3 terms and definitions
GB/T 6425-2008 The definitions and definitions of the following terms and definitions apply to this document. For ease of use, some of the following are repeated
Terms and definitions.
3.1
Thermogravimetric analysis
A technique for measuring the relationship between sample mass (or mass fraction) and temperature (or time) in a controlled temperature and a certain atmosphere.
[GB/T 6425-2008, definition 3.2.1]
3.2
Thermogra curve thermogravimetriccurve
TG curve TGcurve
The curve of the data measured by thermogravimetry in mass (or mass fraction) in the form of temperature or time. Curve ordinate for quality
The amount of m (or mass fraction), upward to increase the quality, down to show the quality reduction; abscissa for the temperature T or time t, from left to right that temperature
Increased or increased time.
[GB/T 6425-2008, definition 3.2.5]
3.3
Quotient thermogravimetric curve
DTG curve DTGcurve
The data measured by the thermal balance are plotted against the relationship between the mass change rate and the temperature (scanning type) or time (constant temperature type). When the sample quality
When the DTG curve is increased, the peak decreases when the mass decreases.
[GB/T 6425-2008, definition 3.2.6]
