The Ice Status Measurement Method Based on the Equivalent Resistance Difference Among Ice and Water and its Application In River Ice Cover Measurements

通过实验分析了冰在生长与消融过程中所表现出的电阻特性,提出了冰随温度变化呈现出的低阻区与高阻区现象.在此基础上介绍了"基于空气、冰与水的等效电阻值差异的冰情检测原理",以及基于这一原理设计的"R-T冰水情自动检测传感器",通过对传感器在中国北方地区黑龙江河河道冰情现场检测中的采集数据分析,提出了冰结构对冰等效电阻的影响效果.

This artical discusses the resistance characteristics of ice during its formation, growth and melting life cycle based on our experiemental research. We discovered that the resistance of ice falls into the low and high resistivity zones as the temperature changes.We therefore established our new research method of ＇ice status measurements based on the equiv- alent resistance difference among air, ice and water＇. Our ＇R-T ice and water measurement sensor＇ structure design is based on this new theory. Field researches have been conducted in the HeiLongJiang River in North East China. Data have been collected with the ＇R-T ice and water measurement sensor＇ and analyzed. Our analysis approved the influences of ice structure on the equivalent resistance difference of ice.
