| 1. | 0 . 002mm extraction of forest soil clay 森林土壤粘粒 |
| 2. | Based on the experimental data , a muddy water infiltration law formula was built 浑水中物理性粘粒含量越大,累积入渗量就越小。 |
| 3. | Middle reaches canal head foundation is the non - cohesive soil , extremely loose silt sand 中游渠道地基是粘粒极少、极松散的粉细沙层。 |
| 4. | And the more the soil clay index is , the less the accumulation infiltration amount is 结果表明,浑水与清水入渗的差异主要是由浑水中物理性粘粒的存在引起的。 |
| 5. | Clay fraction is dominated by illite and kaolinite with small proportions of smectite , chlorite and vermiculite 粘粒组成主要为伊利石和高岭石,也有少量蒙皂石、绿泥石和蛭石。 |
| 6. | Clay minerals and surface chemical characteristics of soils developed under a palaeosol in lower west mountain area of beijing 北京西山古土壤母质上发育的土壤之粘粒矿物与表面化学特性 |
| 7. | With soil becoming dried , more available k was fixed . k had closely relationship with o . m . , cec , clay content , and physical clay content K与土壤有机质、 cec 、粘粒含量、物理性粘粒含量,以及基础土样的有效钾含量基本上呈显著相关关系。 |
| 8. | Equation of f = a + blnw was very fitful to describe the relationship of f and w ( % ) . 7 . dci had significant positive correlations with cec , clay content , and physical clay content 钾离子、氯离子的扩散系数分别与土壤阳离于交换量( cec ) 、物理性粘粒和粘粒含量呈显著负相关或正相关关系。 |
| 9. | The black earth is a kind of alfisol , with a thick layer of humus , loose texture , high fertility , high porosity ratio , poor permeability and a high content of clay , which is suitable for cultivation 摘要黑土是一种腐殖质层厚,质地松散,肥力很高,孔隙比较大而透水性差,粘粒含量高,适于耕作的淋溶土。 |
| 10. | The bulk density was 1 . 2 g cm - 1 . the soil contents about 60 % of silts and about 15 % of clays . a slope adjustable flume of 3 by 8 m was subdivided into 15 mini - flumes of 0 . 2 by 8 m 土壤颗粒以粉沙为主,粉沙粒占总量的60左右,粘粒约占15左右,容重约为1 . 2gcm ~ ( - 1 ) ,试验前将土样风干并过1 1cm的粗筛。 |
