What's in your iPhone
你的智能手機(jī)里有些什么？
The lines are probably already forming for the new iphone six. After months and months of rumors, we finally know what it will look like, and what kind of horsepower it’s packing.
人們已經(jīng)排起長隊準(zhǔn)備購買iphone 6。經(jīng)過連續(xù)幾個月的傳聞后，我們終于得見其廬山真面目，了解其真正的性能。
But how much do you really know about that piece of technology in your pocket?
但是你對自己口袋里的智能手機(jī)相關(guān)的技術(shù)了解多少呢？
For instance, a typical smartphone contains about 300 milligrams of silver and 30 milligrams of gold. The gold and silver used to manufacture phones this year alone are worth more than 2.5 billion dollars. Our friends over at Compound Interest pulled out the periodic table and identified dozens of other elements that are also packed into a typical smartphone.
例如，一部典型的智能手機(jī)含有大約300毫克銀和300毫克金。僅今年用來生產(chǎn)手機(jī)的金和銀的價值就超過25億美元。我們在CompoundInterest的朋友們查閱了元素周期表，鑒別出數(shù)十種其他元素，也可以用于制作智能手機(jī)。
You can’t do anything on your phone without a battery. And that power source is most likely a lithium-ion battery. Those batteries use lithium-cobalt oxide for the cathode or positive side, and carbon or graphite for the negative side, called an anode. The anode produces electrons, and the cathode absorbs them to produce the juice that powers your phone.Some phone batteries use manganese in place of cobalt, and almost all phone batteries,and often the entire phone, are encased in aluminum.
如果沒有電池，那么你的手機(jī)什么都不能做。其能量來源與鋰電池最為接近。那些電池使用鋰鈷氧化物來作負(fù)極或正極，用碳或石墨來作陰極或陽極。陽極生成電子，陰極吸收電子來形成溶液，為手機(jī)提供能量。一些手機(jī)電池使用錳來代替鈷，幾乎所有手機(jī)電池，甚至整個手機(jī)都是用鋁包裹。
It may just look like a piece of glass, but that smartphone screen actually contains some of the rarest elements on earth.Very small quantities of things you’ve probably never heard of like praseodymium, terbium, yttrium and gadolinium, help produce the colors on a smartphone’s screen.
屏幕看上去就像一面鏡子，但是手機(jī)屏幕實(shí)際上包含地球上最稀有的元素。都是非常少量的物質(zhì)，你或許從來沒有聽說過，比如鐠， 鋱，釔和釓，幫助生成手機(jī)屏幕上的顏色。
