摘要
用瞬态热流法测定玉米的热导率。玉米的含水率为9．25％～17.14％，温度为-32.3～17.2℃。结果表明：用0．40A电流测得的热导率与用0．44和0．36A测得的热导率没有明显差别；在加热时间分别为8，9和10min测得的热导率之间也没有明显差别。热导率与含水率和温度呈现良好的线性关系。
The thermal conductivity of corn is measured by the transient heat flow method.Before measurement, the moisture content of the corn is in the range of 9. 25% to 17. 14%,and its temperature is of -32. 3℃ to 17. 2℃. The results show that the thermal conductivity is no obvious difference when current is 0. 40 A compared with those tested under 0. 44 A and 0. 36 A. The thermal conductivity is also no obvious difference when the heating periods are 8, 9 and 10 min, respectively. It has been found that the thermal conductivity is a linear function of the mositure content and temperature.
