| 摘 要： | 水结冰和冰融化过程中的电阻、电容、温度物理参数与被检测冰表面以上的空气层或冰下水层的电阻、电容、温度有一定的差异,有些差异在数值上比较明显。基于这一特点,笔者提出了利用空气、冰与水的物理特性差异实现对冰层厚度及冰下水位接触式检测的新思路,对含有导电杂质的冰、冰-水混合物、水、空气的电阻、电容特性随温度的变化规律进行了初步分析,并得到冰的弱导电性质和冰与水的电容区间单调特性,据此提出了冰层厚度传感器结构及其冰厚检测原理,介绍了新型冰层厚度传感器在实践中的应用。

| Abstract: | As water freezes into ice and ice melts into water,evident difference will come into existence in its physical parameters such as resistance,capacitance and temperature between ice,measured air above ice layer measured and water below ice layer. According to the aforementioned features and basing a new the oretical framework of measurement on ice-thickness and beneath-ice-surface water levels by distinguishing the physical characteristics of air,ice and water,the paper analyzes the laws of the resistance and capacitance of ice with conductive impurity,mixture of ice and water,water and air change as temperature changes,draws conclusions such as ice as a weak conductor,monotonic feature of ice and water,and introduces the design of the structure of a new-type of ice-thickness sensor,its measurement method,and its application in practice. |
