摘要

本文介绍低能X射线含沙量计的测量原理、测量方法、测量软件及误差分析。仪器的最小可测含沙量为0.072kg/m

，测量含沙量的标准误差为±0.024kg/m

。仪器探头的作用范周小于5cm，适用于临近河底含沙量的测量。

Abstract

The recent development of the sediment concentration gauge consisting of a

238

Pu low-energy X-ray source

a proportional counter and a microcomputer is reported. The measuring method and its software

as well as the error analyses

are given. The minimum measurable sediment concentration is as low as 0.072 kg/m

and the standard error is 0.024 kg/m

. The effective measuring range of the probe is less than 5 cm

so the gauge is suitable for measuring the concentration of the sediment near the bottom of a river.
