摘要
基于似稳场探测原料中金属物的原理,导出了描述差动检测方式的数学表达式,并对金属信号的产生及其提取作了详细地分析。文中论述了在实际应用中相位设置与金属特性以及检测灵敏度之间的相互关系。
Applying the theory of quasi-stationary ellectromagnetic field detecting metal in bulk materials,this paper reaches an equation that describes differential detection and analyses the generation and extraction of the metal signal in detail. The paper also discusses the relationship of metal character and detection sensitivity and phase setting-up in application.
