Its verified that the knock signals of ionization currents are strong enough to be used for analysis of knock intensity and as a feedback signal for electronic-control.

由此证明了火花塞离子电流爆震信号可以用于爆震强度的评价分析，作为汽油机爆震电控的反馈信号。

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.

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。
