This method which is proved workable by the experiment can identify the dimension tolerance that whether it is between the promising tolerance band. The analysis of cross correlation ; workpeice ; detection

本文借助在测试技术领域中常用的互相关分析法，该方法在流速流量的测量、管道泄漏检测等方面的应用较多【31，但目前将其应用在工件检测方面的研究较少。

The optimal collocated positions of secondary source with two microphones are studied and the separate of transfer function method that reduce the influence of acoustic feedback are developed based on plane wave transmission theory of sound and concept of transfer function in a duct. After, In order to identify the variation of the signals and find out individual correlation coefficient, cross correlation function analysis between primary noise signal and reference input signal is processed.

本文根据管道声场的平面波传递理论，进行第二声源与两个感测麦克风之间的位置配置研究，配合数位讯号处理的技术，发展出转移函数分离法，以消除声场回授的影响，之后，再将使用和未使用转移函数分离法的讯号个别与主要噪音源讯号做交互相关函数的运算处理，辨识讯号之间的差异，找出个别的相关性系数。
