The modified products have good anti-oxidation performance in low and hightemperaturerange.
改性后产物在低温到中高温温度范围内抗氧化性能 优良。

Those also make the crystallization of PET easier in the low temperaturerange, but more difficult in the hightemperaturerange.
阻燃剂的加入使PET的冷结晶容易进行,而从熔融态降温时的结晶过程变难。

Our approximate results for specific heat at the hightemperaturerange have the same temperature and volume dependence as that from the dynamical theory of crystal lattices.
