摘要：接地技術是抑制噪聲和防止干擾的重要手段之一。本文就線路設計中地線干擾的產(chǎn)生和測量、地線干擾的抑制和對常見的接地方式做了論述，并對實際電路中地線的設計和接地時應考慮的問題做了分析。 敘詞：干擾產(chǎn)生 干擾抑制 測量 接地方式 Abstract：The grounding is an important means to suppress noise and to prevent interference. Ground interference, circuit design, generation and measurement, ground interference suppression and discusses common ground and circuit ground and ground should be considered to do the analysis.Key words: Interference generated, Interference suppression, Measuring, Grounding method Keyword：Interference generated, Interference suppression, Measuring, Grounding method
