...技术中,分子束磊晶法的主要优点是低温 (至),因此减少了自动掺杂 (autodoping),及掺杂区内的掺杂原子向外越界扩散 (out-diffusion) 的现象.但分子束磊晶法最大的优点可能是:在一个制程步骤 (抽一次真空) 内可在晶圆表面形成多层的能力.

And, I'm going to have to explain to you, where does it come from? OK, but before I do that, well, let me point out actually that the equation is not just the diffusion equation.
给你们解释一下，这个从哪儿来？，在我解释之前，告诉大家，这个方程不只是扩散方程。
Diffusion is when you have a fluid in which you are introducing some substance, and you want to figure out how that thing is going to spread out, the technical term is diffuse, into the ambient fluid.
扩散就是，当在某液体中加入某物质时，想算出该物质怎样在周围的液体中散开，专业术语叫做扩散。
