叙述了窄缝坎挑流的水流特性、消能标准及其体型尺寸L0，β，b,B的选择。试验提供了不同β与θ2变化的试验成果，及水舌纵向拉开值的估算式。试验值与计算值较为接近，可供设计者参考。

The flow characteristics,energy dissipation standard and the selection of size of configuration such as L0,β,b and B are described. The test data of θ2 varying with β and an estimation formula of longitudinally extended width of jet are given in the paper. The computed values approximate to the test data. The data provided may be used as reference for designers.
