液態氮遇上沸騰的機油：英語精讀講義

Hey guys,

大家好，

a couple weeks ago 片語搭配

幾週前

Castrol sent me some of their brand new Castrol Edge motor oil,

嘉實多給我寄了一些他們全新的 Castrol Edge 極護機油，

which is really good timing

這時機真的是太好了

because I just bought a car that needs an oil change.

因為我剛買了一輛需要換機油的車。

Now Castrol claims this is the strongest full synthetic oil 文法

現在嘉實多聲稱這是你能買到的最強全合成機油

money can buy for a whole number of reasons

其原因有很多

I'll tell you about later.

我稍後會詳細告訴你們。

But before I put this fluid titanium technology in my own vehicle,

但在把這種液鈦技術加進我自己的車裡之前，

I thought it would be exciting to run a few torture trials of my own. 慣用語

我覺得親自做幾次極限測試會很刺激。

Now the first experiment in the torture trials

那麼極限測試的第一個實驗

is called thermal shock. 用詞

叫做熱衝擊。

I brought back the mini metal foundry from a previous project 片語動詞

我拿出了之前項目中用過的迷你金屬熔爐

and we're going to use that to superheat the oil 用詞

我們要用它把機油超高溫加熱

to an extreme temperature.

到一個極端的溫度。

And then this little contraption uses a thermos to store liquid nitrogen.

然後這個小裝置會用一個保溫瓶來儲存液氮。

And when it's time,

等時候到了，

we'll pull the pin from a safe distance,

我們將在安全距離拔下插銷，

releasing the liquid nitrogen into the oil,

把液氮釋放進機油裡，

and seeing what kind of reaction takes place

看看會發生什麼樣的反應

when these two extremes collide head-on. 片語搭配

當這兩種極端物質正面碰撞時。

Now of course the disclaimer is

當然，免責聲明是

don't boil motor oil.

絕對不要去煮機油。

This is extremely dangerous.

這極其危險。

We're in a controlled environment 片語搭配

我們是在受控環境中進行的

and this is not something that should be duplicated.

這絕對不是應該被模仿的事情。

We're just doing it so you can see what happens

我們這麼做只是為了讓你們看看

if you did. 文法

如果你這麼做會發生什麼。

Okay, so update.

好了，最新進展。

We've got our thermos locked in the back position.

我們的保溫瓶已經鎖定在後方位置。

We've just filled it up with liquid nitrogen 片語動詞

我們剛把它裝滿了液氮

to the very top.

直到最滿。

And if we take the temperature,

如果我們測一下溫度，

you can see it's actually too low to measure. 文法

你可以看到溫度低得根本測不出來。

This is minus 321 degrees Fahrenheit.

這是華氏零下321度。

In contrast, 表達脈絡

相比之下，

if we look at the oil now,

如果我們現在看看機油，

we're about 425 degrees right now.

現在的溫度大約是425度。

I think it's time to drop the nitrogen.

我覺得是時候倒下液氮了。

All right, here we go guys.

好了，大家準備開始吧。

It's showtime.

好戲開場了。

Woah!

哇！

That was so much more than I was expecting. 文法

這比我預期的猛烈多了。

Boom!

砰！

Let's go check it out. 片語動詞

我們過去看看吧。

Oh, look look look look look.

噢，看啊看啊看啊看啊看啊。

You still see a little uh bubbling drops of liquid nitrogen

你還能看到一小滴一小滴冒著泡的液氮

floating on the top there.

漂浮在那上面。

How crazy is that? 語氣意圖

這有多瘋狂？

So the oil exploded out and we got a spray radius up to about

機油爆炸飛濺了出來，我們的噴射半徑大約

almost like 20 ft.

將近20英尺。

It was a good idea to be way way back there.

剛才退得遠遠的真是個好主意。

Well, that little makeshift contraption worked out pretty well, 片語動詞

看來那個自製的小裝置效果還不錯，

didn't it? 語氣意圖

不是嗎？

So let's move on to torture trial number two. 片語動詞

那麼我們繼續進行二號極限測試。

This second torture trial is called terminated and it'll make sense in just a second. 片語搭配

第二個極限測試叫做「終結者」，馬上你就會明白為什麼了。

The idea is to use liquid nitrogen

我的想法是使用液氮

to see if we can get motor oil to freeze completely solid. 文法

看看能不能把機油徹底凍成固體。

And to help me do that,

為了幫我實現這個目標，

I've got this cake mold that I got off the internet.

我準備了這個從網上買的蛋糕模具。

This is designed for baking and is made of silicone 片語搭配

它是為烘焙設計的，矽膠材質，

and should be able to handle temperatures of about 300 degrees,

應該能承受300度左右的溫度，

which is what our oil is at right now.

正好是我們機油現在的溫度。

So let's fill our mold up with oil,

那我們就把模具倒滿機油，

gently add liquid nitrogen around the edges,

在邊緣小心地倒入液氮，

and see if we can get motor oil to freeze completely solid.

看看能不能讓機油徹底凍成固體。

Check that out.

快看這個。

That's awesome.

太酷了。

Oh, it's amazing.

哦，太神奇了。

It's making little crystals.

正在結出小冰晶。

I'm not sure if it's doing that through the whole thing 文法

我不確定是整體都在結晶

or if that's just on the surface.

還是僅僅在表面上而已。

It's definitely unique formations.

這絕對是相當獨特的結晶形態。

Well, that's enough time for me.

好了，對我來說時間差不多了。

Let's take this thing over to tray and smash it.

我們把這東西拿到托盤裡砸碎。

It's pretty solid.

它非常堅硬。

Question is, can we get them out?

