利用光声探测技术研究了硫脲和4，4 '-二氯二苯甲酮单分子晶体在160-210 K温度范围内的相变。第一，以及第二，阶相变观察。在Rosencwaig-Gersho和Korpiun-Tilgner模型的基础上对结果进行了讨论。
Phase transitions in a single molecular crystal of thiourea and 4,4’‐dichlorobenzophenone are investigated in the temperature range 160–210 K by means of photoacoustic detection. First, as well as second, order phase transitions are observed. The results are discussed on the basis of Rosencwaig–Gersho and Korpiun–Tilgner models.
