A new method of disease area mensuration and the percentage of diseases area of tea leaves with computer has been established by using Photoshop software to scan many leaves at the same time, and the further investigation also has been fulfilled. The results showed that when scanned with resolution 150 dpi,there were be short time to scanning and less disk space beenoccupied, and the effect as same as scanned with high -resolution. The results of disease area mensuration and percentage of diseases area of tea leaves using the new method also as same as the results using artificial mensuration, and the efficiency of the new method is much higher than the efficiency of artificial method.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
