天氣變熱想降溫，擦汗有用嗎？ (Should You Wipe Off Your Sweat?)
- Obviously, evaporation is also super condition-dependent: if it's hotter or windier or drier, then the power of evaporative cooling increases substantially, while if it's cooler or more humid then evaporation is less effective.
顯然，蒸發也非常依賴條件：如果天氣更熱、風更大或更乾燥，那麼蒸發冷卻的能力就會大大增加，而如果天氣更冷或更潮濕，那麼蒸發的效果就會較差。
- increases substantially, while if it's cooler or more humid then evaporation is less effective.
如果溫度較低或溼度較大，蒸發的效果就會大打折扣。
冷氣的殘酷諷刺！ (The Cruel Irony Of Air Conditioning)
- And we'll need to go even further, by redesigning our entire cities to include more green spaces with trees that can provide shade, encourage hot air to mix with cool air, and cool the air themselves through evaporation.
我們甚至應該做得更廣，重新規劃整個市容，種更多樹就能有更多的遮陰、混合不同溫度的空氣、並且透過蒸發降低空氣溫度。
- and cool the air themselves through evaporation.
感謝明尼蘇達大學！
為何我們總是在重複中學習？ (Why We Only Learn When We Repeat)
- Far less naively and far more generously, religions prefer to imagine that anything you tell someone in the morning will, by two in the afternoon, be well on the way to evaporation and will be pretty much gone by nightfall.
將內容倒進去後，它們幾乎就可以保存相當於人一生的時間。
- in the morning will, by two in the afternoon,
be well on the way to evaporation and will
至於信仰，則毫不天真與更大方地認為，人們早上說過的話，到了下午兩點就會開始慢慢忘記，
冷卻塔為什麼要設計成那樣？ (Why Are Cooling Towers Shaped Like That?)
- So as long as the ambient air isn't already saturated, 100% relative humidity, you can actually cool water below the dry bulb temperature using evaporation.
是以，只要環境空氣不是已經飽和（相對溼度為 100%），就可以利用蒸發將水冷卻到乾球溫度以下。
- And the lower the humidity of the air, the more evaporation can take place, so the bigger the difference in wet and dry bulb temperatures.
空氣溼度越低，蒸發量就越大，乾溼球溫差也就越大。
