水流含沙量同位素监测系统

介绍了一种同位素含沙量监测系统。通过测量放射性透射得到的河水与吸收片的强度比率可求出河水中的含沙量。多个测量终端利用公用电话线将数据传输到主机进行分析处理，同时接受主机的控制。为克服放大器上的高压漂移与简化定标程序，在测量终端上设计了一种代替参考水箱的吸收片标定技术，并且在定标过程中采用了滑动平均的数学处理方法以降低随机误差。

Isotopic Monitoring System for Sediment Content in Water Flows

The sediment content in rivers can be determined by the count ratio of radioactivity transmitting through river water and absorbed by metal flakes. Under the control of a host computer, the measured data from terminals are transmitted through public telephone lines and processed by the host computer. In addition, a contrast calibrating system is designed for measuring terminals to overcome high pressure drift of amplifiers and to simplify the calibrating programs, and the moving average method is adopted to correct random errors.
