采用瞬变平面热源法,测定了常压、温度233.15～273.15K下四氢呋喃水合物的导热系数,其范围在0.45～0.54W·m-1·K-1之间。实验结果表明,常压下四氢呋喃水合物的导热系数呈现随温度升高而增大的趋势,与玻璃体的变化特性相同。常压下四氢呋喃水合物的导热系数与高压下的数值相比差别很小,但常压下测得的四氢呋喃水合物导热系数的玻璃体变化特性比高压下明显。 The thermal conductivity of tetrahydrofuran hydrate at atmospheric pressure and temperature from 233.15 to 273.15 K was measured by the transient planar heat source method. The thermal conductivity was in the range of 0.45-0.54 W · m-1 · K-1. The experimental results show that the thermal conductivity of tetrahydrofuran hydrate at normal pressure shows a tendency of increasing with temperature, which is the same as that of vitreous. The thermal conductivity of tetrahydrofuran hydrate at atmospheric pressure is very small compared with the value under high pressure, but the glass transition characteristic of the thermal conductivity of tetrahydrofuran hydrate measured at atmospheric pressure is obviously higher than that under high pressure.
