- 中文摘要: A fluorescence monitoring system was used to measure gaseous sulfur dioxide at Taoyuan Agricultural Farm. A gas-diluting system and gas chromatograph equipped with a sulfur chemiluminescence detector used to audit the accuracy of diluted sulfur dioxide are described. The accuracy was-8% and -2%, respectively, for the preparation of 10 and 50ppb SO/sub 2/ standard gas. The pattern of variation of SO/sub 2/ concentration at Taoyuan Agricultural Farm is reported. In summer at Taoyuan Agricultural Farm, the concentration of SO/sub 2/ varied with a pattern of night concentration (15-20ppb) greater than that in the afternoon(0-2ppb). Computer-analyzed wind trajectories in Taiwan for this pattern are reported.
