河沙电特性与其含水量的关系

Relationship of river sand electric characteristics with its water content

本文利用数字电桥测量两种粒度不同含水量下河沙的电阻、电容和品质因数值,利用MT智能测水仪测量了其综合电特性,得到了两种粒度河沙的各单独电特性及综合电特性与其含水量的对应关系,为利用电特性测量不同粒度河沙的含水量提供了理论基础。

The resistance, capacitance, and quality factor of different granularity river sand were measured using a digital electric bridge and its synthetical electric characteristics were measured using an MT intelligent water-tester. The relationship of the respective electric characteristics, synthetical electric characteristics with its water content for different granularity river sand was obtained, which offers the theory for measuring the water content in different granularity river sand using its electric characteristics.
