【摘要】 用单向稳定热流法测定纯度为99.95％的石英玻璃的导热系数,其温度范围为50～500℃,准确度估计到5％,发现石英玻璃的导热系数随温度升高而有所增大。更多还原

【Abstract】 In this article,the thermal conductivity of quartz was measured hy stationary are way heat flow methad,the temperature range being 50℃ to 500℃. And the purity of the quartz sample was 99. 95%. The accllracy of the experiment is estimatall as 5%. The thermal conductivity is found to be increasing smoothly as the temperature of the quartz sample increases.更多还原
