这句译文很费解,其原因就在于译者没有弄清 in so far as 的确切含义。根据 Collins Dictionary 的解释, in so far as = in that = because。A Reference Grammar for Students of English 一书也作了这样的解释:
Our protest was successful, {in thatin so far as} the Minister agreed to reconsider the matter.
我们的抗议取得了胜利,因为部长同意重新考虑这件事。
再看下面的例句:
He can be trusted in so far as he has never yet told a lie. (ELD)
他是可以信任的,因为他从未说过谎。
此外, in so far as 还作“就……而言”, “在……程度上”(to the extent that) 解:
-
He is a Russian in so far as he was born in Russia, but he became a French citizen in 1920. (ALD) 就他出生于俄国而言,他是个俄国人,但他在1920年入了法国籍。
-
I'll help you in so far as I can. 我将尽力帮助你。
[试译]由于研究是保密的,所以这就必然会限制所有从事研究工作的人员同其它国家或大学的……科学家同行们进行有效的接触。
