Analysis based on the experimental results demonstrated the plausible reaction mechanism is that vit C first converts Cu(superscript 2+) to its reduced state and vit C becomes vit C radical itself, thereby stimulating the formation of peroxyl and alkoxyl radicals, and bimolecular reaction of peroxyl radicals results in (superscript 1)O2 production in the systems studied.

根据实验观察的结果，分析了这一体系中(上标 1)O2形成的可能途迳，认为首先是维生素C将Cu(上标 2+)转变为还原态，而自身失去一个电子转变为维生素C自由基，从而刺激了过氧自由基和烷氧自由基的形成，过氧自由基的双分子反应很可能就是体系内(上标 1)O2产生的反应机制。

People always thought oxygen is beneficial hurtless to human body in the past, but from discovery SOD is had cleared exceed oxide after the action of freedom radical, the certain metabolization product that discovers oxygen (O2 ˙ or HO2 ˙, H2O2 and ˙ OH) and the active material of its ramification if fat kind cross oxidation child and single-track condition oxygen (˙ O2) can injure airframe.

过去人们总认为氧对人体是有益无害的，但自发现SOD具有清除超氧化物自由基的作用以后，发现氧的某些代谢产物（O2˙或HO2˙、H2O2与˙OH）以及其衍生物的活性物质如脂类过氧化产物与单线态氧（˙O2）可损伤机体。

This shows that Azolla has strong photosynthetic O2-releasing ability, which equilibrates the O2-CO2 concentration inside chamber in favor of human survival, and then verifies the prospect of Azolla in space application.

这说明红萍光合放O2能力很强，能有效促使密闭舱内O2、CO2浓度朝着有利于人生存环境方向平衡，进而验证红萍空间应用前景。

The results show that photocatalyst TiO2 improves the removal rate of toluene in not only the nitrogen plasma field (NTP-P-O2/N2) eradiating ultraviolet light but also the argon plasma field eradiating visible light. This supports the idea that both the UV light and the high-energy electron in the plasma field can activate TiO2. Furthermore, the toluene removal rate in NTP-P-Ar system is 5% higher than that in NTP-P-O2/N2 system, confirming that high-energy electron has greater effect on the degradation performance of toluene, as compared with UV light.

结果表明：在发射紫外光的氮等离子体场(NTP-P-O2/N2)中和发射可见光的氩等离子体场中，TiO2：均能提高体系的甲苯去除率，说明等离子体场中产生的紫外光和高能电子均能激活光催化剂TiO2；NTP-P-Ar体系中的甲苯去除率较NTP-P-O2/N2：体系中的约提高5%，说明等离子体场中高能粒子对甲苯降解性能的影响要强于紫外光的影响。

One way to interpret JCAHO'srecommendation is that 100% O2 should not be indiscriminatelyused, and anesthesia providers should have the ability, consistentwith patient needs and their clinical judgment, to deliver sub-100%O2 with nasal cannulae.

能解释 JCAHO 建议的一个原因为：100% O2不应滥用，麻醉者应有能力根据病人需要和临床诊断，通过鼻导管给予低于100%浓度的 O2。
