应用泰勒展开式理论提出了一种求解溢流坝或闸下出流收缩水深的直接计算公式。文中给出了计算公式的证明,分析了其相应的误差并讨论了它在消能工计算方面的应用。用该式计算收缩水深具有直接计算的特点,省去了试算的麻烦同时作为应用,它又使得和收缩水深相关的消能工计算变得更为简单。可在水力设计中应用。

Applying Taylor expansion theory, a direct calculation formula for solving shrinkage depth of overflow spillway or sluice outlet is proposed. The paper gives the proof of calculation formula, analyzes its corresponding error and discusses its application in energy dissipation calculation. Calculating the depth of shrinkage using this formula has the direct calculation feature, eliminating the need for trial calculations as well as application, which in turn simplifies the calculation of energy dissipators associated with shrinking depths. Can be used in hydraulic design.
