The strategy involves a staged combustion, where a hydrocarbon fuel added in the second, fuel-rich stage provides hydrocarbon radicals which can react with and finally reduce the NOx formed in the first, fuel-lean stage, such that NOx formed in the first stage reacts with small hydrocarbon radicals present in the second stage combustion, finally leading to N〓, and to HCN which in turn is converted to NO or N〓. Understanding of the chemistry in this second reburning stage is clearly a key to understanding and optimizing reburn technology.

目前消除NOx的主要方法是向燃烧的废气中加入某些化学物质使其重新燃烧(Selective Noncatalytic Reduction of NO processes，SNCR)，RAPRENOx过程是SNCR的主要方式之一，其实施是向燃烧产生的废气中加入异氰酸，异氰酸在高温下经一系列包括NCO的自由基反应，可以从燃烧的废气中迅速除去NOx化合物。

Due to the ability to reduce radicals, CDH is suggested to reduced phenoxyl radicals produced in lignin degradation and prevent their repolymerization to promote lignin degradation by ligninases.

由于CDH具有还原各类自由基的能力，因此可以推测在木素降解过程中CDH可能起还原木素酶氧化的中间产物苯氧自由基，从而阻止其再聚合，推动了木素的降解。

Aging mechanism of wood-plastic composite was: light and heat break down the long molecular chains of wood flour and plastic; the free radicals reacted with the oxygen, which generated carbonyl groups, hydroperoxides and so on; the free radicals also had cross linking reaction, which generated alkoxy; Water destroyed the interface of wood flour and plastic, hydrolyzed ester additives, extracted the small molecule additives and degradation products; Microorganism degraded cellulose, semicellulose, lignin and ester additives; degradation product from different component accelerated the aging, which could be exampled by the fact that HCl from degradation of PVC accelerated the hydrolyzation of cellulose and semicellulose.

木塑复合材料的老化机理为：光和热引发木塑复合材料中木质组分和塑料组分大分子链断裂，产生的自由基与氧气作用，发生链支化反应生成羰基、氢过氧化物等，发生交联反应生成烷氧基等；水分破坏木-塑界面、水解酯类添加剂、抽提小分子添加剂和降解产物；微生物分解纤维素、半纤维素、木素和酯类添加剂；木塑复合材料中各组分的降解产物相互促进老化，PVC降解产生的HCl溶于水，促进了纤维素和半纤维素的水解。

Besides, Lb Gp2 is able to do away both the perocidating radicals occurring from the system of basic dimethyl sulphoxide and the hydrocarbon radicals coming from Fenton reaction, resuming a quantity-efficiency relationship.

此外，LbGp2能清除用碱性二甲基亚砜体系产生的过氧自由基和Fenton反应产生的羟基自由基，并呈量效关系。

Nine kinds of compounds from the connecting units and substitutional radicals (-NH_2、-N_3) substituting the tetrazine are designed and analysed their electronic structures, different radicals contribution to heat of formation, velocity and pressure of detonation.

American Heart Association has come to tea is "rich in eliminating free radicals, with the role of acid and flavonoids, one of the drinks, can reduce the incidence of myocardial infarction," the conclusions of the results of their research show that a particular cup of tea free radicals, the even more garlic, broccoli, carrots, cabbage can play a small role of acid-fast.

美国心脏学会曾经得出红茶是&富含能消除自由基，具有抗酸化作用的黄酮类化合物的饮料之一，能够使心肌梗塞的发病率降低&的结论，其研究成果表明，一杯红茶对特定的自由基来说，甚至比大蒜、西兰花、胡萝卜、小卷心菜更能发挥抗酸化作用。

The paper studied the scavenging active oxygen radicals of brown pigment from chestnut shell. The results showed that the brown pigment had scavenging effects on hydroxyl radical, superoxide anion radical and aliphatic radicals on lipid-peroxidation. In the range of test concentration, the maximum scavenging or inhibition rate of the brown pigment to hydroxyl radical generated by Fenton reaction, superoxide anion radical generated by illuminating riboflavin system and linoleic acid auto-oxidation was 83.0%, 82.1% and 88.5% respectively.
