| 摘 要： | 应用光声效应研究了聚双(对甲苯磺酸)-2,4-己二炔-1,6-二醇酯(PTS)在175—225K范围内的热学性质随温度的变化关系。发现比热C3和热导K的积C3·K在200K附近有一尖锐的峰,第一次由热学性质确定该处存在一个二阶相变。同时通过实验结果分析得到热导K在该温区内存在与温度成正比的反常行为,并对此作了分析。

| Abstract: | The thermal properties for PTS are studied by photoacoustic effect in temperature range 175-225 K. It is found that there is a peak of C3K at 200 K (here C3 and K are the specific heat and thermal conductivity of PTS, respectively), which shows crearly the existence of a second order phase transition in view of thermal propertis for the first lime. An anomalous thermal conductivity in the above temperature range is deduced from experiment results. |
