TC—3000型热系数测定仪,采用激光闪光法测量固体试样的三个热系数—热扩散系数、比热和导热系数。该仪器带有计算机,用于数据处理、绘图及制表。因此,与其它仪器比较,具有速度快、准确度高等优点。借助于该仪器,我们得到了大量的金属和非金属材料的有关热物性数据,为衡量材料能否适应热过程工作需要提供了重要依据;我们还对物质比热与物质结构关系进行了研究,揭示了不同物质的比热随温度演变的内在关系。从而得出,对于未知相变温度的物质,可通过测量其比热值,并由计算机绘出比热—温度的关系线,便可大致确定该物质的相变温度区间。这对于研究新材质起着重要的作用,也为测定相变温度增加了一种新手段。 TC-3000 Thermal Coefficient Tester, using the laser flash method to measure three thermal coefficients of solid samples - thermal diffusivity, specific heat and thermal conductivity. The instrument comes with a computer for data processing, drawing and tabulation. Therefore, compared with other instruments, with high speed, high accuracy and so on. With the help of this instrument, we have obtained a great deal of thermophysical data about metal and nonmetallic materials, which provide an important basis for measuring the suitability of materials for the thermal process. We also study the relationship between material specific heat and material structure, Reveals the intrinsic relationship between the specific heats of different materials with the evolution of temperature. Thus, for unknown phase transition temperature of the material, by measuring its specific heat value, and the computer to draw the relationship between specific heat - temperature, you can roughly determine the phase transition temperature of the material. This plays an important role in the research of new materials and also adds a new measure for determining the phase transition temperature.
