摘要：
In this study parallel steel rods which served for both time-domain reflectometry (TDR) measurement of liquid water content and for conductance measurement were installed in three soils and monitored regularly during winter. The study shows a close correlation between simultaneous determinations of electrical conductance and TDR measured water content. Rapid changes in both parameters took place during freezing and thawing. 14 Refs.
