近年来， 臭氧层因受到消耗臭氧层化学物质（简称ODS）的损耗，而造成的平衡破坏、 浓度降低成为全球性的环保热点问题。

Ozone Layer was worn down by ODS recently, which resulted in the breaking of ozone layer′s balance and the decreasing of ozone layer′s thickness.

良好的环境控制系统：（1）于持续循环试验中，臭氧浓度仍能够快速达到平衡 （2） 测试槽具有自动持温功能。

Excellent system control: (1) Maintaining rapid resumption of O3 concentration during continuous circulation (2) With the ability of automatically and steadily keeping the chamber temperature.
