Absolute rate constants for the reaction of ozone with dimethyl sulfide （DMS） were measured in a 200-L Teflon chamber over the temperature range of 283-353 K. Measurements were carried out using DMS in large excess over ozone of 10 to 1 or greater. Over the indicated temperature range, the data could be fit to the simple Arrhenius expression as kDMS = （9.96 ± 3.61） × 10^-11 exp （-（7309.7 ± 1098.2）/T） cm^3/（molecule.s）. A compared investigation of the reaction between ozone and ethene had a kC2H4 value of （1.35 ± 0.11） × 10^-18 cm^3/（molecule.s） at room temperature.

The sticking coefficients of ozone on ice surface and solid solution of sulfate and sulfide were measured over a temperature range from 200K to 260K. Experiments were performed in a horizontal flow tube. Results indicate that the sticking coefficients of ozone on ice are in the range from 1 3×10 -7 to 2 7×10 -6 , and it will become larger as temperature increases; the sticking coefficients of ozone on eight kinds of 0.1mol/L sulfate doped ice are in the range from 1 8×10 -7 to 6 9×10 -6 ; the sticking coefficients of ozone on four kinds of 0 1 mol/L sulfide doped ice are in the range from 3 2×10 -7 to 2 1×10 -5 . Ozone loss on these particles was evaluated.

The reaction probabilities of ClONO\-2 on ice surface were determined by using a flow tube reactor attached with a photoionization detector. The growth rate of HOCl was used to obtain reaction probabilities. The measured reaction probabilities depended on temperature and flow velocity. The reaction proceeded efficiently at temperature range of 190K to 200K. The reaction probability was 0 0023 at 198K ( v =100 cm/s). The result was in good agreement with that of Abbatt et al.

2006年3-11月期间利用2,4-二硝基苯肼涂敷的硅胶柱采集了北京市大气中的羰基化合物,并使用高效液相色谱（HPLC）的方法测定了甲醛及异戊二烯光氧化特征产物：甲基乙烯基酮（methyl vinyl ketone,MVK）和甲基丙烯醛（methacrolein,MACR）的大气浓度.研究发现北京市大气中MVK和MACR具有明显的季节变化和日变化：在植物生长季节的4-10月,可在大气中检测出MVK和MACR,它们在大气中的浓度（体积分数）的月平均范围分别为0.11×10^-9-0.67×10^-9和0.19×10^-9-1.36×10^-9,日最高浓度均出现在10：00-14：00（4月除外）,8月的浓度达到最高;3月和11月的大气中未检测出MVK和MACR,可能是因为植物处于枯叶期,异戊二烯的排放较少.本研究通过异戊二烯与其光氧化产物MVK、MACR和甲醛之间的转化产率关系,先利用测定的MVK和MACR的大气浓度反演在光氧化过程中损失的异戊二烯的大气浓度,然后估算异戊二烯光氧化对甲醛形成的贡献量.估算结果显示,4-10月,异戊二烯光氧化所产生的甲醛浓度（体积分数）范围为0.35×10^-9-2.50×10^-9,占北京市大气中甲醛总量（在大气中的体积分数范围为5.49×10^-9-22.04×10^-9）的4.6%-11.5%,在大气光化学活跃的夏季（6-8月）植物排放的异戊二烯对大气中甲醛贡献尤为显著.本研究证实了北京市区植物排放异戊二烯对大气光氧化剂形成有重要贡献.

设计并搭建了一个新的双反应器烟雾箱,用于研究可生成臭氧或二次有机气溶胶(SOAs)的大气氧化过程.该烟雾箱包括一个绝热的箱体及其内部两个体积为5 m3的氟化乙丙烯(FEP)薄膜反应器,箱内的温度可以精确控制在-10到40°C之间.利用该烟雾箱研究了光源对丙烯气相氧化机理的影响,发现相对于传统的黑光灯光源,采用的多重光源所得到的结果可以与模型更好地匹配.进行了丙烯和间二甲苯的光氧化的初步实验,发现该烟雾箱可用于模拟可产生臭氧或SOAs的气相氧化过程,并可以通过不同初始浓度的对比实验找寻不同物种对反应过程的影响.间二甲苯在不同NOx条件下光氧化得到的SOA产率与之前的研究比较符合,这表明该烟雾箱可以实现气-粒转化过程的模拟.双反应器可以实现在一个关键条件的存在区别,而其他条件完全一致的情况下的对比实验,从而帮助我们进一步理解在大气复合污染过程中起关键作用的因素.

运用静态箱法,对内蒙古乌梁素海不同水位的芦苇群落(Phragmites australis)和龙须眼子菜群落(Potamogeton pectinatus)的甲烷排放通量进行2a(2003～2004)野外观测.发现龙须眼子菜群落(沉水植物)甲烷平均排放速率为(3.44±1.60)mg.(m2.h)-1,仅为芦苇群落(挺水植物)的平均排放速率的21.94%.高水位芦苇的排放速率要大于低水位芦苇群落.芦苇群落的甲烷排放具有明显的季节性和日变化规律,并且5cm土壤温度和光合有效辐射分别是影响季节性和日变化的主要环境因子.根据观测数据和植物的分布面积,计算得出乌梁素海2003和2004年的甲烷排放量为1024.6t和1156.7t.
