摘要：
The structural difference, due to different precooling treatments and different amount of the sample, in glassy benzophenone, was calorimetrically studied. It was shown that, in the glasses precooled slowly, the structure involves 'the crystalline clusters' in which the molecules of benzophenone are packed more closely together than in the case of rapid precooling. Using the sample with mass of 2 mg, the critical cooling rate is to be found inside the range 20-15 K min(-1). (C) 2002 Elsevier Science B.V. All rights reserved.
