What's in your iPhone
你的智能手机里有些什么？
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.
人们已经排起长队准备购买iphone 6。经过连续几个月的传闻后，我们终于得见其庐山真面目，了解其真正的性能。
But how much do you really know about that piece of technology in your pocket?
但是你对自己口袋里的智能手机相关的技术了解多少呢？
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，一部典型的智能手机含有大约300毫克银和300毫克金。仅今年用来生产手机的金和银的价值就超过25亿美元。我们在CompoundInterest的朋友们查阅了元素周期表，鉴别出数十种其他元素，也可以用于制作智能手机。
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.
如果没有电池，那么你的手机什么都不能做。其能量来源与锂电池最为接近。那些电池使用锂钴氧化物来作负极或正极，用碳或石墨来作阴极或阳极。阳极生成电子，阴极吸收电子来形成溶液，为手机提供能量。一些手机电池使用锰来代替钴，几乎所有手机电池，甚至整个手机都是用铝包裹。
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镜子，但是手机屏幕实际上包含地球上最稀有的元素。都是非常少量的物质，你或许从来没有听说过，比如镨， 铽，钇和钆，帮助生成手机屏幕上的颜色。
