近年来在一些新闻报道中时常会出现杯葛一词。如,“美欧各国为了反对苏联军队入侵阿富汗,于1980年杯葛了莫斯科奥运会。”“大陆方面对法向台湾战机一事进行了杯葛。”那么“杯葛”这个词的含义究竟足什么呢?原来“杯葛”同“坦克”“...近年来在一些新闻报道中时常会出现杯葛一词。如,“美欧各国为了反对苏联军队入侵阿富汗,于1980年杯葛了莫斯科奥运会。”“大陆方面对法向台湾战机一事进行了杯葛。”那么“杯葛”这个词的含义究竟足什么呢?原来“杯葛”同“坦克”“巧克力”等一样是一个音译外来词,来源于英语 boycott 一词。它在英语中作动词用时释意为(usu.of a group of people)to refuse to do business with(指一群人)抵制(贸易)或 to refuse to attend or take part in 拒绝出席或参加。其作名词时则表示 an act of BOYCOTTING(联合)抵制。(LongmanEnglish-Chinese dictionary of Contemporary English)。展开更多

We separated serum DBPs of mice by affinity chromatography with DNA-ceUu-lose column and analyzed them by sodium dodecvl sulfate-polvacrvlamide gel展开更多

The hydration of TBP has been studied by Karl-Fischer titration and IR spectroscopy. Recently, Ruddy found by tritium tracer technique that the species, such as TBP·H2O, （TBP·H2O）2, （TBP·H2O）4 and TBP·2H2O were present in the organic phase when TBP was equilibrated with water.展开更多
