中文摘要：
使用Matlab7．0对树脂吸附实验数据进行了处理，采用一维三次样条插值方法绘制了实验曲线。使用曲线拟合函数polyfit，采用G．E．Boyd液膜扩散方程、Lansmuir吸附等温式和Freundlich吸附等温式等对实验数据进行了线性拟合，拟合结果和使用Origin7．0拟合结果相同，且线性相关系数均接近于1。
英文摘要：
Resin adsorption experiment data were processed by Matlab 7.0, and cubic spline interpolation was used to draw experiment figures. The polyfit function was used to realize linear fitting d G. E. Boyd＇s diffusion equation of liquid film, Langmuir isotherm and Freundlich isotherm, etc. The results were the same as that made by Origin 7. 0, and the correlation coefficients were all dose to 1.
