Two factors weigh heavily against the effectiveness of scientific research in industry.One is the general atmosphere of secrecy in which it is carried out,the other the lack of freedom of the individual research worker.
新概念四中的句子.
in which it is carried out
一般认为是定语从句
那么其中的it指的是什么呢?

前文提到,有两个原因严重地妨碍着工业中科学研究的效率,名词为scientific research ,后面的句子中的it指的正是scientific research.
这句话等于就是
One is the general atmosphere of secrecy in which they carry it out.
显然,they是指“人们”,it指“科研工作”,即scientific research.
就像这个句子,People built the bridge in 1856,等于The bridge was built in 1856.
