Consequently, the vertical TEC around the receiving station was exported. Through this method, the vertical TEC got is an average value of a prick angle around the vertex. With the statistics of dispersion and the high precision data collected in Kunming station, the authors calculated the day by day time sequence value of total electron content in altiplano zone ionosphere. Based on this, they described the characteristics of TEC Sunday-changing in double-hump zone, comparing with CORS of Kunming.

It was revealed that the total cell density increased from early March to May, with a variation of 3 order of magnitudes in cell richness; Amphidinium britannicum and Adenoides eludens were two dominant species in the spring, however Gyrodinium viridescence and Peridinium quinquecorne might be abundant in the early summer; the cell density of dominant species inclined from the high-tide zone to middle- and low-tide zone. Finally, the importance of sonification treatment in precise cell enumeration of nature samples was discussed.

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.
