  The job principle of measuring the rate that leads electricity of the sense machine that this text sketches the cable whirlpool and spreads , Combine it to silicon alloy material quality analysis of aluminium and instance of measuring , Have analysed the form of silicon crystal in the alloy and distributed to influence 、 changed of rate that leads electricity, The silicon alloy material quality dependence of the signal and aluminium of the sense machine that and probed into the cable whirlpool and spread, The factor of signal of the sense machine that method and influence cable whirlpool measured to the aluminium silicon alloy material quality spread of the sense machine that the cable whirlpool spreads , Measuring design of the instrument, the manufacture and application。
   The practical instrument has already been designed and made : Work up transformor whether type spread sense machine whether at low frequency vibration machine urge and down circuit by electricity whirlpool difference, The ones that exported the standard sample were with testing the difference value signal of style , Through enlarging、rectification、A / D Dealt with by the one-chip computer after changing, sends out signals and starts the corresponding display of the rank number going bad the single slice of machines at the end 。
   0。934 of coefficient correlation r= while organizing in metallography with the sample of value that shows instrument, Interval + of error is 0。
