Based on velocityuniformity in the outlet, the optimal elevation Angle has been determined.
根据出口速度均匀性，确定了最佳仰角。

With the increasing of axes distance, the droplets' velocity in the same section along the radius increased under the same voltage, and the velocityuniformity in the same section improved.
在任一电压下，随着射流轴向距离的增加，同一截面上雾滴速度都有所增加，且速度的均匀性沿轴向有所提高。

It is significant to find optional method for keeping the face velocityuniformity of FFU and reducing the face velocity turbulivity of FFU, furthermore, to keep the cleanliness level under FFUs.
