Aided by the two virtual images of the seam light source on the seam plane observed at the back of the prism it can reach the systematic coaxis by regulating them to symmetrize the seam .

本文借助于在棱镜后面所观察到的在缝平面上的缝光源之二虚像，并通过把它们调至 对缝 严格 对称，迅速达到系统的共轴 要求。

The evolution properties of asymmetric laser filed in non-uniform and uniform plasmas are discussed and mechanisms that symmetric channel-like plasmas can confine the laser centroid around the plasma channel axes and symmetrize initially asymmetric laser beams are proposed ;
