1.Soils start to dry from the surface but subsoils may remain wet so that rice roots can absorb available water.
土壤由表面开始干燥，但底土潮湿，因此，水稻能吸到有效水。
2.Finally, the authors point out some important problems for seismic behaviour analysis of shallow foundation on natural subsoils.
最后，指出了天然地基浅基础抗震研究应着重注意的几个问题。
3.Grape vines thrive in well-drained soils with loamy to sandy surface layers over moderately permeable clay subsoils.
葡萄可以在表层土壤从肥沃到沙质，具有适度渗透力的粘土底层土中有非常好的生长。
4.Furthermore, their small size makes it easy for them to penetrate hard-to-reach environments such as subsoils and groundwater.
此外，由于微生物很小，也更易于被送到底土、地下水等不易到达的环境中。
5.Stable response of two-dimensional Biot consolidation of saturated multilayer subsoils under cyclic loading
