As the same section is concerned, near the bottom the maximum value of frequency appear within 1mm of bubble size, towards the water face this value tend to decrease, yet the corresponding size turns to increase; in the same time, the frequency is concentrated near the bottom and deconcentrated near the water face; under the experiment condition, the maximum frequency of the total section approximately appear at 0.5mm size; mean bubble size access 0 at bottom and increase acceleratively towards water face where tend to be infinite; total number increase during developing of aeration, and become steady when reach wholly developed area; on the same section, the total number in unit time tend to increase at first and decrease then, along the water depth.

对于同一断面,靠近槽底的测点气泡个数分布最大值出现在气泡尺寸小于1mm的范围内,朝水面方向各测点气泡个数分布最大值呈减小趋势,而其对应尺寸则呈现变大趋势;在靠近槽底,个数分布表现得比较集中,而在水面附近气泡个数分布曲线表现得低而平缓;实验条件下,整个断面上的气泡个数分布的最大值大体上出现在尺寸为0.5mm的地方;气泡平均尺寸在槽底处接近于0而朝水面方向迅速增大,且越接近掺气水流的水面,增加速度越快,最终趋于无穷大;气泡总数在掺气发展区内是沿程增加的,当掺气水流发展到一定程度后气泡总数就基本保持不变了;在同一断面上,各测点单位时间内的气泡总数随高度呈现出先增加后减小的趋势。

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。
