Experimental data showing the effect of wetting on soil structure transformations: 3D images

X-ray computed tomography was carried out under two different saturation conditions: air-dried and saturated beyond the field capacity. After the first air-dry tomography scanning, the sample was moistened by supplying excess water through the base standing on several filter papers.

本研究针对样品在两种不同饱和条件下开展X射线计算机断层成像（X-ray computed tomography）扫描：即风干状态与超过田间持水量的饱和状态。完成首次风干态断层扫描后，通过放置于多张滤纸上的样品底座向其通入过量水分以完成润湿。
