摘要
水的逐步商品化要求供水计量精度得到保证，特别是大流量的农业灌溉或工业供水尤显重要。大水港灌溉工程高干渠渠首无喉道量水槽的量水精度，采用明渠测流法进行精度鉴定，并在定量定性的基础上，评定量水槽的适用性。
The flow measurement precision is very important as water gradually commercialized especially for large flow agriculture irrigation and industry water supply. The precision identification has been made by open channel now measurement according to now measurement precision of non-throat flume in headwork of high main canal of the Dashuijiang irrigation project and the availability has also been evaluated based on quantitative and quantitative analysis.
