OK, so we are about to demonstrate

好了，我們現在要演示的是

Dragon's Breath ammo, the ultimate in muzzle flash, and we got

龍的呼吸彈藥，在槍口閃光的終極，我們得到了。

the most manly person we know, John to do it, John can you hear us? - yeah

我們所知道的最有男子氣概的人，約翰來做，約翰你能聽到我們嗎？- 聽到了

-Are you ready? - Ready.

-你準備好了嗎？- 你準備好了嗎？

3..2..1.. [bang] [laugh]

3..2..1..[砰] [笑]

[music]

[音樂]

What if you catch yourself on fire?

如果你自己著火了怎麼辦？

[bang] [laughs]

[砰] [笑]

Fantastic!

太棒了！

3.. 2.. 1.. Fire

3.. 2..1..1...

- Holy Crap. - That's amazing.

- 我的天啊- 太神奇了

Aah, that's the shot right there.

啊，這就是那一槍。

Look at this. - Ow man.

看看這個。- 噢，夥計。

3..2..1..

3..2..1..

Alright, man play with fire time is over.

好了，夥計玩火時間結束了。

It's time for you to get Smarter Every Day. So I've obtained a document

是時候讓你每天更聰明瞭。所以我獲得了一份文件

made by the US Department of Energy back in 1984 reviewing Zirconium

美國能源部早在1984年就審查了鋯

Zircaloy Pyrophoricity. This is important because this is what's used in

Zircaloy熱釋性。這一點很重要，因為這是用於

Dragon's Breath ammunition. This is a little different than normal tracer ammunition which uses

龍息彈。這與普通的曳光彈有一點不同，它使用的是

magnesium or phosphorous if you're an American, or barium salts if you're Chinese

鎂或磷如果你是美國人，或者鋇鹽如果你是中國人。

or Russian. So this document reveals how

或俄羅斯人。是以，這份文件揭示瞭如何

Zirconium is actually ignited. Way on down here on page

鋯其實是被點燃的。在這下面的頁面上

19, there's a graph that shows how ignition temperature

19，有一張圖顯示了點火溫度的情況。

in Celcius is a function of log specific area

(攝氏度)是對數具體面積的函數。

which is the external surface area of the particle of zirconium

即鋯顆粒的外表面積。

ratioed with the mass. So basically as the particle

與品質之比。所以基本上隨著粒子

gets smaller, the ignition temperature gets much easier.

變得更小，點火溫度就會變得更容易。

So you can see that inversely proportional here.

所以你可以看到，這裡成反比。

So, why do we care about that. Well it's just interesting.

那麼，我們為什麼要關心這個。嗯，這只是有趣。

Another thing that's interesting about zirconium is, well, on the periodic table it's

另一件關於鋯的有趣的事情是，在週期表上，它是

way over here, it's very similar to hafnium, it has some of the similar characteristics.

在這裡，它非常類似於鉿，它有一些類似的特點。

One thing that's neat about zirconium is that it doesn't care about neutrons

鋯的一個特點是它不在乎中子。

at all. Neutrons zip right through it, and it doesn't absorb neutrons very

中子會直接穿過它中子會直接穿過它 而它對中子的吸收率並不高。

much at all, which makes it very very nice for the nuclear industry.

多，這使得核工業非常非常好。

It's also very low in terms of it's reaction to

它'的反應也很低，它'的反應。

corrosives, so it's used as cladding for nuclear

腐蝕劑，所以它被用作核電的包層。

reactor fuels. The reason being is the neutrons go through and that

反應堆燃料。原因是中子通過，而那是

energy doesn't get absorbed. This is interesting until

能量不'被吸收。這很有趣，直到

you have a Fukushima type incident, and when you do

你有一個福島類型的事件， 當你這樣做，

start increasing temperature, like we saw earlier on that

開始升溫，就像我們之前看到的那樣

chart, you start to get some reactions. As you can see here

圖，你開始得到一些反應。正如你所看到的

one of the byproducts of that reaction is hydrogen,

該反應的副產品之一是氫氣。

often gas. This is what happened at Fukushima. It built up hydrogen gas

常氣體。這就是發生在福島。它積累了氫氣

when the zirconium started heating up, and reacting, and that

當鋯開始升溫併發生反應時

is what detonated. That detonated and causes all

是什麼引爆。引爆的原因是

kinds of problems. So anyway, now you're Smarter Every Day, and

種問題。所以無論如何，現在你'每天都會更聰明，而且。

if you would help me out, I'd appreciate if you'd pass this along to some of your smart buddies

如果你能幫助我，我''d感激，如果你''d傳遞這個沿一些你的聰明的朋友。

or people who like guns and see if you can help me get some

或者喜歡槍的人，看看你能不能幫我弄到一些。

subscribers. I would greatly appreciate that. Have a great day. Bye.

訂戶。我將非常感謝。有一個偉大的一天。再見。
