一、前言文中介绍一台中国科学院地质研究所自制的热重分析仪,及其操作方法。这台仪器能够完全自动的记录而划出热重曲线。热重分析在矿物和化学制品的鉴定上有广泛的用途,凡是含水和含挥发性成分的物质,受热分解脱离物质而失重,由于它们化学成分的不同及其结晶构造上的差异,失重会在不同温度的阶段上出现,在连续自动记录的曲线上,可以真实地划出物质不同的特性 I. Preface The text introduces a thermogravimetric analyzer made by Institute of Geology, Chinese Academy of Sciences and its operation method. This instrument can be fully automatic record and draw the thermogravimetric curve. Thermogravimetric analysis has a wide range of uses in the identification of minerals and chemicals. Anything that contains water and contains volatile components that lose weight due to thermal dissociation and dissociation of substances, due to their different chemical compositions and differences in their crystalline structure, Appear on the stage of different temperature, on the curve that records continuously continuously, can draw out the material different characteristic truly
