1.By the study of Flame Propagation Theory and Flame Stability Theory, backfire and yellow flame can be avoided by regulating the speed of flame propagation and exit velocity of mixture current at orifice.
通过对火焰传播理论和火焰稳定性理论的研究，综合调节火焰传播速度和火孔处混合气体的气流出口速度，不仅能保证煤制气燃烧时不回火而且燃烧完全，使黄火少甚至可以没有黄火。收藏指正
2.According to rigorous procedures, an experimental study was carried out to investigate the effects of jet exit velocity, flow direction, fluid subcooling and nozzle diameter on hysteresis of boiling heat transfer with impinging circular submerged jets of highly-wetting liquids.
摘要系统地研究了液体在圆形断面喷嘴浸没射流作用下沸腾热滞后与射流冲击速度大小、液体流动方向、液体过冷度和喷嘴直径等因素的影响。收藏指正
3.(2) When the guiding air curtain had the horizontal velocity, which opposites to the direction of the fluent field below the wind exit, then the droplet horizontal velocity would be reduced to improve the droplets deposition, thus drift could be lessened.
若风幕具有与其下方流场反方向的水平分速度,则可减慢雾滴水平方向运动速度,从而使雾滴有机会沉积下来,减小雾滴飘移的潜能;收藏指正
4.In order to separate gas and solid two phases completely, the velocity of particles at the exit of Laval nozzle should be high enough, therefore the Laval nozzle should be long enough.
??了更好地实现气、固两相分离，颗粒在缩放喷管出口处的速度应该足够大，因而缩放喷管就应该足够长。收藏指正
5.It is shown that with the decrease in size of particles, their velocity at the exit of Laval nozzle increases under the conditions of both the invariable gas parameters and the same Laval nozzle length; the Laval nozzle length increases with the size of particles under the same speeding rate of particles.
研究表明，在气流参数和缩放喷管长度不变的情况下，被气流拖曳的颗粒越大，颗粒在缩放喷管出口处的速度就越低；在颗粒加速率相同的情况下，颗粒越大，所需的喷管长度就越长。收藏指正
