摘要
The production of radicals in the ozonolysis of ethene in air in a flow tube was monitored directly by a chemical amplification instrument at room temperature （298±2） K and 1 × 10^5 Pa. The radical yield is 0.50± 0.08 （σ） and found to be independent of CO. The result shows that the indirectly measured radical yields for the ozonolysis of ethene may be underestimated by a factor of 2.
