求翻译：因而从理论上分析，只要管道的几何形状中包含下降-上升通道，就会在两者交汇处形成液塞，液体粘性、表面张力等因素会影响到液塞的形成方式和液塞的几何形状。是什么意思？

Thus from the theoretical analysis, as long as the geometry of the pipeline include drop - rising channel, will form a slug in the two interchanges, liquid viscosity, surface tension and other factors will affect the way the slug formation and slug geometry .

Therefore, as long as pipelines from theoretical analysis in the geometric shapes that contains drop - increased by channel, it will be in the interchange, forms the liquid liquid viscosity, surface tension and other factors may affect the formation of the liquid and fluid manner the geometry.

Thus theoretically analyzes, so long as in the pipeline geometry shape contains the drop - rise channel, can form the fluid in both intersection point to fill, the geometry shape which to the fluid factors and so on liquid coherency, surface tension can affect which fills the mode of formation and t

Thus in theory analysis, as long as the falling-rising channels included in the geometry of the pipeline, there will be a junction of the two form a slug, liquid viscosity, surface tension and other factors can affect the way to the formation of liquid slug and slug of geometric shapes.
