摘　　要：The stable dislocation configuration in the surface layer of metals was calculated according to dislo-cation energy theory. It was shown that the stable dislocation configuration was only influenced by Burger's vector, while dislocation line could fluctuate closely around the direction vertical to free sur-face in a limited range.The stable dislocation configuration in the surface layer of metals was calculated according to dislocation energy theory.
