摘要
本文简要描述同位素示踪仪的设计原理。介绍了一种三芯测井电缆同时传递多个计数管脉冲信号的电路设计。单片机软件实现低功耗液晶多路显示电路设计也有创新。
A new ground water tracing instrument and its principle, features, and applications are described. Signals from G-M tubes are transported through a 3-wire cable. A low-power liquid crystal scan display circuit controlled by a microcomputer is employed. Both groundwater flow direction and velocity can be determined precisely. The instrument can be used in the survey of many parameters, such as coefficient of permeability, vertical flow, effective porosity, transmissivity, coefficient of dispersion and seepage of dam or reservoir bottom.
