cracking的例句大全

The higher the absorbance ratio of Bronsted acid peak to Lewis acid peak ( i.e.AB/ AL) measured by infra-red absorption spectrum, the higher is the catalyst activity. The results show clearly that the Bronsted acid plays a dominant role in catalytic cracking reaction.

用红外光谱法测定了Bronsted酸峰与Lewis酸峰的吸光度（A）的比值，发现活性高的催化剂，其A B/A L值也高，说明在催化裂化反应中，Bronsted酸起主导作用。
