1. 使丧失能力;使伤残
    If an injury or illness disables someone, it affects them so badly that it restricts the way that they can live their life.

    e.g. She did all this tendon damage and it really disabled her...
           她遭受这么严重的肌腱损伤，这实际上让她残废了。
    e.g. Although disabled by polio during the Second World War, Proctor was also a first-rate helmsman.
           二战期间尽管身患小儿麻痹症，普罗克特仍不失为一流的舵手。

2. （通常指暂时地）使无效，使不能正常运转
    If someone or something disables a system or mechanism, they stop it working, usually temporarily.

    e.g. ...if you need to disable a car alarm.
           如果你需要暂停汽车报警功能
