摘要

Ultrasonic nondestructive evaluation has two methods, linear and nonlinear. Research in the linear aspect is relatively abundant both domestically and internationally, and has achieved certain results and has been applied in production inspection. Nonlinear detection, however, is a new method that has developed in recent years and has attracted the attention of many scientists.
