For example, you can define a threshold alert to be triggered if your Buffer Pool Hit ratio drops to below 60% for a warning level or 55% for a problem level.
例如，您可以定义当Buffer Pool Hit ratio下降到低于60%时触发一个警告级阈值提醒，或者低于55%时触发一个问题级阈值提醒。
When the voltage in the capacitor reached a certain level, it triggered the transistor; the transistor turned on, and the wipers wiped once.
当电容器电压达到一定程度，它便会激活晶体管；晶体管打开，雨刷运转一次。
Japan itself had a Level 4 accident in 1999, when three workers preparing fuel for a reactor at a Japan Nuclear Fuel Conversion plant triggered a nuclear chain reaction, called a criticality.
日本在1999年就曾发生过一次4级核事故（又称“东海村核事故”——译注），当时在日本核燃料转换公司（Japan Nuclear Fuel Conversion）的一个燃料厂内，三名正在为反应堆准备燃料的工人引发了一次链式核反应，使反应堆达到临界状态。
