简介：实验与1.5m和四个不同斜坡的经常的长度在一个2-dimentional水池上被执行。速度，雷纳兹压力和骚乱紧张的分布在这份报纸被学习了。结果证明当流动在出口斜坡上面继续，流动速度在隧道床附近增加，减少接近水表面。流动分离没被副词在床形式的冠观察。另外，分离地区的长度与增加入口和出口斜坡增加。最大值使正常化的最大的斜坡角度原因砍应力。基于实验，雷纳兹的形状强调分发通常依赖于入口和水池的出口斜坡，这被结束。另外，雷纳兹压力分发的形状被速度并且加速流动影响。随斜坡角度的增加，另外，第二等的水流被开发并且变得更稳定。在流动和床形式之间的动量主要被转由的象限分析表演的结果扫并且喷射事件。

简介：Lunnan()低在开发的地方，高举在奥陶纪和含碳的水库的冷凝物水池的数量，在北方定位Tarim盆高举，西北中国。自从喜玛拉雅的运动，Lunnan区域经历了集中的煤气的侵略，引起在奥陶纪水库共存的累积的多重类型。Geochemical证据证明这些冷凝物油具有低成熟(1.0%附近的vitrinite反射层次)，冷凝物气体的主导的部件是干燥气体(超过94%的CH4的内容)，它思考在Lunnan区域的冷凝物水池不是热裂开的产品，但是随后的累积源于阶段分别。而且，我们在Lunnan区域的C6-C7烃上的观察是类似于有比剩余油有更高的石蜡和更低的aromaticity的冷凝物的阶段分别的效果的品质上。因此，冷凝物的二种类型被他们的阶段行为定义，它是浸透的冷凝物水池和nonsaturated水池。有一枚油戒指的浸透的冷凝物水池主要在奥陶纪水库发展了，与形成压力(FMP)和露水点压力(DPP)之间的大差别。这些冷凝物的起源是被考虑在原处，分离由过多的干燥气体的侵略被触发。在另一方面，几乎在含碳的水库存在的nonsaturated冷凝物水池是包含FMP和DPP之间的细微差别的一座烃水库，没有油戒指，并且成为蒸气的分别由于差错运动控制它的产生。
