With the single-null divertor configuration on the HL-2A tokamak, the ray tracing and the wave power deposit for the ordinary electron cyclotron wave, perpendicularly injected from the weak field side, are analyzed.

在HL-2A单零偏滤器条件下，对由弱场侧沿赤道平面垂直注入的电子回旋寻常波的波迹和波的功率沉积剖面进行了分析计算。

The shock wave has made a nearly standard dodecahedron pattern on the surface of centre sphere. This pattern is the result of shock waves interaction from two adjacent detonating spots, and its position shows how the detonating of two adjacent spots acts, synchronized or not. The nice dodecahedron stroke patterns on the surface of recovered centre sphere indicate that this detonating method has good synchronization and spherical converging shock-wave.

通过试验，由十二个起爆点发出的爆轰波通过相互作用在回收球体的表面留下了近乎标准的正十二面体刻痕图案，球体表面的每一道刻痕都是相邻两个起爆点所发出的爆轰波相互作用的结果，每一道刻痕与相邻两个起爆点的位置关系反映了该两个起爆点的起爆同步性情况。
