Filtration is the process of cleaning a liquid — or sometimes a gas — by passing it through a filter, so unwanted bits stay behind. It names the process, not the tool and not the liquid. You meet it in science class and in talk about drinking water.
FiltrationFiltration is the process of cleaning a liquid是把液體 — or sometimes a gas有時候是氣體 — 清潔的過程 by passing it through a filter通過過濾器, so讓 unwanted bits stay behind不需要的東西留下來. It它 names the process指的是這個過程的名字, not the tool不是工具, and也不是 not the liquid液體本身. You meet it你會遇到它 in science class and in talk about drinking water在科學課，還有談論飲用水的場合
Though actually, the tidy school word “cleaning” is a little neater than the lab. Chemists also say filtration when they are not making something nicer, only splitting a mixture: liquid through, solids left behind. Filtering coffee is, if you want to be exact, filtration, though almost nobody at breakfast says that.
Though actually不過其實, the tidy school word "cleaning" is a little neater than the lab學校教的那個乾淨字眼cleaning比實驗室裡的實際情況要整齊一點. Chemists also say filtration化學家也會說filtration when they are not making something nicer, only splitting a mixture在不是要讓東西變乾淨、只是要把混合物分開的時候: liquid through, solids left behind液體通過去，固體留下來. Filtering coffee is濾咖啡, if you want to be exact如果要講精確一點, filtration其實就是filtration, though almost nobody at breakfast says that只是早餐時間幾乎沒有人會這樣說
The word is a little formal and technical; the idea is ordinary: holes let the liquid through and hold the rest.
The word這個字 is a little formal and technical有點正式又技術性; the idea is ordinary但概念很平常: holes let the liquid through and hold the rest孔洞讓液體通過並擋住其餘的東西
English borrowed it from French filtration. Filter, , and filtration walk together: filter is the tool or the verb, filtration is the doing, is the liquid you get.
English borrowed it from French filtration英文是從法文filtration借來的. Filter, filtrate, and filtration walk togetherFilter、filtrate和filtration這三個字是一組的: filter is the tool or the verbfilter是工具或動詞, filtration is the doingfiltration是這個動作本身, filtrate is the liquid you getfiltrate則是你得到的那種液體
組成Borrowed from French filtration. In English it is filter + -ation (the process). Filter itself goes back, through French filtre and Latin filtrum, to felt — the thick cloth used to strain liquid.
