Soil pore features in red soil

The red soil pore structural characteristics at four different moisture levels, ranging from <b>dry </b>(8%), <b>semi-dry</b> (12%), <b>semi-wet</b> (23%) to <b>wet </b>(30%) conditions, were analyzed using nuclear magnetic resonance (NMR) spectroscopy, environmental scanning electron microscopy (ESEM), and X-ray computed tomography (CT) scanning.

本研究采用核磁共振波谱法（nuclear magnetic resonance spectroscopy, NMR）、环境扫描电子显微镜（environmental scanning electron microscopy, ESEM）与X射线计算机断层扫描（X-ray computed tomography, CT）三种表征手段，对**干态**（8%）、**半干态**（12%）、**半湿态**（23%）及**湿态**（30%）四种不同含水率条件下的红壤孔隙结构特征展开了分析。
