中文摘要：

土壤污染问题已经成为当今社会的首要问题,为了探究污染物随土壤水在土壤中的运移规律,首先要摸清水分在土壤中的入渗规律。设计了5组实验,考察了水分在非饱和土壤中的入渗过程,记录了不同位置含水率随时间的演化;针对实验数据,通过绘图进行了统计分析,总结了水分在非饱和土壤中的入渗规律。此次实验器材均根据自身实验需求设计,目的是方便对土柱内含水率的测定以及数据记录。

英文摘要：

Soil pollution has become a main problem in our society. To explore the mechanism of pollutants contaminant migration in soil,one should first understand the law of water infiltration in soil. In this paper,five groups of experiments were conducted to investigate the water infiltration process in unsaturated soil and record moisture content evolution over time on different positions. Based on the analysis of experimental data,statistical analysis was carried out through the drawing,the laws of water infiltration in unsaturated soil were gained. The equipment in this experiment were designed according to the requirement of our aim,mainly for the convenience of observation and data record.
