毛管孔隙 meaning in Chinese
capillary interstice
capillary pore
Examples
- It was showed that forest with good structure could improve the soil noncapillary porosity and water conversation function , and it was implied that forest with rational structure stored rainfall and surface runoff quickly
表明具有良好结构的林分，可有效改善土壤非毛管孔隙度和滞留贮水功能，从而有效地提高对降雨的快速贮存以及蓄洪与涵养水源作用。 - Compared to stipa bungeana grassland and fallow ground , the volume weight was smaller , total porosity and capillary porosity were higher , but non - capillary porosity was lower . 2 . achnatherum splendens height increased slow in the initial stages , fast from june to august and slow again after that
芨芨草草地土壤容重较本氏针茅草地和裸地小，各层的总孔隙度和毛管孔隙度明显高于本氏针茅草地和裸地，但非毛管孔隙度较本氏针茅草地和裸地低。 - ( 6 ) in agroforestry and contour hedgerow treatments , soil structure and soil texture is improved with soil bulk density decreasing and soil porosity and capillary pore increasing . finally , water - holding capacity is improved . ( 7 ) soil loss in small plots of comprehensive management treatments is significantly lower than that in control
… ）实施农林复合经营和生物篱埂技术可明显的改善土壤结构，降低土壤容重，增加上壤总孔隙度和毛管孔隙度，从而提高土壤的保水持水性能。 - When soil antecedent condition is dry and the initial rainfall intensity is high , peak surface runoff also considerably lag behind that of rainfall , because of the formation of temporary relative impermeable top layer ; b ) surface runoff is controlled primarily by infiltration - excess runoff mechanism under unsaturated condition ; the major fraction of surface runoff are dominated by saturated infiltration - excess runoff response , only a small fraction by return flow mechanism when soil is saturated ; c ) subsurface flow is dominated by saturated runoff mechanism , and the duration of subsurface post the rainfall end is dependent upon rather the soil properties than the rainfall characteristics ; d ) subsurface flow intensity in cultivated soil layer ( 0 ~ 20cm ) is high up to 35mm / h when rainfall intensity is up to 120mm / h , indicating the existing of macropores and pipe flow in cultivated layer
2 )耕作制下紫色土的产流主要机制是： 1 )当雨前土壤含水量未达到饱和状态时，表面产流起始时间有明显滞后现象，这与紫色土的快吸水性和较多非毛管孔隙密切相关；当雨前土壤较干燥，降雨初期雨强较大时，易形成临时相对不透水表层，表面产流峰也有明显滞后现象。 2 )表面径流的产流方式主要是超渗产流，当土壤达到饱和状态后，有四川大学博士学位论文小部分回归流发生，但主要是饱和超渗产流发生，因为紫色土的相对不透水层和其它透水障碍层不明显。 3 ）壤中流主要是饱和产流，与降雨过程有明显的滞后，而且雨停后的壤中流产流历时与降雨特征无关。 - With increase of artificial forest age , the content of soil organic matter decreased sharply . and soil physical , chemical and biological properties of forest became worsen . from soil physical properties analysis , soil silt , clay , physical clay , aggregate degree and structure coefficient in topsoil increased with increase of artificial forest age and soil sand deceased
在土壤物理性质方面，随着人工云杉林龄的增加，土壤表层粉粒、粘粒、物理性粘粒、团聚度和结构系数降低，砂粒含量增高，土壤饱和持水量、毛管持水量及总孔隙和毛管孔隙在人工云杉演替过程中表现出“ u ”型变化。
