  • 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]

    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.

  • 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。
