It shows that the adjacent synthetic jet flow field is affected by the phase - difference , amplitude and frequency of two actuators , and the synthetic jet is asymmetric and turning when they are working differently . the main reasons result with the asymmetry and the interaction between the two adjacent synthetic jets , leading to the formation of " low pressure closed circumfluence region " , which is also called entrainment field , and the synthetic jet turns to the region where the pressure is lower and the vorticity magnitude is higher 当两相邻激励器处于不同工作状态同时工作时，合成射流将发生偏转，其主要机理是由于两激励器吸入和排出流体流动不同，使得两列旋涡对不对称，在两列旋涡对之间存在“卷吸场”和压强梯度，从而引起旋涡对向低压侧和强涡量区偏转。
Yet for thickness shear actuators , due to the shear deformation dominates the plate deflection for shear actuation mechanism , the higher order shear theory can provide more accurate evaluation of the shear strain energy of the plate than the first - order one , higher order shear deformation theory can provide more accurate evaluation of the deformation of the plate 但对于厚度剪切型激励器而言，由于激励器主要是引起板的剪切变形，而高阶剪切变形理论比一阶剪切变形理论能更好地反映结构的剪切应变能，因此高阶剪切变形理论可以提供板变形的更为精确的解。

And the technology can also control the vector of a primary jet , the ratio of momentum between the synthetic jet and the primary jet is a main influence factor , and the vectoring control of primary jet is also effected deeply by the position and the frequency of actuators 应用合成射流技术可以有效控制宏观低速流流动方向，其控制强度由宏国防科学技术大学研究生院学位论文观流动与合成射流的动量比决定，而合成射流激励器的工作频率以其布置位置对主流的控制效果影响很大。
