The qualitative analysis and quantitative calculation about water surface curve is one of problems on non-uniform flow in water conservancy works.
使用计算机计算明渠恒定渐变流水面曲线有两种分法：恒定流方法和非恒定流方法。

应用该模型对矩形明渠中缓、急流过渡的水面曲线进行了数值计算，并与理论解进行了比较。
The model is applied to calculate the transition water surface profiles from supercritical to gradually varied flow or from gradually varied flow to supercritical flow in rectangular open channel.
人工渠道中的水流绝大多数是非均匀流，分析计算其水面曲线的变化规律是确定明渠边墙高度及回水淹没范围的重要依据，因此在工程实践中具有十分重要的意义。
Most of wter flow in open-channel or in river belongs to steady non-uniform flow. The surface profiles are caused by changes of channel section. It is very important to analyze its computations.
根据土水特征曲线可以确定非饱和土的强度、体应变和渗透系数，甚至可以确定地下水面以上水份分布。

Water flows through bend do a curve driving campaigns and the surface patterns and flow structures become adjusting and changing.
影响水面线及槽蓄曲线的因素可概括为河段自然地理状况及水流情势。
The factors affecting the water-surface profile and channel storage curve may be summarized as the physical geographical condition and the flow regime of the river reach.
例如，19世纪一个数学家的好奇心-叫做“空间-充满曲线”-一种早期的分形曲线-最近重新浮出水面，作为模拟人类基因组形状的模型。
For example, a 19th-century mathematical curiosity called the "space-filling curve" - a sort of early fractal curve - recently resurfaced as a model for the shape of the human genome.
根据水面波的正确图示法，推导出水面波的波形曲线方程是一条短幅旋轮线，这为旋轮线在力学中的应用提供了一个新例证。
