cetane number

To overcome the disadvantages of the linear calibration methods such as mlr and pls , least - squares support vector machine ( ls - svm ) is introduced to nir quantitative calibration in this thesis . for a set of diesel cetane number ( cn ) samples , the ls - svm model obtains the best performance in the cn prediction , compared with the mlr and pls model 為克服mlr與pls等線性校正方法的局限性,本文將最小二乘支持向量機( ls - svm )算法用于近紅外光譜的定量校正,并以一批柴油十六烷值樣品數據為例對以上方法進行了比較。

It is showed by research that it ' s cetane - value is so high that dme is perfectly suitable to be alternative fuel of diesel engine , and it is hopeful meeting the future stringent emission regulation of diesel engine because of it ' s clean combustion 研究表明, dme的十六烷值高,非常適合作為柴油機的代用燃料,而且它能實現潔凈燃燒,有望滿足未來嚴格的柴油機排放法規。

The significance , types and mechanism of diesel fuel octane improvers are introduced , and the characteristics of some typical cetane improvers are compared in detail 摘要就柴油十六烷值改進劑的種類、作用機理及其研制的重要意義做了綜述,介紹了部分十六烷值改進劑的性能特點。
