树木根系吸水引起土壤含水率显著降低,从而导致胀缩性地基沉陷。
3.
Based on the observed data of the alternately partial root zone drip irrigation and the root distribution of grape,a two-dimensional root water uptake model and function of soil evaporation related to soil water content were proposed.
在根系分区交替滴灌土壤水分动态和根系分布试验观测的基础上,提出了葡萄二维根系吸水模型,并确定了与土壤表层含水率有关的棵间土壤蒸发方程,然后在土壤水分运动基本方程的基础上结合交替滴灌的入渗特性,建立了根系分区交替滴灌的土壤水分动态模型(APRI-Model),模型考虑了该种灌水方式下棵间土壤蒸发和根系吸水的变化特征。

补充资料：人工牙根
分子式：
CAS号：
性质：如果患者仅是单个牙齿受损或因患疾而非拔去不可，但齿床仍完好，那么可以把人工材料的牙根种植在人的齿槽骨上使之与组成相适应，这种齿根就称为人工牙根。聚甲基丙烯酸甲酯和聚砜都可用来制作人工齿根，它们与牙床肉黏附性良好，没有感染，也能在齿槽骨内牢固形成相关连的组织。
