  1. And a kind of 16 - step automatic selective programmable amplifying circuit is designed in volume resistivity measuring circuit, so as to handle sampling little and broad signal. the control and disposal system with the core of microchip at89c55wd is analyzed on chapter 4. main function unit such as the interface circuit of lcd display and keyboard, the interface circuit of micro - printer, real time clock ds12c887, and hardware anti - jamming technique are discussed

    本文還設計了以at89c55wd單片機為核心的控制處理系統的外圍介面電路及其軟體，對主要功能部分進行了分析，主要包括：鍵盤液晶顯示介面及界面設計、微型印表機介面、實時日歷時鐘晶元ds12c887 、單片機與單片機及單片機與上位機的通信設計以及控制系統硬體抗干擾措施等。
  2. The circuit utilizes 1mhz current - mode pulse width modulation ( pwm ) control to allow small input and output capacitors and a small inductor, while reducing the circuit ’ s volume and minimizing the input supply ripple to 15mv

    該電路採用頻率為1mhz的電流反饋模式脈沖寬度調制模式，可使外部電路選用小的輸入、輸出電容以及小電感，減小了電路的體積，同時能將輸入電壓紋波減小到15mv 。
  3. The measurement of dielectric loss and volume resistivity is effective preventive tests to judge insulating oil isolation status of polluted and aging, and it ' s important method of ensuring the safe operation of transformer and oil - filled circuit breaker, etc. however, the measuring systems of insulating oil dielectric loss and volume resistivity used at present exist the shortcoming of low accuracy, weak repeatability, inconvenience, and its thermostatic control system ca n ' t meet the challenge

    絕緣油的介質損耗因數、體積電阻率測量，是判斷絕緣油的劣化與污染程度的有效預防性試驗，是保障變壓器、油斷路器等充油電力設備安全運行的重要手段。然而，目前所使用的絕緣油介質損耗因數、體積電阻率測試系統存在著測量精度低、測量結果重復性不好、控溫系統不能滿足控溫要求、操作不便等缺陷，針對這一現狀，本文對絕緣油介損及體積電阻率一體化測試系統進行了研究。
  4. 7. build - in feedback inhibition circuit and volume control. 8. red indicative light on the mic

    13 .具有一組有線話筒輸入介面，獨立音量調節
  5. Any noise characteristic of the preamp circuit is attenuated along with the signal, unlike circuits where the volume control is before the input

    與一些音量控制置於輸入端的電路不同，這個前級放大器的特徵噪聲能夠隨同信號一起衰減。
  6. A way of controlling the voice volume in a wide range with program - control amplifier, the hardware circuit and constructing method of software are given

    摘要採用程式控制放大器對音量進行寬?圍控制，提供了具體硬體電路並指出了軟體構成方法。
