Lamb waves method is mainly used to characterize thin plate materials, without using very high frequency, it can measure the velocity of transverse wave and longitudinal wave, depth of the plate, and the bonding quality between plates.

• 兰姆波法主要用于表征薄板类材料，无需较高检测频率，可以测得板中纵波和横波的声速、板厚和板与板之间的结合特性等，检测精度较高。
