The problem is that the theory puts white dwarfs magnetic fields at 100,000 tesla or more,well beyond humanity s reach.
问题是,这个第一原则认为白矮星的磁场强度可以达到100,000特斯拉或者更多,远远超过了人类的极限。
Dr Murdin built his own little white dwarf to see if the theory looked good.
穆迪博士建造了他自己的小白矮星,想弄明白这种理论是否真的正确。
It consists of a silicon crystal sprinkled with phosphorus atoms.
这个小白矮星由布满磷原子的硅晶体组成。
A silicon atom has four electrons in its outer shell.
一个硅原子外有四个电子。
In a crystal, all four are used to bind it to neighbouring atoms.
在晶体中,所有的四个电子都是与其相邻的原子紧紧捆绑在一起。
Phosphorus has five outer electrons.
磷原子外有5个电子。
Insert a phosphorus atom into the silicon lattice and you are left with an unused electron.
把一个磷原子嵌入到硅晶格中,那还剩下一个电子。
Since phosphorus also has one more proton in its nucleus than silicon does, taken togetherthe extra particles resemble a hydrogen atom: a single electron tethered to a singleproton.