問題是，我們能把它弄出來嗎？

It's like the rubber and the oil have become one.

感覺矽膠和機油已經合為一體了。

I cannot physically separate them right now.

我現在根本沒法把它們分開。

I wonder if we should just smash it in the tray. 語氣意圖

我想或許應該直接在托盤裡砸碎它。

That might be the best bet. 慣用語

這可能是最好的辦法。

Here we go.

來吧。

That is insane.

這太瘋狂了。

You're looking at frozen motor oil.

你們看到的是凍住的機油。

That is nuts.

簡直瘋了。

Look at that guys.

看看這個夥計們。

Our motor oil seems to have survived test number two,

我們的機油似乎挺過了二號測試，

which is more than I can say for the silicone mold. 慣用語

但這矽膠模具可就沒這麼走運了。

So let's get this over to trial number three,

所以我們開始三號測試吧，

the blend test.

攪拌測試。

Now I just went and bought a high speed blender

我剛去買了一台高速果汁機

because for this last torture trial,

因為在這最後一個極限測試中，

I want to see how our oil holds up 片語動詞

我想看看我們的機油如何承受

to the extreme mechanical turbulence

這種極端的機械湍流，

generated by metal moving at high speed.

即由金屬高速運動產生的湍流。

Now this thing's been running for well over 10 minutes. 片語搭配

現在這台機器已經運行了超過10分鐘。

The only real difference that I've noticed is

我唯一注意到的明顯變化是

the temperature has risen to over 150 degrees Fahrenheit.

溫度已經升到了150華氏度以上。

And that's because of all the heat being generated

這都是由於刀片高速旋轉

by the friction of the blades spinning around so fast.

產生的摩擦力帶來了熱量。

Okay, check this out.

好了，看這個。

It's been over 20 minutes now

現在已經過去20多分鐘了

and I think our blender is breaking down 片語動詞

我覺得我們的果汁機快壞了

because I can see some oil spilling out the back.

因為我看到有些機油從後面漏出來了。

Woah, that's hot.

哇，好燙。

That's hot.

好燙。

That's hot.

好燙。

Dang, it's almost 200 degrees.

天哪，差不多有200度了。

This oil has been through a lot, 慣用語

這機油經歷了這麼多，

which is really amazing

真的很令人驚嘆

because it looks almost exactly like 文法

因為它看起來幾乎和

it did when it first came out of container.

剛從罐子裡倒出來時一模一樣。

We have boiled it, 文法

我們把它煮沸過，

we have frozen it solid,

把它凍成過固體，

we have smashed it,

我們砸碎過它，

and we have blended it.

並且我們還攪拌過它。

And it seems to have passed all those tests

它似乎通過了所有這些測試

with flying colors. 慣用語

且表現極為出色。

So, as a final testament to my commitment and confidence 用詞

所以，作為我對於 Castrol Edge 機油

in Castrol Edge motor oil,

之投入與信心的最終證明，

I'm actually going to put this stuff in the engine of my car

我真的要把這東西加進我汽車的引擎裡

and drive it around the country

然後開著它環遊全國

just to see how it holds up after all that abuse.

看看它在經歷了這麼多摧殘之後表現如何。

Now here's the thing about cars. 表達脈絡

關於汽車有這樣一點。

If you want them to treat you well,

如果你想讓它們好好為你服務，

you need to pay very special attention 片語搭配

你需要非常特別地注意

to what you put in your engine.

你加進引擎裡的到底是什麼。

And here's why.

原因是這樣的。

Today's engines are smaller and even more powerful 文法

現在的引擎體積更小，甚至比以前

than they were before,

還要更加強勁，

which means they run hotter 表達脈絡

這意味著它們運轉時溫度更高

and have to handle extreme temperature shifts.

並且必須承受極端的溫度變化。

The metal parts in your engine move at jet speed,

引擎內的金屬部件以噴射機般的速度運動，

creating insane amounts of pressure.

產生了極大的壓力。

And the only thing keeping the whole system 文法

唯一能讓整個系統

from blowing apart is a thin layer of oil

免於崩潰的，就是一層薄薄的機油

that lubricates and cools the engine.

它負責潤滑並冷卻引擎。

And to help spread the word about it, 慣用語

為了幫助宣傳這一點，

they made a really cool video

他們製作了一支超酷的影片

they want me to tell you about

他們想讓我介紹給大家

featuring world-class drivers racing digital clones

裡面有世界頂級的賽車手與他們自己的

of themselves with the goal

數位化複製人競速，目標是

to try and beat their own best time. 文法

嘗試打破他們自己的最佳紀錄。

It's never too late to get better performance 文法

想讓你的愛車獲得更好的性能

from your car.

永遠都不會太晚。

So consider switching from conventional oil 文法

所以考慮一下把普通機油

to Castrol's full synthetic motor oil,

換成嘉實多的全合成機油

Castrol Edge.

Castrol Edge 吧。

Oh, and feel free to replace the oil 語氣意圖

噢，而且隨時可以放心替換掉

that's already in there because contrary 表達脈絡

裡面已經有的機油，因為與

to popular belief,

普遍的看法相反，

you can switch between conventional and synthetic oils

你可以在普通機油和合成機油之間切換

as often as you want 文法

想換多少次就可以換多少次

without harming your engine at all. 文法

完全不會對你的引擎造成絲毫損害。

Well, thanks so much for joining me

好了，非常感謝大家今天來陪我

for these extreme experiments today guys.

看這些極端的實驗。

And thanks to Castrol for supplying the oil.

也感謝嘉實多提供的機油。

And of course, it goes without saying 慣用語

當然，不言而喻的是

these experiments cannot be duplicated at home.
