dew point

常見例句

The NWS Web site features a handy on-line calculator for determining the heat index based on a combination of either temperature and relative humidity or temperature and dew point.
國家氣象局（NWS）網(wǎng)站公布了一個方便的在線計算器便于大家基于溫度和相對濕度或溫度和露點的結合來計算炎熱指數(shù)。
Like all clouds, it forms when the air reaches its dew point, which is the temperature to which an air mass must be cooled for the water vapor in it to condense into liquid droplets.
和其他云一樣，它是當空氣達到凝結點，即空氣團的溫度冷卻到使其中的水蒸氣凝結成液態(tài)水滴的溫度時形成的。
Due to compression process influence the air dew point of compressed air in the pipeline, run it will gradually decrease temperature, so the compressed air system always have liquid water.
由于壓縮過程影響空氣的露點，壓縮空氣在管線中運行時溫度會逐漸降低，所以壓縮空氣系統(tǒng)中總是有液體水存在。
