上海市纺织科学研究院于1987年7月承担了市经委下达的“防噪声耳塞中试研究”项目。经过两年多的努力,在小试的基础上,原材料全部国产化,建成了年产二百万付耳塞的生产线,并经纺织、机电、冶金等五十几家工厂数千名高噪声作业职工试戴,反映其性能良好,深受佩戴者欢迎。 该项目?

Shanghai Textile Research Institute in July 1987 assumed the Municipal Economic Commission issued the “anti-noise earplugs pilot project.” After more than two years of hard work, based on the small test, all the raw materials have been domestically manufactured and the production line with an annual output of 2 million earplugs has been built. Thousands of high-noise work in more than 50 factories including textile, electromechanical, metallurgy and so on Workers trying on, reflecting its good performance, welcomed by the wearer. this project?
