利用一种新型的结合马赫-曾德干涉仪的生长装置，对在过冷水样品中生长的冰晶进行了原位观察。首先从观测到的冰晶干涉条纹的分布分析了冰枝的三维形态。从干涉条纹的图像中独立测量了两个不同的尖端半径和尖端生长速度，作为过冷的函数。在Langer和Muller-Krumbhaar枝晶生长理论的基础上，强调了冰枝晶三维模式形成的特征。
In-situ observations of ice crystals grown in a sample of supercooled water were conducted, using a new growth apparatus combined with a Mach-Zehnder interferometer. Three-dimensional patterns of ice dendrites were first analyzed from the distributions of interference fringes observed on the ice crystals. Two distinct tip radii in addition to the tip growth velocity were independently measured from the pictures of interference fringes as a function of supercooling. Characteristics of three-dimensional pattern formations of ice dendrites are emphasized on the basis of the Langer and Muller-Krumbhaar theory for dendritic growth.
