Relaxation Phenomena in Liquids and Glasses

这项研究是一项关于过冷液体和玻璃中出现的弛豫现象的性质的实验计划。介电磁化率测量将被用来研究最近在玻璃化转变附近的液体实验中看到的普遍行为的各个方面。计划进行比热实验，以寻找在热松弛过程中类似的普遍行为。玻璃态下的介电常数测量将被用来研究二次弛豫。同时，低温比热测量将与二次弛豫数据进行直接比较，以检查它们是否可以与目前的玻璃态理论相关联。计算机模拟将与这些实验研究并行进行。

This research is an experimental program concerned with the nature of relaxation phenomena that appear in supercooled liquids and glasses. Dielectric susceptibility measurements over 14 decadses in frequency will be utilized to investigate various aspects of universal behavior seen in recent experiments on liquids near the glass transition. Specific heat experiments are planned to search for similar universal behavior in the relaxation of the enthalpy. Dielectric susceptibility measurements in the glass state will be used to investigate secondary relaxation. In parallel, low temperature specific heat measurements will be made to make a direct comparison with the secondary relaxation data to check whether they can be related by current theories of the glassy state. Computer simulations will be carried out in parallel with these experimental studies.
