threshold
含义: The level or point at which something begins to take effect, change, or become apparent, or literally, the strip of wood or stone forming the bottom of a doorway.
Threshold is one of the most productive metaphorical words in English. In science, it refers to the minimum intensity of a stimulus needed to produce a response — the pain threshold, the hearing threshold. In economics, it denotes the income level at which a tax rate changes. In computing, a threshold value triggers an action when exceeded. The literal sense of a doorway entrance persists in ceremonial contexts, such as carrying a bride across the threshold.
