Hydroperoxyl

The theory of measuring hydroperoxyl radical by cavity ring-down spectroscopy

衰荡光谱法测量OH自由基的理论研究

High reductive radicals are generated by DC corona discharge at the presence of hydrogen as hydroperoxyl radical source , which can reduce CO2 to new organic molecules .

利用直流电晕放电，以氢气为自由基源产生强还原性自由基，还原C02，重新合成新的有机分子。

Hydroperoxidation of ethylene-propylene copolymer with ozone contained in oxygen stream was investigated . The effects of temperature , concentration , radical-generating agent , additive , and reaction time on hydroperoxyl content were studied .

本文研究了乙丙共聚物在含臭氧的氧气流中的过氧化氢基化反应，考察了温度、时间、浓度以及添加剂等对过氧化氢基化物（EPHP）中过氧化氢基含量的影响；

A wide absorption band in the region of 3200-3600 cm-1 attributed to the hydroperoxyl group was observed in the infrared absorption spectra of the polystyrene-hydroperoxide ; its absorption intensity became more marked with increasing HPO-value .

在过氧化氢基聚苯乙烯的红外光谱里，可以在3200&3600厘米~（-1）吸收区里观察到过氧化氢基的吸收带，其吸收强度随着HPO值的增大而加强。

The experiment results show that of the three natural compounds proanthocyanidins was found to be more efficient antioxidant . We discussed the reaction of antioxidant with hydroperoxyl radical ( HOO ) presented in the B-R oscillating system . 2 .

实验证明在这三种天然抗氧化剂中原花青素具有最强的抗氧化性。最后，我们讨论了在B-R振荡体系中抗氧化剂和过氧化氢自由基反应的机理。
