Lastly, through a three-layer frame and a cantilever beam testify that the method can very accurately identify structural damage location and degree.

最后，通过一个三层框架和一个悬臂梁的算例证明：组合参数法能够非常精确地识别出结构的损伤位置和损伤程度。

The results show that the method of canceling noise is better, and this grounds for the bug detection and location of damage identification.

结果表明，该方法消噪效果好，为损伤检测的缺陷定位分析打下了基础。
