The results show that the metal stannate combined with Mg2 can be used as a highly effective flame retardant for flexible PVC, and it can be seen that the Mg2 enhances the flame retardant properties of the samples through the endothermic dehydration, the stannate may act in both the condensed and vapor phases, but mainly in the condensed phase as a Lewis acid.

结果表明：锡酸盐和Mg2复合使用能明显提高对软PVC的阻燃效率，Mg2主要通过脱水吸热作用使材料的阻燃性能提高，而锡酸盐可分别在凝聚相和气和起作用，但主要为凝聚相Lewis酸催化机理。

The reactions are all exothermic due to the participation of the metal ions, to be compared with the strong endothermic process of the unimolecular CO2 decomposition.

因为有金属离子的参与，使单分子CO2的强吸热分解反应变为生成CO和MO的放热过程。

At present, solar vacuum tube The ratio of heat in 93.5%, while other solar water heating systems in the thermal efficiency is about 50 percent.

目前，太阳能真空管的吸热比率在93.5％，而其他太阳能热水系统的热效率却在50％左右。

The four reaction channels including hydroxyl-type benzaldoxime are endothermic reaction, thermodynamically non-spontaneous process, but the other four reaction channels including ion-type benzaldoxime participation are exothermic reaction and thermodynamically spontaneous process. The latter four reaction channels, which have lower reaction barriers, faster reaction velocities and bigger equilibrium constants than those of the former fours, are the chief reaction channels.

苯甲醛肟以羟基型参与反应的4个反应通道均为吸热反应和热力学非自发过程，它们均具有较高的反应势垒、较慢的反应速率和较小的平衡常数；而以离子型参与反应的四个反应通道均为放热反应和热力学自发过程，它们的反应势垒较低，反应速度较快，平衡常数也较大，故苯甲醛肟应主要以离子型参与反应。

The thermodynamics quantities were calculated based on the first relaxation process. The results indicated that active enthalpy△H and active entropy △S all decreased with the increase of decrystallization extent. And, it was concluded that the relaxation process of untreated wood is for endothermic reaction and that of treated wood for exothermic reaction.

并通过计算获得了第一个松弛过程的各个热力学量，活化焓△H和活化熵△S都随着非晶化处理程度的增加而减小，未处理木材的松弛过程为吸热反应，而处理木材的松弛过程为放热反应。
