中文摘要:
      文章叙述研制超声波浮泥重度测量仪的理论依据,介绍该仪器的电路设计原理.并给出了实验结果.该仪器主要在航道部门用于测定江河水底淤泥重度随深度的变化规律,从而判断是否需要对航道进行挖泥疏浚,以保证航道畅通.
英文摘要:
      Theory and circuit design of an ultrasonic fluid-mud bulk-density meter are discribed in this paper.Also experiment results of using this equipment to measure bulk-densities of different fluid mud samples are reported.This equipment is mainly used for measuring bulk-density of fluid-mud on river-bottom and deriving the profile of bulk-density with depth,and so it can be judged whether water way dredging needs to be done.
