1. In addition, pressure change of volatile oil well with time and distance during degassing percolation is presented. 描述了挥发性油井在脱气渗流过程中压力随时间和距离的变化规律；
2. Experimental results show that; with the increase of cements, the cohesive force and friction angle increase; the percolation coefficient decreases. 试验结果表明，随着水泥掺入量的增加，粉细砂的凝聚力和内摩擦角增大，渗透系数减小。
3. The pollution situation of garbage disposal plant and the harm to Qiandao Lake are analysed by monitoring percolation fluid and the near water regions. 通过对垃圾场渗滤液和附近水域监测，分析了垃圾场的污染状况和对千岛湖造成的危害。
