研究了一种基于声传感器的高精度管道长度在线测量方法。用含未知参数的有限维线性动力系统对直管中的驻波进行建模。计算未知参数候选参数的后验概率，通过对候选参数的期望得到管道长度的测量。为了实现高精度的在线测量，提出了选择驻波最佳模态的准则。(C) 2000 Elsevier Science Ltd.版权所有。
A highly accurate pipe length on-line measurement with acoustic sensor is considered. Stationary waves in straight pipes are modeled with a finite-dimensional linear dynamic system including unknown parameters. Posteriori probabilities of the candidates for the unknown parameters are calculated and pipe length measurement is obtained by taking expectation of the candidates. In order to realize a highly accurate on-line measurement, a criterion to select the optimal modes of the stationary wave is also presented. (C) 2000 Elsevier Science Ltd. All rights reserved.
