| 摘 要： | 采用图像分析法测定大孔交联聚苯乙烯树脂的 现大孔交联聚苯乙烯的外表面具有分形结构，分形维数在２和３之间，将图像分析法测定的分形维数与小角Ｘ－射线散射法测得的结果对照。发现两种方法测定结果虽然不同，但在不同树脂之间的变化趋势是一致的，因此，可用图像分析法比较不同大孔树脂分形结构的差别。 |

| Abstract: | The structure of macroporous crosslinked polystyrenes was investigated by microscope and image analysis. It was found that fractal structure existed in out-surface of these polymers, and the fractal dimension DMIA was ranged from 2 to 3. The fractal dimensions DMIA, which were obtained by microscope and image analysis, were compared with the fractal dimensions DSAXS, which were obtained by small angle X-ray scattering. The results showed that the varying tendencies of DMIA and DSAXS were the same though the values of DMIA and DSAXS were not the same. Thus, microscope and image analysis may be used as an audio-visual method to compare the fractal structure of various macroporous resins. |
