erratic current 中文意思是什麼
erratic current
解釋
不穩定的電流-
According to the electromagnetic induction theory, abrupt variation of current in the transmitter loop will induce magnetic field around it, which is called the first field. in the transmission of the first field, when it meets good conductor target, induce current will be created, which is called erratic current of second current. because the second current changes with time, so it will create new magnetic field, which is called
對于接收部分,由於瞬變信號具有早期信號幅度大、衰減快,而中晚期信號幅度小、衰減慢的大動態范圍的特點,必須設計適應這種大動態范圍信號的採集電路;為了適應野外工作,系統主控部分採用具有功耗低、高速處理的dsp ,通過高速通用串列介面usb與上位機通訊,實現對整個探測系統的控制。
