| 1. | 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。 |
