I used to be a member of a Muay Thai kickboxing/MMA club (I've moved to another city since then), and we would regularly get people coming in and checking out the gym.

我以前的一员，一个泰拳跆拳道/甲基丙烯酸甲酯俱乐部（我已经转移到另一个城市，自那时以来），我们会定期让人们未来在检查了健身房。

The induced supramolecular chirality was found to be dependent on the absolute configuration of lateral residues, that is, the polymers with-configurational oxazolinyl chromophores tended to form chiral aggregates with levorotatory handedness, while polymers obtained from the-monomer offered dextrogyrate one upon the addition of Cu salt. A model, in which side groups would arrange in a helix fashion, is employed for describing the unusual chirality.

由此提出了侧基在Zn／Cu协同配位作用下形成螺旋状排列的模型，即侧基螺旋模型。N-噁唑啉苯基马来酰亚胺与甲基丙烯酸甲酯共聚得到了耐热性能好(热分解温度大于296℃)的光学活性聚合物~(25D=-7.8°(来源：Af4BC论文网www.abclunwen.com)～-36.6°。

A steel bar is washed and dried, and then put into a glass pipe which is sealed to obtain stirring magneton; a mixed solvent of Gamma-methacrylate oxide propyl trimethoxy silane and methanol is prepared and added with an organic base to obtain a pre-bonding solvent; the stirring magneton is immerged into the pre-bounding solvent, and the outer surface of the glass pipe of the stirring magneton is bonded with a layer of silane substance with alkenyl; a reactive monomer mixture and a pore-forming agent mixed solvent are evenly mixed and then added into a container, the stirring magneton after the pre-bounding is put into the container which is sealed and then put into a water bath; after reaction, the container is removed, the stirring magneton coated with a polymer is taken out and put into a extractor and extracted by using a solvent; or the stir bar is immersed into the solvent till no impurity can be checked in the solvent, thereby obtaining the product.

将铁条清洗干燥，放入玻璃管内，密封得搅拌磁子；配制γ-甲基丙烯酸氧丙基三甲氧基硅烷与甲醇的混合溶液，加入有机碱得预键合溶液，将搅拌磁子浸入预键合溶液，在搅拌磁子的玻璃管外壁键合一层带烯基的硅烷化物质；将反应单体混合剂和致孔剂混合溶液混匀后倒入容器中，将预键合后的搅拌磁子放入容器，密封后置于水浴中，反应后除去容器，取出涂有聚合物的搅拌磁子，置于提取器中，以溶剂提取，或将搅拌棒置于溶剂中浸泡至溶剂中无杂质检出，得产物。

Next, the proximal 10 cm of the femur was stripped of all soft tissues, and the marrow cavity was packed with polymethylmethacrylate.

接下来，剥离肌骨近端10cm的所有软组织，髓腔用聚甲基丙烯酸甲酯填充。

The research indicated that under the compound use of hydroquinone and methyl quinone or independent use of phenothiazines or nitrogen oxygen free radical made the polymerization retarder, opposite-methyl-phenylsulfon made the esterification catalyst, toluol made the backflow including water condition, the acid mellowly compared to when it was 1.15, the production rate of the synthesis methylacrylic acid polyethylene glycol single methyl ether (400) ester may achieve 98.9%, was extremely similar to the overseas product functional group structure.

研究表明，在氢醌、甲醌复合使用或者单独使用吩噻嗪、氮氧自由基哌啶酮作阻聚剂，对甲苯磺酸作酯化催化剂、甲苯作回流带水的条件下、酸醇比为1.5时，合成的甲基丙烯酸聚乙二醇单甲醚(400)酯产率可以达到98.9%，与国外产品官能团结构十分相似。

The bulk photopolymerization of methyl methacrylate at 30℃ was studied.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
