No degradation occurred if the initial concentration of difenoconazole excessed 400mg/L in mineral salt medium.

基础盐培养基中，B2对初始浓度＞400mg／L的苯醚甲环唑几乎无降解作用。

METHODS: The vasodilatory effects of pinacidil and nifedipine were studied on rat aorta rings precontracted with 10 μmol·L -1 norepinephrine or 80 mmol·L -1 potassium chloride respectively.

大鼠离体主动脉环以10μmol·L－1去甲肾上腺素或80mmol·L－1KCl预收缩后，分别以不同浓度的吡那地尔和硝苯地平对抗。

Benzene molecule may be adsorbed on the surface of the roughened Rh electrode with a structure like 1,3- cyclohexadiene.

作为最简单的芳环化合物，苯是该方面研究的首选分子。

BP binds to AhR and subsequent translocates to the nucleus to activate the downstream gene expression, such as CYP1A1 and CYP1B1, to metabolite BP to benzopyrene-7,8- dihydrodiol-9,10-epoxide.

此外，过去研究文献指出苯芘的代谢活化是透过多环芳香烃受体而去启动下游代谢酵素CYP1A1、CYP1B1的基因转录活化，将其代谢成为benzopyrene-7，8- dihydrodiol-9，10-epoxide。

The results showed that Kaidimycin was chemically neutral, macrocylic polylactones, stable and liable to dissolve into water and pyridine, slight to dissolve into methanol, ethanol and N-butanol, difficult to dissolve into ethyl acetate, acetone, benzene and chloroform. Chemical reaction of functional group of Kaidimycin showed that it had glycoside, amino acid and aldehyde, no reducing sugar, polypeptide and phenol.

凯地菌素属中等极性的、中性抗生素，极性纸层析结果与多烯类抗生素的纸层析结果相似：易溶于水、吡啶，微溶于甲醇、乙醇、正丁醇，不溶于乙酸乙酯、丙酮、苯、三氯化碳；对高温、光照和紫外处理有很好的稳定性；官能团反应试验结果发现，凯地菌素可能含有糖苷键、氨基酸伯氨基和醛基，不含有还原糖、多肽和酚基，高锰酸钾、浓硫酸反应与多烯大环内酯类抗生素的特性相似；并且依据纯品，采用生物法和分光光度法对摇床发酵液进行了效价的测定。

Today started construction of a four items are: cyclohexanone 100,000 tons, 100,000 tons of refined crude benzene, 200,000 tons and 50,000 tons sulfuric acid amino acid and ancillary works, and other supporting projects will also be at full capacity next spring construction.

今天开始的四个项目的建设有：环己酮10万吨，10万精制粗苯，20万吨和5万吨硫酸氨基酸吨及附属工程，以及其他配套工程也将在满负荷将于明年春天建设。

In order to solve the problem of Botryosphaeria dothidea on resistance to traditional fungicides, bio-assay tests were made for 6 fungicides including 10% water-dispersible granules of difenoconazole, 250 gL^(-1) azoxystrobin suspension concentrate etc. against B. dothidea in laboratory. Field tests of these fungicides with different concentrations were made for control of the disease on apple trees.

为解决当前苹果轮纹病对传统药剂产生抗性问题，以70%代森锰锌可湿性粉剂为对照，在室内测试了10%苯醚甲环唑水分散粒剂，250gL^(-1)嘧菌酯悬浮剂等6种化学杀菌剂的室内毒力；另外在田间设置小区试验，测定了这些药剂在不同使用质量浓度条件下对苹果轮纹病的防治效果。

The mechanism of co-fluorescence effect has been discussed. In chapter six, the new fluorescence enhancement phenomenon was observed by adding some crown ethers to samarium-thenoyltrifluoroacetone system.

在第六章中，研究发现当向钐-噻吩甲酰三氟丙酮中加入配位能力很强的大环配体冠醚时，冠醚对稀土有机配合物体系产生显著的荧光增强作用，其中冠醚二苯并18冠6后（DB18C6）可使钐-TTA二元配合物体系荧光强度增强280倍。

A plausible process of this reaction is as following: Aldehyde was in equilibrium with the enol form, aldehyde reacted with aniline catalyzed by 2,2,2-trichloroacetic acid to afford imine, the generated imine immediately reacted with enol to form intermediate via intramolecular cyclization.

我们发现一分子芳基叠氮和一分子三苯基磷反应生成一分子磷亚胺，后者与由两分子取代的苯氧乙酰氯原位生成的烯酮反应生成4-亚烷基-β-烷基-内酰胺，其串联过程涉及烯酮亚胺的形成及其与烯酮的[2+2]的环加成反应。

Chloroacetic acid,chloromethyl ether,acetone,mphenylenediamine,butyl acetate,ethyl acetate,methylene chloride,ethylene dichloride,dioxane.

氯乙酸，氯甲醚，丙酮，间苯二胺，醋酸丁酯，醋酸乙酯，二氯甲烷，二氯乙烷，二氧六环。

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。
