运行漂移
Operational DriftOperational drift is the irreversible microstructural evolution in long-lived functional materials induced by sustained electrical, thermal, mechanical, or chemical loading, which progressively alters the operative structure and performance over time. / 运行漂移是指长期功能材料在持续电、热、机械或化学载荷作用下发生的不可逆微观结构演变，它随时间推移逐渐改变工作结构并影响性能。
