It is proposed to study the quasi-liquid layer (QLL) that occurs on the surface of ice just below the melting temperature. This very basic surface melting phenomenon remains very imperfectly under- stood but is of considerable importance owing to the dominance of the water/ice system in nature. The extensive use of the freez- ing/melting process in the chemical industry adds an element of significant technological importance.

提出了研究冰面上略低于融化温度的准液态层的设想。这一非常基本的表面融化现象仍然没有得到很好的理解，但由于水/冰系统在自然界中的主导地位，它具有相当重要的意义。加料/熔炼工艺在化学工业中的广泛使用增加了一个具有重大技术重要性的元素。
