1. 退化：该系统是针对高温组件测试设计,可以用来测试陶瓷膜,电极,密封,催化剂以及完整的固体氧化物燃料电池膜电极及短电堆(short stacks). 该系统是分析耐用性(durability)及退化(degradation)等材料及组件特性的理想平台

2. 降级：在这里,损耗诱导降级与拉曼诱导降级(degradation)之间达到了一种平衡. 图中显示,CNR曲线在感爱好的距离上都比较平坦,可以预期对业务的影响是比较小的. 在那些需要额外盈余(margin)的地方,有一种非常简单的方法来减少拉曼效应所带来的影响.

3. 降解：为了确保该循环的顺利运行,降解(degradation)和合成(synthesis)学状态之中. 在这个均衡稳定的系统(homeostatic system)中,大量的有机化合物被的主体部分. 为了确保该循环的顺利运行,降解(degradation)和合成(synthesis)

4. 劣化：美国认为,伴随着核电站的高服役期,安全壳的腐蚀(corrosion)和劣化(degradation)现象的发生率呈增加趋势. 与钢制和混凝土制安全壳有关的老化研究计划主要有: (1)核电厂老化研究(NPAR)计划; (2)构筑物老化研究(SAG)计划;

1. 丢脸;（尤指）落泊,堕落

    e.g. There are serious problems of land degradation in some arid zones.
           在一些干旱地带存在严重的土地退化问题。
    e.g. ...the accelerating degradation of our planet''s natural environment.
           地球上自然环境的加速退化

4. 降解
    In science, the degradation of a substance is the process of its breaking down into its separate parts or elements.

    e.g. ...the degradation of salicylic acid in plants.
           植物中水杨酸的降解
