天氣變熱想降溫，擦汗有用嗎？ (Should You Wipe Off Your Sweat?)
- But a human body can't necessarily evaporate a liter of water every hour: a square meter, under room temperature conditions, will only evaporate about a third of a liter per hour, and the surface area of a human is only between 1 and 2 square meters.
但人體不一定每小時蒸發一公升水：一平方公尺，在室溫條件下，每小時只會蒸發約三分之一公升，而人體的表面積僅在 1 至 2 之間平方公尺。
- temperature conditions, will only evaporate about a third of a liter per hour, and the surface area
溫度條件下，每小時只能蒸發約三分之一升，而表面積

- Their surface area is up close to some of the smallest states on Earth,
它們的表面面積，接近地球上一些比較小的國家，
- Their surface area is up close to some of the smallest states on Earth,
它們的表面面積，接近地球上一些比較小的國家，
二維世界的週期表！ (The Periodic Table in a 2D World)
- First, while in 3D the electromagnetic force that attracts electrons to the nucleus is a one over r squared law, since it depends on the surface area of a sphere, in 2D, a sphere is just a circle whose surface area is its circumference, so the electromagnetic force is a one over r law.
首先，在三維空間中，將電子吸引到原子核上的電磁力是一個大於 r 平方的定律，因為它取決於球體的表面積；而在二維空間中，球體只是一個圓，其表面積就是圓周長，所以電磁力是一個大於 r 的定律。
- First, while in 3D the electromagnetic force that attracts electrons to the nucleus is a 1 over r squared law, since it depends on the surface area of a sphere, in 2D a sphere is just a circle whose "surface area" is its circumference, so the electromagnetic force is a 1 over r law;
其次，由於二維空間中可移動的維數較少，電子繞軌道運行的方式也較少，這意味著每個能級的軌道較少。
厭食症是致死率最高的精神疾病！ (Anoreixa is the most lethal mental illness)
- Based on 1,648 female brain scans, researchers found decreases in cortical thickness, subcortical volumes and cortical surface area, the brain essentially shrinks down.
根據對 1648 名女性的大腦掃描結果，研究人員發現大腦皮層厚度、皮層下體積和皮層表面積都有所下降，大腦基本上縮小了。
- Based on 1,648 female brain scans, researchers found decreases in cortical thickness, subcortical volumes, and cortical surface area.
我很擔心你。
MySQL EXPLAIN 讓你查詢效能神救援！ (Use MySQL EXPLAIN for Query Optimization)
- Here we can see how the CO table is a materialized subquery created by first doing a table scan on the country table, then applying a filter for the continent, then sorting based on the surface area, and then limiting the result to 10 rows.
在這裡，我們可以看到 CO 表是一個具體化的子查詢，它首先對國家表進行表掃描，然後應用大洲過濾器，再根據表面積排序，最後將結果限制為 10 行。
- Here, we can see how the co table is a materialized subquery created by first doing a table scan on the country table, then applying a filter for the continent, then sorting based on the surface area,
在這裡，預計 17 行的估計成本約為 4 行。
冷卻塔為什麼要設計成那樣？ (Why Are Cooling Towers Shaped Like That?)
- I'm just using a dehumidifier pad, but in an actual cooling tower, the fill is usually a layer of plastic carefully designed to maximize the surface area of the water in the system.
我只是在使用除溼墊，但在實際的冷卻塔中，填充物通常是一層精心設計的塑膠，以最大限度地增加系統中水的表面積。
- The goal is to expose as much surface area of the hot water as possible to the air flowing through the tower.
這樣做的目的是讓儘可能多的熱水表面積暴露在流經塔內的空氣中。
把空氣變成飲用水！臺灣竟然也做得到？方法大公開！ (Transforming Air Into Pure Drinking Water Is Finally Possible, Here's How)
- A single gram of a MOF can have the surface area of a football field,
這種結構使它們像海綿一樣成多孔狀，
- the surface area of a football field.
具有一個足球場的表面積。
樹木比我們想像的還要瘋狂！🌳🤯 (Trees Are Even More Crazy Than We Thought)
- It is made from hundreds of millions of factory cells and optimised to have as much surface area and be as thin as possible to harvest sunlight.
但大氣中只有大約 0.04% 是 CO2，也就是每百萬個空氣分子中有 425 個 CO2 分子。
- It's made from hundreds of millions of factory cells and optimized to have as much surface area and be as thin as possible to harvest sunlight while your skin is Hundreds of cells thick, a leaf can be just 10 cells top to bottom.
它由數億個工廠細胞組成，並經過優化，表面積盡可能大且盡可能薄，以便收集陽光，而您的皮膚有數百層細胞那麼厚，一片葉子從頂到底可能只有 10 層細胞。
