According to the mechanism, olefin protonation is a process of acid-alkalireaction, so the reaction is easy to happen when the acidity of catalyst and the basicity of olefin are very strong.
按此机理，烯烃的质子化是酸碱反应过程。因此，催化剂的酸性和烯烃的碱性均较强时对反应是有利的。

The results show that there is a good relation between the expansion caused by alkali - silica reaction (ASR) and the water soluble alkali content or the effective alkali content.
结果显示，由碱硅酸反应（ASR）引起的膨胀与可溶性碱量和有效碱量之间有很好的关系。
