查询词典 milling of ores

According to the heavy-liquid separation test, the embedded granularity survey of tungsten minerals and shaking-table test of ore sample grading, the -0.7 mm granularity is determined to be selected for the gravity concentration test.

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.
