摘要: Our understanding of the structure and properties liquids is in a much less well developed state than theory solids and, for that reason if no other, it difficult to give concise view subject. Simple like argon or sodium, which behave first approximation an assembly hard spherical atoms, can be treated reasonably satisfactorily by current methods but non–spherical nature water molecule leads molecular association liquid complicates problem immensely. In this book, primarily about ice, we shall concerned with only few aspects behaviour water; comprehensive discussion aqueous solutions would occupy several volumes. particular discuss views on at temperatures not too far removed from normal freezing point then go consider some detail phase transition involved freezing. The actual kinetics crystal growth will reserved chapter 5. Among reviews provide useful background are those Green (i960), Furukawa (1962), Barker (1963), Kavanau (1964) Pryde (1966). Experimental information case crystalline solid possible determine, diffraction methods, equilibrium positions vibrational amplitudes all atoms specifies crystal.
