1) sand sizes
沙粒粒径
1.
On the bases of simulation experiments in laboratory,the effects of sand fragments and sand sizes on saturated hydraulic conductivity(Ks10) of sodic soil,electrical conductivity(EC) and pH of leachates were investigated,and relationships between Ks10 and EC of leachates,Ks10 and pH of leachates were established.
结果表明:随沙粒添加量逐渐增加,碱土饱和导水率不断升高,两者呈极显著指数关系;碱土饱和导水率随沙粒粒径增加呈无规律的变化趋势;出流液电导率和pH值随沙粒添加量增加而降低,电导率和沙粒添加量间存在指数函数关系,但pH与沙粒添加量间无函数关系;出流液电导率和pH值随沙粒粒径增加均呈无规律变化趋势;出流液电导率和pH值均随饱和导水率的升高而降低,二者与饱和导水率间均呈对数关系。
