第075句:控制措施

Under modern conditions, this requires varying measures of centralized control and hence the help of specialized scientists such as economists and operational research experts

译文：

在现代条件下，这需要不同的集中控制措施，从而就需要获得专家的协助，诸如经济学家和运筹学研究专家等。

点睛：

该句的主干是this requires varying measures...and. the help。句首的under modem conditions为句子的状语。动词现在分词varying为measures的定语。and连接的是requires的并列宾语varying measures of...和the help...such as...则对specialized scientists进行了举例说明。economists and operational research experts意为“经济学家和运筹学研究专家”。
