Optimal algorithm of pressure measurement node layout in water distribution network 给水管网测压点的一种优化布置方法
Pressure tapping points on either side of the seat provide the means for flow measurement 阀座两侧的测压点提供流量测量的方法。
Compression site : the middle of the sternum and one - finger width below an imaginary line between the nipples 压点:用两只手指放在婴儿的乳线中点下一指宽位。
Additional exemplary features are the service - free vacuum pump and keypad with perceptible pressure points that is protected by a film from dust and moisture 无需保养的真空泵,键盘的按键具有可以明显感觉出的压点,并覆盖薄膜以防止灰尘和湿气进入等也都堪称样板。
A modified svm model was proposed and implicit function relationship between nodal pressures and pump station flow , pump station head was established based on modified svm model 本文提出了一种改进svm算法,并基于该算法建立了测压点压力和泵站流量、水头之间的隐式函数关系。
