摘要
以正交函数和超声波测流计算理论为基础，结合梯形断面流速分布规律，分别应用高斯和马尔柯夫数值计算方法，推导出梯形渠道多声道超声波测流流量计算、声道分布坐标及声道加权积分系数的数学模型。
Based on the theory of orthogonal functions and calculation of acoustic flow measurement,the mathematical models about discharge calculation,path distribution coordinates and weight coefficient of multiple path supersonic flow measurement in trapezoidal channel are obtained.by using Markov and Gauss numerical calculation methods respectively.The validity of these models has been proved by field data.
