A portable precise instrument for measuring air density, which has higher precision and lower temperature drift, is introduced in this paper. 作者研制的便携式空气密度精密测量仪实现了高精度、低温漂的计量特性;
The air assisted spraying is the most mature techniques that can reduce drift. 气力辅助喷雾技术是目前世界上最为成熟的低漂移喷雾技术。
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;
Comparing with the traditional He Ne laser narrow beam collimating method, it has the advantages of the less influence of air disturb, minor light beam drift and high stability of the datum line. 与传统的He-Ne激光细光束准直法相比,这种方法受大气扰动的影响小,光束漂移小,准直基线的稳定性好。
Photorefractive surface electromagnetic wave ( PR SEW) at the interface between SBN crystal and air based on drift and diffusion mechanism was observed experimentally for the first time. 在实验中观察到扩散和漂移机理下在光折变晶体铌酸锶钡(SBN)与空气的界面形成的光折变表面电磁波。
The air assisted spraying technology, which greatly reduces the droplet drift, and has good adhesion, significantly reduces the risk of environmental pollution. 风送式喷雾技术由于减少了农药的雾滴漂移、增加了附着率,可使得环境污染的风险大大降低。
Also, an air gap flux observation of six-phase SM using voltage and current mixed model is presented, and a simple adaptive control scheme based on voltage and current of SM stator is proposed to compensate the drift of SM parameters. 建立了六相同步电机的电压、电流混合模型磁链观测方法,并针对电机参数随环境因素漂移问题,提出根据同步电机定子电压、电流自适应调整电机参数的方法。
