构造圈闭内沙四段产状平缓，储集层累计厚度大，含气丰度高。
The reservoir is thick with gentle occurrence and high gas abundance.
先后完成的黄河花园口至东坝头河段1988年中水丰沙型洪水及“92．8”高含沙洪水验证试验结果表明，采用本文提出的模型相似律进行模型设计，模型水流运动、泥沙运动及河床演变规律，均与原型相似。
The test results of this model for the floods of 1988 and 1992 show that the flow pattern, the sediment movement and the channel deformation all conform very well with the field data of these floods.
