摘　　要：采用近红外光谱测定了乙烯基硅油中的乙烯基质量分数，结果表明：在4600～4800cm。透射光强度与乙烯基质量分数符合比尔定律；该法可对乙烯基质量分数0．2％～5％范围的乙烯基硅油样品进行快速测定。The vinyl content in vinyl silicone oil was measured by near Infrared - spectra. Results showed that the transmission light intensity and vinyl content was between 4600 cm-1 and 4800 cm-1 comply with Beers＇ law. This method could determine the vinyl content of 0.2% - 5% in the vinyl silicone oil quickly and accurately.
