【摘要】 使用一种测定超滤膜的微孔大小、孔径分布和平均孔径的新颖实验研究方法—小角Ｘ射线散射（ＳＡＸＳ）法，并开发了一个ＳＡＸＳ数据的处理软件，成功地取代了手描切线法．提高了测定结果的准确度和精确度，缩短了数据处理时间更多还原

【Abstract】 A novel experimental research method,small-angle X-ray scattering (SAXS),was used to determine the micropore size,size distribution and mean size in ultrafiltration membrane. A data-processing program was developed,which successfully replaced hand-drawn tangent-line method and increased the accuracy and precision of the results.更多还原
