Well, the energy of the photon, hv we know from Planck, is h nu, which is hc over lambda.
好吧,光子,我们从普朗克那得知,它是,即hc/lambda,波长。
If I take lambda equals one angstrom, hc/lambda go through hc over lambda, you will discover that the energy of a photon with one angstrom as its wavelength is on the order of 12,400 electron volts.
如果我让波长等于一埃,能量为,你将发现光子的能量,当其波长为1埃的时候,相当于12,400电子伏特。
One of the functions of MHC is to indicate which cells belong inside your body, which cells don't.
HC的功能之一,是区分哪些细胞属于你的身体,而哪些不属于
UC So we can immediately write delta u C is Cv times T1 minus T2. Delta Hc C is Cp times T1 minus T2, right?
所以我们可以直接写出△,是Cv乘以,△HC是Cp乘以,对吧?
hc/lambda There is no hc over lambda.
这儿没有。
It's what makes my cells my cells, and your cells your cells.
HC分子能区别我的细胞,和你的细胞
The other thing that it does is that when a virus is inside these cells making its proteins, some of those proteins get processed or digested into small fragments that are themselves antigens.
HC的另一项作用是,当病毒在细胞内表达蛋白时,一些蛋白被加工,或者,分解成小片段而成为抗原
