应用差示扫描量热仪测量碳纤维毡的比热采用兰宝石(氧化铝)作为标准参考物,其测量精确度为0.3％。与绝热量热法的精确度相近,差示扫描量热法的优点是只需用很少的样品就可以快速、方便地测量固体和非挥发性液体的热焓和比热,通过计算机直接打印出数 The specific heat of carbon fiber mats was measured using differential scanning calorimetry using sapphire (alumina) as a standard reference with a measurement accuracy of 0.3%. Similar to the adiabatic calorimetry accuracy, the advantage of differential scanning calorimetry is the rapid and easy measurement of the enthalpy and the specific heat of solid and non-volatile liquids with very few samples and direct printing by computer Number out
