本文报道用近红外光谱预测汽油马达法辛烷值、研究法辛烷值和抗爆指数的方法。用多重线性回归和偏最小二乘法回归建立辛烷值的预测模型。基于此模型， 首次研制成功光学多道近红外辛烷值仪。
This paper reports a method for predicting octane number of gasoline motor by near infrared spectroscopy and studying octane number and antiknock index. Prediction model of octane number established by multiple linear regression and partial least squares regression. Based on this model, the optical multi-channel near-infrared octane meter was successfully developed for the first time.
