Air sparging is widely used for remediating groundwater contamination of solvents or gasoline fuels. Air is injected into the saturated zone in the plume area through sparging well. Injected air contacts the contaminated groundwater and removes volatile organic compounds by volatization.

气提法应用在地下水及土壤污染整治的原理是将空气由注气井打入受污染区域的饱和含水层，注入地下水层的空气与非水相的挥发性有机污染物接触，会将污染地下水层的挥发性有机物挥发出来，并往上流入非饱和层中，再由抽气井抽出非饱和层之气体，将污染的挥发性有机物回收到地表进行处理。

Under large-scale environment and so on building underlying bed, underground market, underground parking garage, the mobile communication signal is weak, the handset was unable normally to use, has formed the mobile communication blind spot and the shadow region; In among floor periphery, because comes from different base depot signal overlapping, has the pingpong effect, the handset frequent cut, even falls the speech, seriously has affected the handset normal use; In building high level, as a result of the base depot antenna high limit, is unable normally to cover, also is the mobile communication blind spot.

在大型建筑物的低层、地下商场、地下停车场等环境下，移动通信信号弱，手机无法正常使用，形成了移动通信的盲区和阴影区；在中间楼层，由于来自周围不同基站信号的重叠，产生乒乓效应，手机频繁切换，甚至掉话，严重影响了手机的正常使用；在建筑物的高层，由于受基站天线的高度限制，无法正常覆盖，也是移动通信的盲区。

According to the 137Cs concentration distribution along a typical profile A-1, the sediment accumulation rate and the natural surface soil erosion rate are respectively 16.6t/km^2a and 45.95t/km^2a, which shows that about 63.88% of the eroded surface soil is removed by way of underground loss. The relative contribution ratio of surface soil loss and underground soil loss are respectively 70.13% and 29.87%. By comparison to the utmost soil formation rate 13.51t/km^2a in Maolan, the risk of soil erosion in the Engineering Monument grass-covered depression is higher.

2根据草地洼地典型堆积农耕地土壤剖面A-1的137Cs浓度分布特征，1963年以来的流域平均堆积泥沙数量是16.6t/km^2a，流域平均土壤侵蚀速率为45.95t/km^2a，约占侵蚀产沙数量63.88%的泥沙以地下流失的形式散失；(3)草地洼地小流域内地面土壤流失与地下土壤流失的相对贡献率分别是70.13%和29.87%；(4)以茂兰地区最大成土速率为依据推算出的允许土壤侵蚀量是13.51t/km^2a，草地洼地的土壤侵蚀危险程度极高。

The local factors such as topography, vegetations and soil moisture contents, have great influences on the distribution, ground temperatures, and ground ice contents of permafrost. About 50 km of wetlands have been identified along the China-Russia crude oil pipeline route. In these segments, the surficial deposits consist of peat and humic layers on the top of thick ground-ice, or ice-rich permafrost. The frozen ground engineering geology conditions in wetlands generally are the worst for building and operating the pipeline. The hazardous periglacial processes, such as the widespreadpresence of pingos, icings and frost mounds due to the extensive occurrence of the frost-susceptible soils and ample supplies of surface and ground waters in winter pose significant threats on pipeline operation.

地形地貌单元、植被分布、地表水分条件的变化等局部因素对多年冻土的分布和地下冰的赋存产生重要的影响，管道沿线大约分布有50 km左右的沼泽湿地，其表层为腐殖质土及泥炭层，泥炭层下面分布着含土冰层或地下冰，是管道沿线最差的冻土工程地质地段；由于中俄原油管道沿线水系发育多，冻胀丘、冰椎和冰幔等不良冻土现象广泛分布。
