It turns out in the case of Hepatitis B, the way the lifecycle proceeds-- the cells make too much of the protein and not all of it gets assembled into the virus.

结果显示,在乙肝的病案中,病毒生命周期的发展情况,细胞制造了大量的蛋白质,但并不是所有的蛋白质都会组合成病毒

In an extreme case b, we had a z effective of 2, so essentially what we had was no shielding at all.

我们有效的z是，所以本质上我们完全没有屏蔽。

It says, in either case in general, t of b-- and this is where I'm going to abuse notation a little bit but I can basically bound it by t, 12 steps plus t of b over 2.

我可以用一个,比12+t的数代表,这里有点不准确的地方,具体的步数依赖于奇数偶数，但是你们可以看到在两个case中。

In the case of the helper cells they stimulate a specific population of B-cells to mature into antibody producing cells, and that antibody is generated against the antigen that stimulated it.

以辅助性T细胞为例,辅助性T细胞刺激特定的B细胞,使这些细胞成长为抗体分泌细胞,抗体分泌细胞产生大量的抗体,以消灭大量增殖的抗原

On the next step though, this, we get substituted by that. Right, on the next step, I'm back in the even case, it's going to take six more steps, plus t of b minus 1. Oops, sorry about that, over 2.

这一步就是偶数了，这一步会让我们得到，6+t这样的结果，因为b-1现在是偶数了,别忽略这里的细节。

t In the b even case, again I'm going to let t of b be the number of steps I want to go through.

如果b为偶数，那么我还是要用,来代表解决这个问题需要的步骤数。
