陶粒濾料是以精製陶土為主要原料，摻加適量改性劑，經粉碎，混練，成型和高溫煅燒而製成的，不含任何對人體和環境有害的物質.其表面堅硬，粗糙，內部疏鬆，多孔，具有機械強度高，比表面積大，孔隙率大的特性.用於水處理中，具有表面性狀好，截污能力強，過濾水頭損失小，反沖洗耗水量低，化學穩定性和生物學穩定性好，使用壽命長的特點.陶粒濾料是一種能增加水產量，提高出水質量，節省藥劑和能耗的新型高效過濾材料The change of big pore section shape has more influence on soil water movement, but in small pore channels, the influence is small, in addition of pore section shape, it can get better prediction of unsaturated hydraulic conductivity
粗大孔隙通道的截面形狀及變化對水分運動影響較大，較細空隙通道截面的形狀對水分運動影響較小。修正孔隙截面形狀對水分運動的影響，進一步考慮孔隙截面形狀因子對土壤水分運動的影響，可以得到對土壤水分運動參數更正確地預測。Grain contact models suggest that dry k / ratio remains a constant with varying porosity, differential pressure and mineral properties and vary with roughness of grain contact
顆粒含量模型說明，乾燥k /比不受孔隙度、差壓和礦物特性的的影響，但是要隨顆粒含量的粗糙度變化。Suggest the method of division to measure the largest compacted dry density of dam ' s material with super large diameter approximately. according to the research of predecessor, suggest applying the effective void ratio or the effective void rate to compute the coefficient of permeability approximately
採用了表面振動法進行室內最大幹密度的研究，提出了比例法近似測定超徑粗粒土最大幹密度；在前人研究的基礎上，提出採用有效孔隙率或有效孔隙比的滲透系數近似估算。Natural stone test methods - determination of real density and apparant density and of total and open porosity ; german version en 1936 : 1999
