喷入电弧等离子体射流对等离子体反应器流场的影响区域是近轴区，对过渡区和近壁区没有影响。

The arc-plasma jet in jested into the reactor exerted influences on the flow field in the hear-axis zone, while no influences in the transition and the near-wall zones.

实验表明：这类等离子体反应器中，旋流切向速度分量和轴向速度分量径向分布划分成近轴、过渡和近壁区。

The experimental results show that the tangential velocity and axial velocity components of the swirl flow along radial were divided into the near-axis, the transition and the near-wall zones.
