摘要(Abstract)：

近年来由于冰雪灾害导致的电网、公路结冰以及农作物和树木不堪重负而倒塌的现象频繁出现,对工程设施、交通运输和人民生命财产造成了直接破坏,所以对于冰融化过程的探究仍然值得关注。本文提出一种利用透射式太赫光谱系统探测冰融化过程的方法。当冰表面开始融化时,表面产生的水对太赫兹波有更强的吸收,且太赫兹波对于这一固液相的转变非常敏感。因此,可通过分析太赫兹透射信号峰值的强度下降速率了解冰表面融化状况。本文选取两种不同融化速率的物质作为实验样品,在常温22℃下进行融化实验,结果表明,纯水冻成的冰块的太赫兹透射信号强度的下降速率大于冰晶的下降速率,验证了冰晶盒具有良好的蓄冷作用。

关键词(KeyWords)： 太赫兹时域谱;冰融化速率;相转变
