For a set of gasoline samples , multivariate linear regression ( mlr ) and partial least squares ( pls ) calibration models are built to predict research octane number ( ron ) 針對一批實際生產裝置的汽油樣品,采用近紅外光譜定量分析中常用的多元線性回歸( mlr )與偏最小二乘( pls )方法,建立了汽油研究法辛烷值nir光譜預測模型。

However , the yield of gasoline was still low relative to the amount of petroleum processed , and the quality , as measured by octane number , was inadequate for high - performance engines 然而,相對于所消耗的石油來講,汽油的產量仍較低,而且其質量,以辛烷值的大小來衡量,也不適用于高性能的發動機。
