利用2000至2002年的空气品质监测资料，计算研究对象受孕前一个月至分娩期间不同时期的周遭空气中悬浮微粒、二氧化硫、二氧化氮、臭氧、及一氧化碳等污染物的暴露情形。

The different adsorbed species such as sulfates sulfites and adsorbed sulfur dioxides under various temperature, pressure and evacuated treatment conditions were characterized by in situ-IR. In the absent of oxygen, two bands were observed at 1050cm〓 and 1330cm〓, the former is the weakly chemisorbed sulfur dioxide species and the latter is the strongly chemisorbed SO〓.

首次利用正电子淹没技术求取了CeO〓在MgAl〓O〓上单层分布的阈值为0.075g／gMgAl〓O〓，此值略小于利用XRD法求取的单层分布阈值0.08g／gMgAl〓O〓，并且发现催化剂的氧化吸硫活性，O-Ps的生成率与CeO〓的负载量之间良好的对应关系，当CeO〓在MgAl〓O〓上形成单层分布时，O-Ps的生成率最小，此时，催化剂的活性最优。
