本文回顾了目前的知识气相溴光化学和大气溴物种的预算研究。通过考虑其链长和有效性，对涉及溴的臭氧催化损失循环的有效性进行了量化。链效率是一个新的变量，定义为链长度乘以循环的限速步骤的速率。链的有效性，使不同的催化循环，涉及具有非常不同的浓度的物种的公平比较。这一分析清楚地表明，在25公里以下，BrO/ClO和BrO/HO 2循环是最重要的臭氧破坏循环。
This paper reviews the current knowledge of gas phase bromine photochemistry and presents a budget study of atmospheric bromine species. The effectiveness of the ozone catalytic loss cycles involving bromine is quantified by considering their chain length and effectiveness. The chain effectiveness is a new variable defined as the chain length multiplied by the rate of the cycle's rate-limiting step. The chain effectiveness enables a fair comparison of different catalytic cycles involving species which have very different concentrations. This analysis clearly shows that below 25 km the BrO/ClO and BrO/HO2 cycles are among the most important ozone destruction cycles.
