查询词典 bib nozzle

It is found that there is a critical value (25mm) for the distance from the nozzle to the skin surface when the spray time is 40 ms. If the distance is too far or too near, heat extraction process will have different characteristics. The results could provide an applicable method for guiding the Cryogen Spray Cooling of laser therapy.

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.
