摘要: The role of various types lattice flaws is discussed in their bearing on melting and crystal structure. Freezing-point determinations lattices a single molecule indicate the presence such crystals polymethylene compounds. composite ketone + paraffin emphasize importance rotation CO group for melting, that holes are easily formed, without marked lowering freezing-point. Ordered formed when number does not exceed 12% all methylene groups. results co-operative effects flaws. In equilibrium state crystal, might arise both from energy at 0 degrees K, expecially metals, entropy higher temperatures. A picture suggested which network breaks up into mosaic, or aggregate crystalline micelles, solid-liquid transition comparable with gel-sol transition.
