相变

Cooling-curves of different composition after ultrasonic blend were measured with the guide of theory forecast results of the binary system of capric acid and myristic acid. The experiment phase diagram was protracted, eutectic temperature and composition range were discovered of the binary system. Phase change properties of eutectic composition were tested with DSC, the change of the wave shape of eutectic composition after 300 thermocycling was tested with IR.

The anisotropy inverted spectra will be determine, when the temperature reaches and goes beyond the temperature of phase transition for the NNPA and NIPA hydrogels that exhibit a LCST phase behaviors. The network is collapsed and the hydrated Cu ion is bound by network chains.

对于具有LCST相行为的NNPA 和NIPA水凝胶，当温度达到并超过其相转变温度时，即可测得其Cu自旋探针各向异性的ESR倒置谱，这种倒置谱是由于凝胶相变后，网格塌陷，网络缠裹水化Cu离子的结果。

According to DTA and the microstructure information, it is obtained that the phase transformation begins from 430.1℃,the solidus point of the alloy is 614.4℃, and the liquidus point is 636.4℃.
