According to log lithofacies data base,the pattern was transrofmed into lithofacies by using pattern recognition,and then the lithological series column was formed.

Based on the research and practice of the support system, several issues were discussed such as digitizing the operating condition chart, designing the structure of information base for heat-power relationship, building the general calculation model for dispatch interval and performance index, determining the method of next-day power output project prediction, etc.

Effects of source-sink relationship between leaves and fruits on fruit characteristics of Cucumis melo;

Effects of type and application rate of nitrogen fertilizer on source-sink relationship in summer maize in North China Plain;

Advances and applications of research on source-sink relationship of rice

Effect of source-sink relation on grain filling properties of rice;

The optimal regulation of source-sink relation and main research means such as reducing source and thinning sink,isotope,biochemistry study,conducting tissue,crop simulation technique and population adjustment, hormone adjustment and fertilizer adjustment were reviewed.

The alteration of source-sink relation resulted in the noticeable changes of grain starch granule distribution in both cultivation conditions.
