In this thesis, the polymerization of triblock copolymer of styrene-butadiene-methyl methacrylate was carried out in glass flask ,with n-BuLi as initiator, 1,1-diphenylethylene as capping agent and Lithium 2(2-methoxyethoxy) ethoxide as additive.

本论文以n-BuLi为引发剂、1，1-二苯基乙烯为戴帽剂、2-(2-甲氧基乙氧基)乙氧基锂为添加剂，对玻璃聚合瓶中非极性-极性三嵌段共聚物聚苯乙烯—聚丁二烯—聚甲基丙烯酸甲酯的合成进行了研究。

Eudaemonist theories (Greek eudaimonia,"happiness") hold that ethics consists in some function or activity appropriate to man as a human being, and thus tend to emphasize the cultivation of virtue or excellence in the agent as the end of all action.

目的论的理论却有不同的最终性质的行动，应该推广。Eudaemonist 理论（希腊eudaimonia，&幸福&）认为，道德在某些职能或活动作为一个人适当的人组成，因此往往强调培养美德或卓越作为一切行动结束代理。
