Three-phase embed electrode salt bath furnace use the salt class as heating impregnant, according to the different operating temperature, could select different ingredient salt or compound salt, the salt is not electric beforemelting, therefore the salt bath furnace must use the starting-electrode to melt when using, because the electricity bring quantity of heat unceasingly through electric dissolving salt, so can maintain the dissolving state, because of electrode under the electromagnetic effect,make the dissolving saltcycle unceasingly through natural convection and magnetism mix round,therefore can well-proportioned heat workpiece rapidly.

三项埋入式电极盐浴炉采用盐类作加热剂，根据不同的工作温度，可选用不同成份的盐或混合盐，盐在熔化前是不导电的，因此盐浴炉使用时必须使用起动电极溶化，由于电流通过导电的溶盐不断产生热量，故可保持溶化状态，因电极在电磁力的作用下，通过自然对流和电磁搅拌而使熔盐不断循环，故可迅速和均匀的加热工件。

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.
