In this research project number-size and morphological feature of stratosphericaerosolparticles were observed in the tropical stratosphere. The balloon-borne particle counter suggested that stratospheric particle distribution was certainly affected by active convection. According to electron microscopic measurements of the particles collected with a balloon-borne particle impactor showed that most of particulatematter were composed in sulfuric acid droplet suggesting that ineat sulfur diffused from the troposhere was converted to sulfuric acid particulate matter, as suggested by many investigators, through photochemical reactions in the stratosphere.The vertical profile of stratospheric ozone content showed the possibillity that ozone destruction through heterogeneous reaction occured in the lower ozone layr but not in tne main layr in the tropical stratosphere.The newly developed particle impactor was used in the measurements of stratospheric aerosols, in addition to the measurements of tropical stratospheric aerosols, in China, Arctic and Antarctic regions.

本研究在热带平流层观测了平流层气溶胶粒子的数量、大小和形态特征。球载粒子计数器表明平流层粒子分布肯定受到活跃对流的影响。用气球携带的微粒撞击器对收集到的微粒进行了电子显微镜测量，结果表明，大部分微粒是由硫酸液滴组成的，这表明，正如许多研究人员所提出的那样，从对流层扩散出来的硫通过平流层中的光化学反应转化为硫酸微粒。平流层臭氧含量垂直剖面表明，非均相反应破坏臭氧的可能发生在低层，而不发生在热带平流层的主层。除了在中国、北极和南极地区测量热带平流层气溶胶外，还将新研制的粒子撞击器用于测量平流层气溶胶。
