Sixteen factors, which closely correlated with meteorological yield ratio of longan were selected from productive statistics and analysis of meteorological information in Licheng District(former Quanzhou City), main longan production areas of Fujian Province in 32 years (1961-1992) by the comparative expansion factor and stepwise regression method.

By "the average by linear glide" used to separation meteorological yield and path analysis on meteorological yield and meteorologica.

45% of total meteorological output of the product.

According to the actual publication of weather products,combining with the universal Web Services objectencapsulation technique,a solution is put forward and achieved,which publish weather products with Web Service technique to support multi-platform and seamless integration.

In order to thoroughly study the effect of mineral catalysis on the hydrocarbon generation of organic matter,the comparative experiments of whole rock and kerogen for 4 samples were completed under different temperature,respectively,by means of thermal simulating experiment in the open system.

It is very significant to determine the maturation threshold of primary hydrocarbon generation of source rock for evaluating the resource quantity of natural gas in gas-bearing basin and determining the primary period of hydrocarbon generation.
