【摘要】 建立了非补偿微热量热法测定圆筒体炸药试样导热系数的实验装置和方法，测定了聚四氟乙烯、有机玻璃、高密聚乙烯三种标准物质及ＪＨ－９１０５、ＪＯＢ－９００３、ＪＯ－９１５９、ＪＯ－９１８５、ＪＯＢ－９００６、ＪＢ－９００１等六种塑料粘结炸药在２９８．２Ｋ下的导热系数，对非补偿测定法与补偿测定法进行了对比。结果表明：非补偿法与补偿法测试准确度相当，但测试时间大大缩短更多还原

【Abstract】 A device and an experimental method are developed to determine the thermal conductivity of explosive specimens with hollow cylindrical shapes by a noncompensation microcalorimetry method.The λ values of three standards (PTFE,PMMA,high density polyethylene) and six plastic bonded explosives (JOB 9003,JO 9159,JO 9185,JH 9105,JOB 9006 and JB 9001) were determined at 298.2K.Comparisons between the noncompensation method and the compensation method are also presented.The results show that both methods have the same accuracy for determining λ ,but the time consumption of determinations by the former is much lower than that by the latter.更多还原
