一、热分析的意义在等速升温的系统中,物质随着温度的变化而发生各种物理和化学效应,同时会产生各种能量的变化,根据这些能量的大小就能对该物质进行定性和定量分析。这种方法叫做热分析(Thermal Analysis)。二、热分析仪的组成根据上述定义,一台热分析仪就必须具备如下几个条件:(1)要有一个能等速升温的并且具有一定长度等温区的加热炉;(2)要有一个能放置试样的支架并且能探索试样微小能量变化的探头;(3)能把探头所得的能量转换成电能的换能器;(4)能把微小电能放大的放
First, the significance of thermal analysis In the system of constant temperature heating, the material with the temperature changes and the occurrence of a variety of physical and chemical effects, and will produce a variety of energy changes, according to the size of these energy can be qualitative material And quantitative analysis. This method is called Thermal Analysis. Second, the composition of the thermal analyzer According to the above definition, a thermal analyzer must have the following conditions: (1) to have a constant temperature isothermal and have a certain length isothermal zone furnace; (2) to have A probe that can hold a sample holder and can detect small changes in the energy of the sample; (3) a transducer that converts the energy obtained by the probe into electrical energy; (4)
