| 摘要: |
| 为了有效地评价PVA纤维束的均匀性,基于灰度共生矩阵理论,并以PVA纤维束搅拌分散后图像的角二阶矩和熵值为主要特征参数,建立PVA纤维束分散评价方法,给出了PVA纤维束的均匀性评价指标（f1和f2）,分析了在不同种类分散剂、不同搅拌速度、不同搅拌桨的搅拌参数下PVA纤维束分散效果,绘制了PVA纤维束分散后的角二阶矩和熵值曲线图. 结果表明:均匀性评价方法可以评价PVA纤维束分散的均匀性；利用均匀性评价指标分析获得最佳搅拌分散参数,可实现对PVA纤维分散性的快速准确评价. |

| Abstract: |
| In order to study how to evaluate the dispersion of PVA fiber bundles uniformly, a variety of agitation and dispersion parameters were tested, and based on the theory of gray coexistence matrix, the dispersion evaluation method of PVA fiber was established. The dispersion effect of PVA fiber under different mixing factors, different stirring speed and different stirring blades was analyzed and the angular second moment of PVA fiber bundle and the entropy value of the line graph was plotted. The result shows that the dispersion of PVA fiber bundles can be evaluated by the method well, which provides a theoretical basis for the study of the dispersion uniformity of PVA fiber bundles. |
