coil impedance meaning in Chinese

线圈阻抗

In the eddy - current testing , testing coil is the sensitive component connecting the specimen and the instrument , so it is called transducer . the information of the test specimen is reflected by the variation of the coil impedance ( or induced voltage )
在涡流检测中，检测线圈是用来连接测试仪器和被测试件的敏感元件，它是涡流检测中的传感器，被检试件的信息是通过线圈阻抗(或感应电压)的变化反映出来的。
Therefore , it is very meaningful for both the electromagnetic theory and practical applications to study the electromagnetic field caused by testing coil and analyze the dependence of the coil impedance on the parameters that affect the coil impedance
因此，研究通电检测线圈周围的电磁场，分析检测线圈的阻抗与哪些因素有关，有何种关系，从而为检测线圈的绕制提供理论指导和参考，这无论在理论上，还是实际应用上都有重要意义。
