This Summer, when Neves takes on Taunton native Mike Varner for the second time in three months at the Mohegan Sun Arena (Varner won the "Last Man Standing" MMA title in Fall River last December) Hawes and Harnois will have ringside seats, and in an upcoming episode of Ghost Hunters, so will Neves.

今年夏天，内韦斯时，需对风景如画的本土麦克varner为第二次在3个月内，在舞台上的莫黑根湖畔孙（ varner赢得了"最后的男子站在"甲基丙烯酸甲酯的标题在秋季河在去年12月）霍斯和阿尔努瓦将有ringside议席，并在在即将举行的插曲鬼猎人，所以将韦斯。

Poly(N-isopropylacrylamide-co-2-hydroxyethyl methacrylate)/clay hydrogel was copolymerized with NIPA and HEMA cross-linked by clay to form a new kind of nanocomposite hydrogel P(NIPA-co-HEMA)/clay was obtained.

以无机粘土为交联剂制备了具有温度、pH双重敏感性的聚(N-异丙基丙烯酰胺-co-甲基丙烯酸-β-羟乙酯)/粘土纳米复合水凝胶P(NIPA-co-HEMA/clay，并用红外和X衍射对其结构和形态进行了表征。

The current polymer materials for optical disc substrate usually include polycarbonate, poly, epoxy resins and noncrystalline cyclo-olefin copolymer developed in recent years.

光盘基板材料主要包括传统的聚碳酸酯、聚甲基丙烯酸甲酯、环氧树脂以及近年发展起来的非晶环烯烃聚合物。

For the first time ,AgBr organosol was obtained by using oleic acid to extract and modify the AgBr nanoparticles in hydrosol. And the optimum molar ratio of oleic acid to AgBr nanoparticles was found. AgBr nanoparticles, modified by oleic acid were mixed with MMA. After polymerization was carried out, the polymeric photochromic material was synthesized.

首次采用油酸萃取并包覆了水溶胶中的AgBr纳米粒子，制备了AgBr有机溶胶；并找到了萃取率最佳时的油酸与AgBr的摩尔比；再将油酸包覆的AgBr掺杂到甲基丙烯酸甲酯中，进行本体聚合，从而制备了AgBr光致变色有机玻璃。

By comparing the data of the photopolymerization of methyl methaerylate at 30℃ with those of benzoyl peroxide initiated polymerization at 60℃,it clearly shows that primary radical termination is more important at lower temperature than at higher temperature.

比较甲基丙烯酸甲酯在30℃的光引发聚合和在60℃的过氧化苯甲酰引发聚合的数据，可以看出，初级自由基的终止效应在低温时更为重要。

Then we tested the photosensitivity of POF whose core material was copolymer of azo-benzene and poly in experiment.

其次，对含偶氮苯和聚甲基丙烯酸甲酯共聚的纤芯材料的聚合物光纤光敏特性进行了实验测试。

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。
