Good morning, Hana. Welcome to the undergraduate chemistry laboratory for the first time.

早安，Hana。歡迎第一次來到大學部化學實驗室。

Good morning, Professor. I have to admit, I'm both thrilled and slightly intimidated by all this equipment.

教授早安。我必須承認，看到這些設備，我既感到興奮又有些畏縮。

That's a perfectly natural reaction. Were you to neglect the inherent risks here, I'd be more concerned.

那是完全正常的反應。如果你忽視了這裡固有的風險，我反而會更擔心。

Fair point. So, where do we begin today?

有道理。那麼，我們今天從哪裡開始呢？

First and foremost, let me outline the safety protocols that govern everything we do here.

首先，讓我概述一下規範我們這裡所有行為的安全協定。

I read the handbook online, but I suppose hands-on guidance is indispensable.

我已經在網路上讀過手冊了，但我認為實際的指導是不可或缺的。

Precisely. Under no circumstances should you handle chemicals without wearing protective goggles and gloves.

正是如此。在任何情況下，你都不應在未佩戴防護護目鏡和手套的情況下處理化學品。

Got it. What about the fume hood? I've seen those in YouTube videos but never used one.

明白了。那排煙櫃呢？我在 YouTube 影片上看過那些，但從未使用過。

The fume hood extracts toxic vapours so that you aren't exposed to harmful substances.

排煙櫃會抽出有毒蒸氣，好讓你不會暴露在有害物質中。

#10

That makes sense. Now, what experiment are we conducting today, if I may ask?

那很有道理。那麼，如果可以請問的話，我們今天要進行什麼實驗呢？

#11

We'll be testing a hypothesis about the reaction rate between zinc and hydrochloric acid.

我們將測試一個關於鋅與鹽酸之間反應速率的假設。

#12

Interesting! I actually debated reaction kinetics with my chemistry teacher last week.

太有趣了！我上週其實才跟我的化學老師辯論過反應動力學。

#13

Excellent. Now, set up the equipment precisely as indicated in the procedure sheet on your bench.

太好了。現在，請精確地按照你實驗桌上程序單中的指示來組裝設備。

#14

Let me check — a conical flask, a measuring cylinder, a stopwatch, and a thermometer. Is that everything?

讓我檢查一下——一個錐形瓶、一個量筒、一個秒錶和一支溫度計。就這些了嗎？

#15

Indeed. Should you notice any irregularities during the experiment, record them immediately in your logbook.

的確。如果在實驗過程中發現任何異常情況，請立即記錄在你的實驗日誌中。

#16

Will do. I'll also take photos for my lab report, provided that's permitted.

我會照做的。我也會為我的實驗報告拍照，前提是那是被允許的。

#17

By all means. Now, once you've obtained your result, compare it with the theoretical prediction.

當然可以。現在，一旦你得到了結果，就將其與理論預測進行比較。

#18

What if the result deviates significantly from what we anticipated?

如果結果與我們預期的有顯著偏差該怎麼辦？

#19

Then we investigate the discrepancy. Not only does an unexpected result teach us something, but it also refines our hypothesis.

那麼我們就調查其中的差異。出乎意料的結果不僅能讓我們學到東西，還能完善我們的假設。

#20

That's reassuring. I suppose science is as much about embracing failure as celebrating success.

那真令人寬慰。我想科學與其說是慶祝成功，不如說是擁抱失敗。

#21

Couldn't have put it better myself. Now, let's get started, shall we?

我也沒辦法說得比這更好了。現在，我們開始吧，好嗎？

By all means

idiom

Of course; used to give permission or encouragement.

當然可以、儘管（做某事）

解釋： 一種禮貌且熱情的許可表達方式，表示完全同意對方的請求。

範例： If you want to take a look at the data, by all means, go ahead.

Couldn't have put it better myself

idiom

Used to express complete agreement with what someone has just said.

我完全同意、說得再好不過了

解釋： 表示對方的措辭非常精確，自己無法表達得更完美。

範例： You think we need more funding? I couldn't have put it better myself.

fume hood

technical term

A ventilated enclosure in a laboratory, in which harmful volatile chemicals can be used or kept to prevent the inhalation of toxic vapors.

排煙櫃 / 通風櫥

解釋： 「Hood」在日常生活中通常指外套的「兜帽」或汽車的「引擎蓋」。在實驗室語境中，它指的是一種箱型通風設備，利用抽風系統將實驗產生的有害氣體排出。

範例： Always perform volatile reactions inside the fume hood to ensure safety.

bench

technical term

A long, sturdy work table used for scientific research, experiments, or manual work in a laboratory.

實驗桌 / 工作台

解釋： 「Bench」在日常生活中多指公園或公共場所的「長凳」。但在科學領域，它指的是實驗室裡專門用來放置儀器和進行操作的重型工作台。從事第一線研究的科學家常被稱為「bench scientist」。

範例： Please clear your bench of all unnecessary items before starting the titration.

conical flask

technical term

A piece of laboratory glassware with a flat bottom, a conical body, and a cylindrical neck, also known as an Erlenmeyer flask.

錐形瓶 / 三角瓶

解釋： 「Flask」在日常生活中常指「保溫瓶」或「隨身酒瓶」。在化學實驗室中，它特指各類玻璃瓶，而「conical」則描述其特有的錐形形狀，以便於搖晃液體而不易濺出。

範例： Swirl the conical flask gently while adding the acid.

measuring cylinder

technical term

A common piece of laboratory equipment used to measure the volume of a liquid, characterized by its narrow, cylindrical shape and marked graduations.

reaction kinetics

technical term

The branch of physical chemistry that is concerned with understanding the rates of chemical reactions.
