First it produces the pulse signal by the multivibratorwhich is consisted of 555 timer and send in the detecting coil to form the alternating magnetic field, then it asopts UGN3503 linear half-effect as prode to the magnetic field change into the voltage signal change,after enlargement electric circuit and peak value examination electric circuit,the signal be treated to send into ADC0809 modulus converter change moduluses, then the digital signal after the modulus converter is changed is sent into AT89C51one-chip computers afterwards, after the digital filter, AT89C51one-chip computers afterwards compares the data to the reference voltage and judges whether to have detected the metal and alarm.

这个系统是以AT89C51单片机为核心，首先由555定时器构成多谐振荡器产生脉冲信号送入探测线圈以形成交变磁场，然后经过线性霍尔器件UGN3503将磁场变化转换为电压信号的变化，经过放大电路和峰值检测电路，经数模转换之后输入到单片机中，由单片机对数据进行软件滤波之后，与基准值比较之后，判断是否存在金属和报警显示。

After adjusted the voltage of analog signal, corresponding channel selection was implemented with relay matrix. The analog signal is transmitted as the input of tested instrument.

输出的模拟信号经电压调整后通过继电器矩阵完成相应的通道选择，作为被测试设备的输入信号。

It is split into two parts. One is a user-space series of C++ classes which implement a reference application called DAQSystem which is designed to acquire analog input voltage data and display it on the screen.

它被分割为两个部分，一部分是用户空间的C++类系列，实现了一个称为DAQSystem 的参考应用程序，用于接收模拟输入的电压数据并在屏幕上显视。

Detailed derivation of input current and double-line frequency output voltage ripple are presented.

这种电路控制复杂，输出电压比输入高，难以实现输入输出的电气隔离。

The kernel of thecontrol system hardware is an industrial control PC, voltage AD, current AD anddigital input/output plates are equipped to respective signals collected, which collectand control main parameters of transmission assembly. For the convenience of wiringand signal modulating, a harness plate adapting to collection plate is configured.

测控系统的硬件以一台工业控制PC机为核心并根据采集信号的性质配置了电压-数字量转换板、电流-数字量转换板及数字量输入/输出板，对变速箱总成的主要参数进行采集和输入转速等的控制；为方便接线和信号调理，配备了与采集板对应的接线和调理接口板以及接线盒。

The instrument change speed of revolution to impulse signal by photoelectric transducer and as input signal of 8031 uniwafer-computer, then count input signal of revolution speed impulse through Time/Counter of 8031, thus revolution speed was measured.

此电压测量装置利用光电式传感器把转速信号转换为脉冲信号，作为输入信号通过8031单片机的定时器/计数器对输入的转速脉冲信号进行计数，来测量转速。

Turn it back on and set the box cover at the right, and then set the pumb output tubes and machine into the tubing connected, and then on the machine: the pumb work grow up immediately, and mold hold its output tube is also apparent from inside the pent up spilling in output occurred at both the reliability and vibration grow up; then view the instructions in the oil pressure table has been rising "" 0 to "" 5, at the same time, pressure relay (and by keeping the switchboard AC closing in — from its contact outgoing voltage) order lubrication solenoid valve work of fuel, oil pressure decreased and quickly rose to require lubrication with pressure-a solenoid valve, so self-repeating.

重陈不兵其拧不松并不兵盒盖上好，再不兵油泵输入惯与机械的不退油惯接开，然后试机：油泵处事的声音当即变不小了，且用手捏握其输入惯也暗显感触边面流油的鼓胀度和震不不静度均变不小了；再不雅油压外洋的辅导已由&0&逐步上降到了&5&，与此同时，不张力继电器不不静息（并开功使配电柜内互换隔绝器呼分——由其触不面传不入电压）令润滑电磁阀处事——放油，油压回降后又迅不缓上降至规矩不张力后再令润滑电磁阀放油，如此轮回来往。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
