Experiments were performed to clarify the melting characteristics of alcoholic ice-slurry stored for one night. In the first year, alcoholic ice-slurry was stored under two conditions ; (1) constant temperature slightly higher than the initial melting point temperature,. (2) periodic temperature varying between solid and liquid regions. The variations in crystal shape and size of ice were observed precisely, and the volumetric ratio of air, water and ice was measured along the height of the ice. layer. It was confirmed that the ice crystal at the top of the ice layer changes to a larger lump of ice through a storage of one night. The mechanism of the change was also clarified. In the second year, formation of "water path" in an ice layer through the melting process by a hot water shower from the top was investigated experimentally, based on the result of the first year. Processes of "water path" formation were clarified for the layer composed of uniform and non-uniform (larger one at the top) size of ice crystal.

通过实验研究了酒精冰浆在储存一夜后的融化特性。第一年，酒精冰浆在两种条件下储存：（1）略高于初始熔点温度的恒温; (2)在固体和液体区域之间的周期性温度变化。精确地观察了冰的晶体形状和大小的变化，并测量了空气、水和冰的体积比沿沿着冰的高度。层.据证实，冰层顶部的冰晶通过一夜的储存变成了更大的冰块。并阐明了这种变化的机制。第二年，在第一年结果的基础上，通过从顶部进行热水淋浴的融化过程，在冰层中形成“水路径”进行了实验研究。阐明了由均匀和不均匀（顶部较大）尺寸的冰晶组成的层中“水道”的形成过程。
