Ethanol's higher octane rating (around 96 compared with 91 for premium grade petrol) allows them to have a higher compression ratio-and thereby deliver more power as a result.
乙醇有更高的辛烷值(大约为96，相比而言，优质汽油的辛烷值为91)，这能使它们有更高的压缩比——因此，能释放更多的能量。
The higher the rating, the slower the burn when ignited during the compression burn cycle of the piston.
等级越高，输出的燃烧在压缩点火燃烧循环的活塞。
The results show that the rating curve established in this study can be applied to resilience method for determining the compression strength of the concrete in engineering structures.
结果表明该曲线精度高，置信度良好，可以直接应用于测定工程实际中的混凝土构件或结构的强度。
