查询词典 bib nozzle

The results show that the discharge and cooling stages of sparkjet were simulated by computational method. The instance energy input can produce the condition of high pressure and temperature in the actuator, which induce the forming of synthetic jet. With the increment of the input energy, the velocity of the synthetic jet could be increased to the supersonic state. Under the periodic energy input, the distribution of the sparkjet velocity on the nozzle is non-sinusoidal. And the discharge velocity of jet is much larger than the suction velocity of the flow from environment.

计算结果表明：采用本文的计算方法可以模拟出火花型激励器喷射、吸入的工作阶段；电火花瞬间能量的输入产生了腔体内的高温、高压环境，从而诱发合成射流的形成；当激励能量增加，激励器产生的合成射流速度增加，可达到超声速状态；周期性激励下，火花型合成喷喷口处的轴向平均速度随时间不是正弦分布，且喷射过程的最大速度要远远大于吸收过程的最大速度。

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.
