接吻债券的检测和表征的方法，假设无论是压缩加载断裂面或污染层，进行了描述。通过传输设置用于提取窄带超声信号与非线性对接键相互作用产生的谐波。基于非线性界面刚度的时域模型用于预测实验结果。良好的定量协议被证明为压缩加载类型的接吻债券。
An approach to the detection and characterization of kissing bonds, assumed to be either compressively loaded fracture surfaces or contamination layers, is described. A through transmission set‐up is used to extract harmonics resulting from the interaction of a narrow‐band ultrasonic signal with a nonlinear kissing bond. A time‐domain model, based on a nonlinear interfacial stiffness, is used to predict the experimental results. Good quantitative agreement is demonstrated for the compressively loaded type of kissing bond.
