丙烷

For people who complaining human rights, faky voices, air pollution in Beijing, please wake up and clear your mind, look at canada, CBC never broadcast anything supporting communist;secondly, our Toronto officers allows propane facility built 50 meters away from residents and the blast ruined so many people's house, why don't you say louder on those issues?

给那些抱怨北京人权、噪音好污染的人说，醒醒吧，清醒一下头脑，看看我们自己--加拿大，CBC从来不会报导***的任何好事其次，我们的多伦多**允许在离居民区50米远的区域兴建丙烷场所（注：应该是指有污染的吧，我也不知道具体怎么翻），而且这些气浪毁坏了如此多的居民住房，为什么不对自己的这些事情声音大一点呢

给那些抱怨北京人权、噪音好污染的人说，醒醒吧，清醒一下头脑，看看我们自己--加拿大，CBC从来不会报导GCD的任何好事其次，我们的多伦多ZF允许在离居民区50米远的区域兴建丙烷场所（注：应该是指有污染的吧，我也不知道具体怎么翻），而且这些气浪毁坏了如此多的居民住房，为什么不对自己的这些事情声音大一点呢

To test this hypothesis, we measured the effect of IV infusion of the NMDA blockers dizocilpine (MK-801) and-4-(3-phosphonopropyl) piperazine-2-carboxylic acid to decrease the MAC (the minimum alveolar concentration of anesthetic that prevents movement in 50% of subjects given a noxious stimulation) of 8 conventional anesthetics (cyclopropane, desflurane, enflurane, halothane, isoflurane, nitrous oxide, sevoflurane, and xenon) and 8 aromatic compounds (benzene, fluorobenzene, o-difluorobenzene, p-difluorobenzene, 1,2,4-trifluorobenzene, 1,3,5-trifluorobenzene, pentafluorobenzene, and hexafluorobenzene) and, for comparison, etomidate.

为了验证这个假说，我们检测静脉注射 NMDA 阻滞剂 MK-801和 CPP 来降低8种常规吸入麻醉药（环丙烷，地氟醚，安氟醚，氟烷，异氟醚，一氧化二氮，七氟醚和氙）和8种芳香族化合物（苯，氟苯，邻二氟苯，对二氟苯， 1，2，4-三氟苯， 1，3，5-三氟苯，五氟苯和六氟苯的 MAC 值，依托咪酯作为对照组。

Selective catalytic oxidation of propane has been a problem from the industrial point ofview because it is less expensive but difficult to functionalize.

丙烷作为重要的小分子烷烃，将其选择氧化制丙烯酸是一条很有前途的路线。

The OH functionality of the polyether may be controlled by using modifiers such as glycidol, ethylene glycol, water or trimethylol propane

用缩水甘油、乙二醇，水或三羟甲基丙烷等改良剂，可控制聚醚的羟基官能团。

The OH functionality of the polyether may be controlled by using modifiers such as glycidol, ethylene glycol, water, or trimethylol propane

可用缩水甘油，乙二醇，水或三羟甲基丙烷等改良剂，可控制聚醚的羟基官能团。

The first and second generation of dendritic polyesters have been prepared by divergent synthetic ways using trimethylopropame as core and o-phthalic anhydride, glycidol as branched units.

以三羟甲基丙烷为核，邻苯二甲酸酐，环氧丙醇为支化结构单元，合成了第一及第二代树枝状聚酯。

Both star copolymer precursors are hydrolyzed in the acidic conditions, then the corresponding recovered star copolymers of EO and glycidol with multi pending hydroxylmethyls are esterified with 2-bromoisobutyryl bromide to produce the ATRP macroinitiators with multi pending bromoisobutyryl groups . Then the latters initiate the polymerization of styrene to form the corresponding amphiphilic three- and four-arm star PEO-g-PS.

在阴离子共聚EPEE单体和环氧乙烷单体的过程中，通过变换引发剂体系中的醇的结构(由原来的二元醇变成多元醇，如三羟甲基丙烷和季戊四醇)，合成了星形结构的共聚物，通过水解反应脱去保护基团后，再与2-溴异丁酰溴反应，得到链的侧端挂有很多2-溴异丁酸酯基的星形大分子引发剂，通过ATRP聚合机理引发苯乙烯聚合得到PEO为主链，PS为侧链的星形一接枝共聚物。

Then the protected D-mannitol, mixed with lead tetraacetate, hippuric and acetic anhydride, were refluxed in THF for 18 h in a one-pot two step reaction to afford a chiral precursor-2-phenyl-4-[-2,3-O-]-propylidene-5(4H)-oxazolones.

产物与四乙酸铅、马尿酸、乙酐于THF中回流18 h完成一釜二步反应，纯化后得到含有手性碳原子的环丙烷氨基酸前体-2 苯基-4-[-2，3-O-]丙叉？

In gas phase, there are two reaction paths, the concerted and stepwise mechanisms, both of which produce the experimental product, hydroxamic acid; the stepwise mechanism is predominant.

在气相中均找到两条反应通道，即协同机理和分步机理，均生成实验产物氧肟酸，而且分步机理均为优势通道；除2-甲基-2-亚硝基丙烷的反应没有协同途径外，在溶剂中反应机理与气相中的类似。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
