这样，依照实验方法，如果匹配的参考混合物由15%的正庚烷和85%异辛烷组成，那么按照所用的实验方法，对比实验样本的辛烷值就是85 。

Thus, if the matching reference blend is made up of 15% nheptane and 85% isooctane, the test sample is rated 85 motor or research octane number, according to the test method used.

两种基准参考燃料正庚烷和异辛烷分别被定义成辛烷值为0和辛烷值为100，将它们混合产生与实验样本相等敲缸强度的爆震。

Two primary standard reference fuels, normal heptane and iso-octane arbitrarily assigned 0 and 100 octane number, respectively, are then blended to produce the same knock intensity as the test sample.

结果发现，高辛烷值燃料异辛烷和高十六烷值燃料正庚烷的混合能够有效控制HCCI燃烧相位和燃烧程度。

The simulation suggested that the mixing with high-cetane fuel and high-octane fuel can influence the combustion phase and cylinder pressure in HCCI combustion.
