选择反应

I NEVER SAID DO THIS TO ALL THE PRESS, I SAID DO THIS TOTHESE TWO PEOPLE, LOOK AT THEM… not to all press but jus to them…..maybe I went a lil over the top but I never asked them to beat themdown, I was heated and I would never want ANY OF MY FANS to go to JAILor to do something STUPID so maybe now I will say this and change up mymeaning…… WHEN U SEE THESE TWO DOG MOTHERUCKERS PLEASE DISRESPECT THEMAS THEY HAVE DISRESPECTED ME……..

我再次强调，我所指的并不是所有传媒朋友，而只是个别的两位记者。可能我反应有点过敏，但我绝无意图怂恿大家去伤害他们。我曾经都被别人伤害过，所以我从不希望支持我的FANS因此而作出一些愚蠢的行为，或更甚要因此而入狱。故此，现在我要重新澄清我的意思，当你们见到这两位狗仔队记者，你们有权选择放弃尊重他们，如同他们不尊重我一样。

The ion mobility was measured at different temperatures and the effects of the temperature in drift tube on the variety and yield of the reactant ions and product ion s were discussed.

本研究在不同温度下进行了离子迁移率实验，结果表明，离子迁移率随温度的升高而增大，而提高工作温度可以减少水分子对产物离子的影响，有利于改善系统检测的分辨率；选择合适漂移管工作温度，能有效地增加反应物离子的产量，从而提高系统检测的灵敏度和选择性。

The results show that the ion mobility increases as temperature rises; the influence of water vapor on product ions was reduced and the system resolution was enhanced at a higher temperature. In addition, the reactant ion yield can be effectively increased by choosing a proper temperature in drift tube, and improves the sensitivity and selectivity of system.

The creative Mecca in Scandinavia right now is Gothenburg on the Swedish west coast, this is reflected on the choice of music for this compilation.

目前斯堪的那维亚的创造中心是位于瑞典西岸的Gothenburg，这正反应了他们在音乐编辑上的选择。

The main research work of this dissertation is as follows: Based on the chemical reaction engineering theory and the nitrobenzene electroreduction mechanism, the plate and frame electrolyzer was designed and applied to the process of electroreduction nitrobenzene to p-aminophenol. This dissertation measured the residence time distribution data of the electrolyzer by means of the pulse response method and studied the rule of flow pattern along with the current capacity change. Under different conditions ,this dissertation studied the cyclic voltammetry properties of nitrobenzene on different electrodes by means of the dynamic cyclic voltammetry method and the electrode materials applied to the NB electroreduction have been selected primarily.Baseed on the results of cyclic voltammetry tests, this dissertation used p-electrode systems to measure the steady-state- polarization curves of nitrobenzene on different electrodes in H-type diaphragm cell, and obtained each primary factor s influence rule and the exchange current density value of each electrode.And then on the basis of the conclusions of fundamental researchs upword, the effects of influence factors on the the yield of p-aminophenol and the current efficiency,such as electrode material, current density, quantity of electricity circulated, nitrobenzene concentration . sulpuric acid concentration and so on, have been studied in detail in the systems of hign temperature , strong acidity and oxygen-poorthrough a series of electrolysis experiments in this paper.After all using Pb as anode Monel metal as cathode Dupont Nafion 417 cation-exchange membrane as membrane, this dissertation obtained the optimum technological condition: reaction temperature about 85C, current density 500A m-2, sulphuric acid concentration 20%wt.
