soil pores meaning in English
土孔隙
土壤孔隙
Examples
- Gums and mucilages can reduce the size of some of the soil pores .
细菌胶和粘胶会使某些土壤的孔隙减小。 - 5 . to describe soil water movement with fractal model . the effect of soil pore radius and pore connectivity on soil water movement was studied . in addition of pore connectivity , the prediction of unsaturated hydraulic conductivity is more improved in low water content
将新的土壤结构分形维数应用于对土壤水分运动参数的描述,使饱和导水率和非饱和导水率预测的准确性有了很大程度地提高。 - In low matric potential state , the a & p model can be use to predict water retention characteristics , but in high matric potential state , it cannot get good result . in addition of soil pore connectivity , to correct the a & p model , it can get good result in whole water content range
但在高吸力段a & p模型预测的结果与实际偏差较大,考虑到土壤孔隙实际联通状况,修正a & p模型,使供试的四种在整个含水量范围对土壤水分特征曲线都得到了较好的拟合。 - The phase change of soil moisture and inflation of the frozen moisture c ause the reduction of hydraulic conductivity by reducing the area of flow section and the aperture of soil pore space , increasing the capillary resisting force to soil moisture , and decreasing the water potential gradient because of the increasing of movement distances of soil water
导水率减小是冻结土壤入渗能力减小的根本原因,而土壤中液态水的相变是导水率减小的根源所在。土壤水分的相变及其膨胀通过减小土壤水分过水断面面积和孔隙孔径,增大阻力和由于增长运动距离而减小水势梯度使冻结土壤的导水率降低。 - 4 . the soil structure fractal dimension ( ds ) is defined to describe to soil pore connectivity . when the ds is smaller than the dp , soil pore connectivity is change better , when the a is bigger than the dp , soil pore connectivity is change worse . the ds and difference between the ds and the dp is sensitive to the variety of soil structure , they can be use to describe the variety of soil structure
土壤结构分形维数d _ s与其粒径分布分形维数d _ p的差值对不同质地的土壤水分特征曲线的变化是十分敏感的, d _ s和为土壤结构的定量化描述提供了两个全新的指标, d _ s反映了不同质地土壤的结构状况,反映同种质地土壤的结构变化。
