In the science sense, an electrolyte is a liquid (or a melted substance) that lets electricity pass through it. The current can travel because the liquid has charged particles that can move. Salt water is a simple example; pure water is a poor one.

In the science sense在科學上的意思裡 an electrolyte電解質 is a liquid (or a melted substance)是一種液體（或熔化的物質） that lets electricity pass through it能讓電流通過 The current電流 can travel能通過 because the liquid has charged particles that can move是因為液體裡有可以移動的帶電粒子 Salt water鹽水 is a simple example是一個簡單的例子 pure water純水 is a poor one就是一個不好的例子

Though actually, everyday English has stretched the word. On sports bottles and in clinics, “electrolytes” often means the body salts themselves — sodium, potassium, and the rest — that you lose in sweat, not the liquid as a whole.

Though actually不過其實 everyday English has stretched the word日常英文把這個詞的用法拉寬了 On sports bottles and in clinics在運動飲料的瓶子上和診所裡 “electrolytes” often means the body salts themselves「electrolytes」常常是指身體裡的鹽分本身 sodium, potassium, and the rest鈉、鉀等等 that you lose in sweat也就是你流汗流掉的那些 not the liquid as a whole而不是指整體的液體

Scientists still use the older, stricter sense Faraday named. It is a school-science and medical word; drinks ads use it more loosely than a chemistry teacher would.

Scientists科學家 still use the older, stricter sense Faraday named還是用法拉第當初定的那個比較嚴格的舊定義 It is a school-science and medical word這是一個學校科學課和醫學上的詞 drinks ads use it more loosely than a chemistry teacher would飲料廣告用得比化學老師還要鬆散
