5.The phenomena can be observed in the tests low seepage pressures can easily form passageways behind the waterproof layer if there is no drainage layer or the drainage layer is blocked in the single-shell test slab; the waterproof layer can resist higher seepage pressure if there is no drainage layer or the drainage layer is blocked in the double-shell test slab; the seepage water can be controlled and drained away in the drainage layer by the water proof layer only if there is unblocked drainage layer behind it in the double-shell test slab.
由试验可见，在单层试验板中没有排水层或排水层不通畅时，较低的水压就能在防水膜后形成渗流通路；在双层试验板中没有排水层或排水层不通畅时，防水膜能抵抗一定程度的渗漏水压；只有在双层试验板中的排水层畅通时，防水膜才能有效地将渗漏水控制在排水层中排走。
6.In making use of the drainage as resources, there are several advantages:1) there already exist a certain number of drainage networks which are not very difficult to extend and remold:2) deserts can be used as object for drainage utilization;3) the drainage is still barely suitable for irrigation of salt-tolerant plants.
在塔里木河干流，农田排水资源化利用有如下几个有利条件：(1)农田排水有一定数量且渠网的延伸和改造难度不大；(2)荒漠可作为农田排水资源化利用的场所；(3)农田排水仍可勉强适于耐盐植物生长。
7.The geology characteristics of the coal field and the distribution characteristics of the CBM (coal-bed methane) resourse in China were analyzed briefly, and the technologies of methane drainage and CBM utilization and its suitablity were researched, and the problems of methane treatment and CBM development were analyzed, and the technical measures for promoting and strengthening the methane treatment such as strengthening the gas drainage, excavating after gas drainage, choosing the method of gas drainage according to its condition were put forward.
