Abstract：Some questions about Lamb waves in nondestructive testing of thin metal sheet were discussed in this paper. The calculation formula of energy distribution along thickness of sheet was advanced.It was shown that amplitude distribution of particle displacement could not be taken as the energy distribution and the uniformity of the energy distribution could not be used as principal criterion for optimum detection paramater. Furthermore,the generation of Lamb waves,the mechanism of the interaction between delamination and Lamb waves,the method of choosing optimum detection parameter were given primarily.
