2) cross-section gauging flow
断面测流
1.
The simplified calculation of cross-section gauging flow which follows Prandtl\'s exponential distribution law is presented for miniature U-shaped canals based on the practice from the interior control of irrigation water in Ningxia WUA and some gauging flow cross-sections are established on miniature U-shaped canal by irrigation projects and maintenance of agricultural comprensive development.
针对宁夏项目区农民用水协会(WUA)组织内部实施量水到户遇到的实际问题,考虑到农业综合开发田间配套工程中已在农渠等小型U形渠道上修建了部分用于渠道量水的标准断面,提出了流速服从紊流型态的普朗特指数分布规律的小型U形渠道断面测流的简化方法以及相应的断面流量计算公式。
3) sectional flow monitoring
断面潮流监测
1.
An on-line sectional flow monitoring system of electric power grid is developed on GEN3-EMS platform,which realizes the definition of electric section operating rule base and the on-line operating s.
结合DSI调用特点对断面潮流监测流程进行了优化:将DSI的初始化过程和释放过程并入系统的启动和关闭过程中,而在系统监测定时器单元只执行DSI请求执行过程;采用参数值相等规则在DSI调用中只读取需要监测断面的线路遥测数据以减轻系统负荷;设置自动初始化和人工初始化功能以满足不同的需要。
4) metering section
测流断面，计量段
5) single line survey of river complete section of runoff
全断面一线测流法
