锐缘孔,锐缘孔口;
Considering some problems presently existing in the design of pressure rectangular conduit, this paper discusses about the optimum basis that the walls of the inlet section of a large cross-section rectangular pressuring conduit coincide the nappe of the relative sharp-edged rectangular orifice.
考虑到目前有压矩形泄水孔口设计中存在的一些问题,对大断面矩形有压管进口段的优化壁面拟合依据进行了探讨。
