| 中文摘要: |
| 利用Image-pro plus图像处理软件，分析研究了絮凝体SEM 图像，提取了絮凝体外形尺寸及絮凝体内孔隙直径、孔隙率、孔隙比等特征，分析了这些特征与泥沙浓度及絮凝剂浓度的关系。结果表明:采用Image-pro plus软件处理得到的絮凝体结构特征的变化规律与现有结论基本一致，絮凝体沉速随着絮凝体孔隙比的增大而减小，证明了Image-pro plus软件应用于分析絮凝体SEM图像的可行性。 |
| 英文摘要: |
| Using Image-Pro plus software, we analyzed the SEM images and extracted the features of flocculation, such as the diameter, pore diameter, porosity, and void ratio. We also analyzed the relationships between the features mentioned above and sand concentration, and between these features and flocculant concentration. The results of flocculation characteristics variation laws using the Image-pro plus software were consistent with the existing conclusions, and flocculation setting velocity decreased with the increasing void ratio. Therefore, the Image-pro plus software can be applied to analyze the SEM images of flocculation. |
