1·Possibility reaction mechanism was proposed, which could be used to explain the spontaneous termination reaction in anionic polymerization of butadiene in the presence of polar additives.

对这些破坏活性中心的反应所提出来的反应机理，可以用于解释丁二烯阴离子聚合中的自发终止现象。

2·Siemens’s sluggish reaction to investigations in Liechtenstein triggered a letter last month from TI warning that the firm’s membership would be liable for termination after December 15th.

在列士敦士登的案件调查过程中，西门子还表现得十分不愿合作，上月招来了国际透明组织的警告信，称极有可能在12月15日后终止其成员资格。

3·Siemens's sluggish reaction to investigations in Liechtenstein triggered a letter last month from ti warning that the firm's membership would be liable for termination after December 15th.

西门子在列支敦士登调查中的反应迟缓更是激起了该组织的不满，在写给西门子的信中该组织警告说西门子将为12月5日之后其会员身份的终止负全部责任。

4·The coupling reaction produced 2 sulfradicals in a molecular chain of PAN with the length two times than that provided by other termination methods.
