新方法。结果表明:当曝光波长为632.8 nm,曝光强度为65 mW/cm2时,3种光致聚合物的拟合统计指标R-Square值分别为0.9687,0.9958和0.9902,说明所使用的理论结合实验数据的拟合分析方法是成功的。The transmittance curves of the photopolymer which sensitized by different dual-dyes were fitted based on the basic photochemical reaction process of the photopolymer and its theoretical function model,and the parameters in the theoretical model of the photochemical reaction were obtained.A new method to realize the curve fitting by MATLAB and obtain the photomechanical parameters in the photopolymer,based on the theoretical model and experimental data,was analyzed.The analysis shows that the R-Square of fitting statistics for three photopolymers are 0.9687,0.9958 and 0.9902 respectively when the exposure wavelength is 633 nm and the exposure intensity is 65 mW/cm^2.It means that the fitting method is successful.
