Terminal oxidative inhibitors, such as KCN, Salicylhydroxamic acid , antimycin A and NaN〓, can cut off electron transport chains of cytochrome pathway and alternative pathway, marked decreased BADH protein levels. Oxidative phosphorylation uncoupler 2, 4-dinitrophenol had a similar negative effect on BADH gene expression, and exogenous ATP and ADP increased the BADH levels. These results, in conjunction with the terminal oxidation results, indicated that ATP could be a critical component in BADH gene expression.

2.2 末端氧化抑制剂KCN、SHAM、抗霉素A和NaN〓能打断呼吸链，阻断电子传递，使BADH蛋白的表达量明显降低，说明末端氧化同样参与BADH基因表达的调节：末端氧化影响基因表达的实质就是ATP的影响，线粒体磷酸化解偶联剂DNP明显降低BADH蛋白的含量，而外源的ATP和ADP对BADH基因表达的正效应作用最大。

In addition, we found that 4-phenyl-l,2,4-triazolinium N-ylides reacted withvarious electron-deficient olefins to afford pyrrole derivatives in good yields via 1,3-dipolar cycloaddition oxidative ring fission, In some cases, tetrahydropyrrolo[1,2-b]triazole and pyrrolo[1,2-b]triazole, which are stable and are not aromatized orcleaved in the reaction conditions, could be isolated, This is a facile and novel route forthe synthesis of pyrrole derivatives.

此外，本文研究了五员三氮杂环化合物4-苯基1，2，4-三氮唑的N-叶立德，发现在氧化剂存在下与缺电子烯烃发生1，3-偶极环加成反应生成的吡咯并[1，2-b]三氮唑，在大多数情况下开环生成吡咯衍生物，反应条件温和，收率良好，是合成吡咯衍生物的一个新的途径。

All ofthese reactions were carried out under mild conditions and are new effective methodsfor the preparation of indolizine derivatives. The reaction of phthalazinium and quinoxalinium N-ylides with electron-deficientolefins in the presence of oxidants have also been studied, it has been found that activemanganese dioxide could behave as a dehydrogenating oxidant. Pyrrolo[2,1-a]phthalazines and pyrrolo[1,2-a]quinoxalines are obtained in this way.

本文还对六员二氮杂环化合物酞嗪和喹喔啉的N-叶立德在氧化剂存在下与缺电子烯烃的l，3-偶极环加成反应作了研究，发现活性二氧化锰也是一个优良的氧化剂，并分别合成得到了吡咯并[2，1-a]酞嗪和吡咯并[1，2-a]喹喔啉衍生物。

Compound Ⅴ-3 has the largest two-photon absorption cross section and strongest two-photon induced fluorescence in these compounds because of its octupolar structure and the delocalized interaction among the chromophores.

由于化合物Ⅴ-3的八偶极分子结构和发色团之间的电子离域相互作用，它在三个化合物中有最大的双光子吸收截面和最强的双光子荧光。

Electron microscope observation showed that in group A the filter meshes and their fringes were clear and fragments of floccules could be seen occasionally. In group B the floccules scattered at fringes of the filter meshes and some meshes were obstructed by the floccules.

电子显微镜示A组网眼清晰，边缘清楚，偶见有块状过滤物，B组滤网有絮状物，散在分布于网眼边缘，模糊不清，堵塞网眼，表明有纤维蛋白聚集，血小板粘附，脱落形成血小板碎片。

加热系统采用加热炉，测温系统包括热电偶、电子电位差计、温度自动控制仪、自偶变压器等。

An improved OUR equipment was put forward in this paper, and was used in rest measurement. The effects of different environment conditions (temperature、substrate、heavy metal and uncoupled metabolism) to Yobs, YH and Kd were investigated systemically.

本文先提出一种改进的耗氧速率测量装置，以便用于后面实验数据的测量，然后系统研究了不同的环境条件(电子受体、温度、基质、重金属离子和化学解偶联剂等)对表观产率Yobs、真实产率YH以及衰减系数Kd产生的影响。

In view of their potential applications as electronic materials, the electronic structures of a series of PAMs are also investigated. The LUMO-HOMO gaps and the HOMO spatial distributions of the planar PAMs show obvious odd-even difference behavior.

电子结构分析表明，平面构型大环分子的LUMO-HOMO能隙和分子轨道空间分布具有明显的奇偶差异特性。

Control, and are responsible for the weather,the electrical system in the airport, and

你个人能控制机场的电子系统对天气负责，给偶留下了很深的印象。
