摘 要:
研究了基于电容原理测定刨花含水率的方法。试验表明：在一定含水率范围内，刨花含水率与其电容值成一定函数关系，当5%≤MC〈25%时，含水率与电容值成指数关系；当25%≤MC〈150%时则成线性关系。同时，被测物的堆积面积、堆积厚度等对测量结果有一定影响，需加以修正。[著者文摘]

Abstract:
The measurement of chip moisture content （MC）, based on capacitance, was researched. The results from the experiments showed that with given conditions there would be some functional relations between the MC of the chips and the value of their capacitance that were exponential when 5%≤MC〈25% and were linear when 25%≤MC〈150% At these conditions the chip MC could be measured through its capacitance. Models also included chip length, width, and thickness as these had some effect on coefficients that were included as correction factors.[著者文摘]
