急！！求帮忙翻译一段话，中译英

溢洪道的控制段之后常设置收缩段，并且溢洪道的水流一般为急流，因此，在收缩段内将产生陡冲击波，使溢洪道内水流的流态复杂化。收缩段的水流特征应采用冲击波理论分析计算，只有正常陡槽段的水力计算才可采用能量公式。分析表明，由于收缩段和正常泄槽段的相对水位不同，将产生不同的水面衔接形式。大多数情况下，收缩段的陡冲击波控制溢洪道陡槽的过流能力与边墙高度。

Answer 1

The control of spillway often set contraction in paragraph after paragraph, and the spillway flow is generally rapids, therefore, will have a steep contraction in paragraph shock waves, so that flow pattern inside the spillway complex. Flow characteristics of the convergent section should be used shock wave theory, analysis and calculation, only the normal hydraulic chute segment can be calculated using the energy equation. Analysis shows that, due to contraction in the normal chute segment and the relative level of different segments, will produce different forms of surface convergence. In most cases, the steep contraction segment control of the spillway chute shock wave over-current capability and side-wall height.
