相变

Simulation result of the experiment shows that unloading and recovery process of PTCS is not consistent with the local stress redistribution and concentration.It can be divided into four phases:1.local stress unloads first in the middle of PTCS;2. stress continues to unload near the incident bar.3.Stress continues to unload near the transmission bar,the first and second layer PT buckling rumple disappear;4.the whole PTCS vibrates elastically.

对具体冲击实验的数值模拟结果表明：相变柱壳的卸载恢复过程在柱壳结构中是不均匀的，伴随着壳体局部应力释放和局部应力集中，可以分为以下四个阶段：1、柱壳中部发生弯曲变形的壳体应力首先释放，2、靠近入射杆端的壳体应力继续释放，3、靠近透射杆端的壳体应力释放，第一层与第二层相变屈曲皱褶消失，4、柱壳整体弹性振动。

T curve of the corresponding solvate trends towards the lower temperature A linear relationship was observed between the mol. vols. of the monohalogenated benzene and the Tc values of the corresponding solvates, with the only exception being the chlorobenzene analog. This anomaly is attributed to a first-order phase transition occurred around 185 K, which coincides with the Tc value of this solvate.
