The average length of time during which a substance, a portion of material, or an object is in a given location or condition, such as adsorption or suspension.
〈技〉（物质、材料、物体处于特定位置或状态的平均持续时间，诸如进行吸收、悬空等）逗留时间，滞留时间
the construction of drains has reduced the residence time of water in the soil
Example sentencesExamples
The residence time of the participating water molecules can vary significantly.
The less material there is to heat, the shorter the required residence time.
The residence time is the average time an element spends in the ocean before it is removed to the sediment.
The offset in these two curves reflects the lengthy residence time for bioclasts in this high wave energy coastal environment, and a component of sediment recycling from older barriers.
The actual increase would be much less, since the residence time of water vapor in the atmosphere is about nine days.
