The heat transfer experiments were conducted on dropwise condensation of steam on the surfaces with gradient surface energy.

A detailed sequence dissection and multiple comparison of the domain-coding reg ions clearly showed that cereal germ lectin genes were evolved from a small ance stral gene (or a small truncated fragment) by two duplications, which resulted i n the modern form with four tandem-duplicated highly-homologous chitin-bindin g domains.

Using a DMT(Droplet Measurement Technologies) continuous flow streamwise thermal gradient cloud condensation nuclei(CCN) counter mounted on a Cheyenne ⅢA aircraft,aircraft measurements of CCN in about 20 flights over North China were conducted in the autumn of 2005 and spring of 2006.

Based on the cloud scheme of Chinese Academy of Meteorological Sciences(CAMS), awarm cloud model with prognostic variables of concentrations of aerosols,CCN and clouddrops was developed.

The distribution of aerosol,CCN concentration generally decreases with the height.

The results show that dust particles raised during duststorms increase the amount of large and giant cloud condensation nuclei in the atmosphere,lead to more large droplets activated at the early stage of cl.

The concentration of cloud condensation nuclei is determined from surface and aircraft measurements at Mt.

By using of high-speed photograph techniques,thermogravimetric analysis(TG),differential thermal analysis(DTA) and scanning electron microscope(SEM),the combustion process of fog aerosol and formation of condensation nucleus were investigated.
