3 Terms and Definitions
GB/T 13966 and established in the following terms and definitions apply to this section.
3.1
Under program control the temperature, measuring the physical properties of a class of technology and the relationship between the temperature of the material.
3.2
Under program control temperature, temperature measurement technology quality and substance of the relationship.
3.3
The TG curve obtained by thermogravimetric method for temperature or time of the first order derivative method, that the rate of change in weight as a function of temperature or time
It is continuously recorded.
3.4
Under program control the temperature, the temperature difference between measurement technology and temperature dependence of substance and reference material.
3.5
Under program control temperature measurement input into the substance and reference material difference between the temperature dependence of the energy technologies. Press measurement methods can be divided into. Power
Rate compensation differential scanning calorimetry (Power-Compensationdifferentialscanning) and heat type differential scanning calorimetry (Heat- fluxdifferentialscanningcalorimetry).
3.6
Under program control the temperature of a sample simultaneously using two or more thermal analysis techniques. For example, simultaneous thermogravimetric measurements and differential thermal analysis. Using abbreviations, it should be between the two plus one short-term, such as TG-DTA.
3.7
Under program control the temperature of a sample simultaneously using two or more techniques for analysis, the use of the instrument via an interface phase […]
