翻译。热稳定性

Hot stability refers to the ability of a substance or material to maintain its stability and integrity when exposed to high temperatures. It is a measure of how well a substance can resist degradation, decomposition, or any adverse changes in its physical or chemical properties when subjected to elevated temperatures. High hot stability is desirable for materials used in applications where they are exposed to extreme heat, such as in engine components, industrial furnaces, or aerospace systems.
