摘要
本文对孔板消能形式，通过系列试验研究，确定出较为理想的孔板孔口形状及各种异形孔板串联消能的最佳组合，对孔板消能提出了新论点。
Energy consumption with step orificeplates is being used in hydraulic engineering. There are some design problems,however,which have not beensolved completely;practical tata are also sortage. In this paper,the forms,the efficiency of energy consumption of orificeplates and the relationships between it andits flow capacity are investigated.Through a series of experiments and study oncombinations of its various forms,the new thesis of orificeplates energy consumption is proposed.
