材料熱膨脹係數測定儀 TA Discovery TMA 450EM / Thermomechanical Analyzer
品置於一個可透過程式控制升溫、降溫或恆溫的加熱爐中，通入固定的環境氣體，並在樣品上施予力量，紀錄樣品在溫度或力量改變下的形狀變化。
The sample is placed in a heating furnace that can be programmed to increase, decrease, or maintain a constant temperature. A fixed ambient gas is introduced, and force is applied to the sample to record the shape change of the sample under temperature or force changes.
