Disposal on methyl orange solution by two kinds of nanometer sized iron oxyhydroxides:α-FeOOH and β-FeOOH in visible light showed that methyl orange solution decolored by 90% by FeOOH/H2O2 system.And phenyl in methyl orange molec...

用2种纳米氧氢氧化铁针铁矿，正方纤铁矿处理偶氮染料分子甲基橙溶液，在自然光下，FeOOH/H2O2体系能使甲基橙溶液脱色率达90%，并且能将甲基橙分子中的苯环部分打开。

With excessive nitric acid of different concentrations as the nitrating agent, regiospecific of meso-tetraphenylporphyrin were investigated in detail.

以不同浓度的硝酸为硝化试剂，详细考察了多种因素对meso-四苯基卟啉苯环上para位硝化反应的影响。

It has a promoting or inhibitory effect on the activity of soil enzymes at the early stage of application but assuaged or disappeared with time. Therefore, hydroquinone used as an urease inhibitor will not induce the pollution of environment and the poising of food chain.

但因其属于含有苯环的酚类物质，人们对其作为腺酶抑制剂在农业中应用的安全性十分关心，因为在我国和别的国家，均有过一些在短时期内不曾危害人类健康和生态

Inclusion complexes of α-,β-, and γ-CD with benzyldimetnyldodecyl ammonium bromide have been investigated by Uv-visible spectroscopy.

随着α-CD浓度的增加，BDDAB苯环上的紫外吸收峰强度增加。

This indicates that these HA have similar compositions, but different structures and properties.Results from analysing E465/E665 are the same as those obtained by analysing molecule structure using colour index coefficientΔ~ K.Compassion study of HA in NaOH and NaHCO_3 solutions show that the absorption peaks shift towards the direction of longer wavelength.

这几个吸收带的变化证明了以紫色潮土HA、石灰性黄壤HA、中性紫色HA、酸性紫色HA、腐殖土HA为序的腐殖酸的芳构化度降低、缩合程度下降的观象，说明腐殖土HA其分子在苯环C骨架的聚合程度、芳构化度和分子复杂程度等上均最小，与紫外光谱分析结果一致。

A new convenient synthesis of a series of 1-aryl-2-propanones using aromatic amines as precursors, via diazo reaction and improved Meerwein arylation reaction under mild conditions, was achieved. In addition, 1-[3,5-bisphenyl]-2-propanone is a new compound among the synthesized compounds. This approach is an efficient synthetic method for the aryl-propanones with the different substituting groups.

以芳香胺为原料，经重氮化和改进的Meerwein芳基取代反应，合成了一系列的1-芳基－2-丙酮，其中1-（3，5-二三氟甲基苯基）2-丙酮是一个新化合物改进后的方法简化了合成步骤，提高了收率，可方便地用于在苯环上具有不同取代基的芳基丙酮的合成。

The FTIR spectroscopic analysis reveals that the chemical structure of biomass has changed obviously after hydrogenating extraction in which the content of alkyls and aromatic structures obviously increased and the oxygen functional groups, mainly including carbonyls and hydroxys, decreased.

傅里叶变换红外光谱分析表明，经过加氢萃取，生物质的化学结构发生了明显的变化，饱和烃基和苯环结构增加，含氧官能团减少。

She was on BuSpar and clonazepam...

比思宁、苯环镇静剂

Industrial discharge of VOCs from the neighboring petroleum industrial parks was found to be the major sources of VOCs in the seawater of Kaohsiung Harbor. Due to the high toxicity and carcinogenic of chlorinated VOCs, strategies for the prevention and pollution control of VOCs from Kaohsiung Harbor should be developed.

由於含氯及含苯环类之挥发性有机化合物皆为毒性强之有害物质，且其因挥发性强，极易经由河面或港口海面逸散到空气中，可能对高雄都会区人民健康造成危害，因此有必要加强挥发性有机化合物污染源管制措施，以降低其对环境之危害。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
