拐点频率 meaning in English
break frequency
Examples
- Based on the theory of mfl and a study on the signal characteristics ofac - mfl and ect : on one hand , it expouded the flaw identification model of “ slope ratio ” todetect the defects in panel , rob or pipeline ; on the other hand , the flaw - depth measurementmethod based on the characteristical frequency were used in ac - mfl . the application ofac - mfl was realized , and it showed the accordance of defect detection for these twotechniques
从其检测原理出发,在与上述涡流检测信号特点进行比较的基础上,一方面,利用“斜率比值”识别模型实现了对板材、管材、棒材等表面缺陷的检测;另一方面,利用交流信号的信息实现了基于拐点频率的深度测量方法在该技术中的应用。 - Based on that penetration depth of eddy current is theoretically different for different operationalfrequency , the flaw depth quantitive measurement method based on the characteristicalfrequency was expounded . to find the best testing model and position , it analysed and discussedthe factors which effected measurement . the mathematic relationship between the specialfrequencyand flaw depth was established to realize the accureate measurement of flaw depth . it primarily researched the technology of alternating current magnetic field leakage testing ( ac - mfl ) in our country
在利用频率扫描技术的基础上,提出了基于拐点频率的涡流检测缺陷深度测量方法,对影响测量的多种因素进行了分析和实验研究,得到了最佳的测试位置和测试方法,建立了拐点频率和缺陷深度的定量关系,为深度的测量提供了新的途径。
