摘要
本文从分析压力管道水流流速分布规律出发,分别应用高斯和马尔柯夫数值计算方法,得出了矩形管道多声路超声波测流流量计算、声道分布座标及权重系数的数学模型,并用现场实测资料进行了验证。
By means of Gauss and Markov integration methods, the mathematical models of discharge computation, acoustic path, placement coordinates and weight coefficient are given for multi-path flow measurement of rectangled penstock. Also they are verified by the measured data got in field.
