But the effluent ammonium in the anoxic reactor, where enough NO2 present were present, was equal to the blank system, and no ammonium was converted to such nitrogen compounds as NO-2 and N2 by Nitrosomonas eutropha using NO2 as electron acceptor, which maybe caused by lack of the function bacteria.

但在足够NO2存在并且缺氧的条件下，单级自养脱氮系统内的出水氨氮浓度与空白反应器相当，NH+4并没有被亚硝化单胞菌以NO2为电子受体氧化为NO-2和N2等化合物而得以去除，可能是因为系统内不存在该类型的亚硝化功能菌。

Herein, we synthesized six metalloporphyrins linked with stable nitroxyl radials, and evaluated their catalytic activity for the oxidation of glycosyl sulfides to glycosyl sulfoxides.

本论文设计、合成了6个连有稳定氮氧自由基的卟啉及其铁、锰的络合物，考察了它们对糖基硫苷等硫醚类化合物氧化成亚砜的催化性能。

In a DMF solution of CuCl〓-ethanolamine-acetic acid (1: 2: 2), 27 formed a highly oxidized heterocyclic compound 2-hydroxymethyl-naphtho [1, 2-a] oxazole (30) by the carbon-nitrogen coupling and carbon-oxygen coupling with the ligand of ethanolamine, which brings a chance to develop a novel approach to this heterocyclic compound via one-pot reaction of phenols under mild condition.

在氯化铜—乙醇胺—乙酸（1：2：2）的DMF溶液中，27与配体乙醇胺发生碳氮偶合与碳氧偶合，生成深度氧化的杂环化合物：2-羟甲基-萘并[1，2-a]〓唑（30）。这可望为酚类一锅化直接转化为30及其类似物提供一种简便的新合成路线。

Any of various acids containing the peroxy group.

氧和另一种元素或基形成的化合物。

One of the active ingredient a compound, Peroxy Acid discovered by Dr. Ciccarelli, has been tested and proven to ease existing pigmentation, prevent formation of new pigmentation as well as to lighten the skin effectively.

一有效成分化合物， Ciccarelli博士发现的过氧的酸，被测试了，并且证明缓和现有的染色，防止新的染色的形成并且有效地照亮皮肤。

Ten variously substituted benzoyl peroxides were synthesized for Raman spectrometric identification both in solution (CCl 2FCClF 2) and solid state. Different to infrared spectra, Raman spectra have been proved to be a useful characterization of the highly symmetric peroxy bond in diacyl peroxides. The ν OO value ranged from 850 to 899 cm -1 varies regularly with the substituent on the phenyl ring.

合成了全氟和其它对位、间位取代的共10种过氧化苯甲酰，测定了它们的固体和溶液(溶剂为F113， CCl2FCClF2)的激光拉曼光谱，首次发现这类化合物中高度对称的过氧键有较强的特征谱带，即νOO在850至899 cm-1之间，并随取代基不同而呈现规律变化。

A compound, such as sodium peroxide, Na2O 2, that contains a peroxyl group and yields hydrogen peroxide when treated with an acid.

过氧化物：一种包含一个过氧团离子的化合物，Na2O 2，遇酸可生成过氧化氢，如过氧化钠

This result again showed that in the process of the reaction of flavonoidswith α-hydroxy ethyl peroxyl radicals, 2,3-double bond in the C ring of flavonoidsplays a more important role than o-dihydroxy in the B ring.

这进一步说明了黄酮类化合物与有机过氧自由基反应的过程中C环2，3双键比B环邻二羟基起着更重要的作用。

It can beconcluded from the experimental results that in the reaction of flavonoids withα-hydroxy ethyl peroxyl radicals, 2,3-double bond in the C ring plays a moreimportant role than o-dihydroxy in the B ring.

从实验结果来看，在黄酮类化合物与有机过氧自由基反应的过程中，其分子结构中起主要作用的是C环2，3双键，而不是B环的邻二羟基。

For flavonoids containing 2,3-doublebond in their C ring, peroxyl radicals mainly add on the double bond, and the adductsmay transfer to the final products through short chain reactions, which results in theincrease of G values of hydrogen peroxide.

根据实验结果我们认为黄酮类化合物与过氧自由基的反应是加成与电子转移的混合反应。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
