英文摘要：

The concept of rough data was presented by employing S-rough sets having dynamic characteristic and the rough data law generation were given. Based on the concepts above, the generation theorem and the reversion theorem of rough data law, the recognition principle of rough data law and the discernible theorem of rough data law were given. The applications of rough data law were presented.
