International Thermonuclear Experimental Reactor ( ITER ) is one of the largest international cooperative projects following International Space Station. The purpose of it is to achieve nuclear fusion through isotopes of hydrogen : deuterium and tritium. 国际热核聚变实验反应堆(简称ITER)是继国际空间站等以来最大的国际合作项目之一,其目的是用氢的同位素氘和氚来实现核聚变。
In recent days Iran has also claimed it can match international technology in areas ranging from space launches to missile defence and the production of cancer-treating isotopes. 近几日,伊朗还宣称,从航天发射到导弹防御,再到治疗癌症的同位素生产上,伊朗都能够与国际技术相匹敌。
