Leaching experiments of metakaolin show that the final al extraction rate in a batch reaction is strikingly influnced by the inferior pore struture geometry of the metakaolin pellets 在轻度润湿状态下制备的高岭石团粒，经煅烧后，仍具有发达的粒内大孔结构。

Because these factors make change more often , soil time space variability is more bigger . the relationship of single factor between soil water infiltration capacities and certain influencing factor could be established quantitatively by means of soil water infiltration tests in indoor , there is negative correlation relation between soil water infiltration capacities and soil structure . there is negative correlation relation in high grit content and low physical clay content soil , and second - degree polynomial relation in high physical clay content junk structural soil between soil water infiltration capacities and soil moisture 由于这些因素在时刻发生变化，使得土壤的时空变异性较大，只能用室内土壤水分入渗试验来定量确定土壤水分入渗能力与某些影响因素之间的单因子相关关系，土壤水分入渗能力与土壤结构之间呈负相关关系，土壤水分入渗能力与土壤含水量之间在土壤砂粒含量高，物理性粘粒含量低的无结构土壤中呈负相关关系，在物理性粘粒含量高的团粒结构土壤中呈二次多项式关系。

The results are summarized below : 1 ) study on soil science indicates that soil granular structure is the focus adjuster for soil fertility and it affects the space , water - grasp , aeration and anti - erosion of soil . and the percentage of aggregate is one of the key index that decides the speed and extent of soil erosion , hardening and degeneration because the soil degeneration will first lead to the disappearance of crumb - structure . so it is very important that the physical course and character of soil in different land use pattern are realized 现将主要结果摘要如下： l 、士壤学研究表明，团粒结构是土壤肥力的中心调节器，影响着土壤的空隙性、持水性、通透性和抗蚀性；任何土壤的退化首先将表现出团粒结构的消失；团聚体百分比是决定土壤侵蚀、板结等物理过程速度和幅度的关键指标之一，了解不同土地利用和土壤管理方式的物理过程和性质相当重要。
