查询词典 wave

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.
