The result verifies that the macrocharacter of the slope slide is controlled by the relief of residual tectonics stress and waterfilm of the weak layer. 研究结果表明，该矿软岩边坡的破坏特征受控于残余构造应力释放及泥化夹层水膜化效应。
Landfills without the benefit of a naturally impermeable layer use plastic liners and imported clay. 没有受益于天然不透水层的垃圾填埋场使用塑料衬管和进口粘土。
A mathematical model for groundwater pollution in a leaky aquifer system,which involves the adsorption of semipervious layer,is presented. 提出了一个越流含水层系统考虑弱透水层吸附作用的地下水污染数学模型。
