If you took a 15 inch artillery shell moving at the velocity it typically goes at, and take that amount of kinetic energy versus the resistive capacity of a sheet of tissue paper, that's the scale that we're looking at here.
如果你有1个15英寸的炮弹,按照经典的速度移动，会消耗大量的动能,抵抗来自于一张薄纸的阻力，这就是我们在这儿看到的尺度。

And he gave a very good analogy in saying, "It was almost as incredible as if you'd fired a 15 inch shell at a piece of tissue paper, and it came back and hit you."
他还打过一个很好的比方：,“这就像是,你用个15英寸果壳,打到面巾纸上被弹回来打到你，一样不可思议，“

Again, in the context of a specific tissue site, in this case it's the nervous system.
当然又是放在某种组织当中来说,这次是在神经系统

Huxley points out, "How it is that anything so remarkable as a state of consciousness comes about as a result of irritating nervous tissue, is just as unaccountable as the appearance of the Djinn " - of the genie " when Aladdin rubs his lamp."
赫胥黎提出,"刺激人的神经组织,便能产生像意识状态这般奇异之物,这就好比阿拉丁一擦神灯,巨神灵就闪现出来一样魔幻,无法解释

That cells that form tissues often have junctions that hold them together so that they don't fall apart and they exist as a solid piece of tissue.
组织细胞通常通过,细胞连接而联系在一起,所以它们不会分散开来,而保持坚固的组织形态

Other kinds of microorganisms reproduce and cause tissue damage in a different way.

It involves putting a needle, a fairly large needle into usually one of the pelvic bones and collecting marrow from which is tissue that's deep inside those bones.
先要用针头,相当大的针头刺进你的盆骨,然后进行收集,这些在骨头深处的骨髓

often a biologist can discriminate between different kinds of cells that they see in section of a tissue for example, merely by its shape and the characteristics that it has.
生物学家经常可以在组织切片上,仅凭所看见的细胞形状来区分不同细胞,如果举例来说的话,仅通过细胞的形状和特性就足够
-
It's also an example of a tissue specific stem cell.
这同时也是一个组织特异性干细胞的例子
-
A progenitor cell, the definition, it just means it can generate the cells that are typical of that tissue or that organ, so it's capable of becoming these mature classes of cells.
祖细胞的定义就是,它能产生那个器官或者组织内的,所有的典型细胞,所以它可以成为那一类的成熟细胞
-
The other is that this kind of adherence gives the tissue a property that's useful, in this case the property is it can serve as a barrier to nutrients from entering our body.
另外这种黏附,给予组织一种非常有用的属性,这种属性表现为组织成为,营养物质进入身体过程中的屏障
-
There are cells within your body that are always in the process of division and forming new cells, and sometimes this is for a tissue where cells only have a finite lifetime.
你体内的一些细胞,始终在不断分裂,并生成新的细胞,很多时候,是在一些细胞寿命有限的组织中
-
Then we talked a little bit about the sort of physics of what holds cells together to form a collection of cells, a tissue and to make up the structure of our body.
之后我们也谈了一点有关于,使细胞聚集形成组织,进而成为身体架构的物理原理
-
What extracellular matrix you have in any particular tissue is there because there's a balance between it being produced by one kind of cell and digested by another, and you're in this sort of state of dynamic equilibrium.
特定组织中,细胞外基质的多少,取决于一个,分泌与降解的平衡,这是一种动态的平衡关系
-
So two different kinds of strategies, one is a surgical strategy, actually removing tissue and we talked a little bit about the engineering of surgical instruments and things like - so there's a lot of Biomedical Engineering that goes into everything that happens in the operating room.
这是两种不同的方法,其中之一是通过手术,切除组织,之前我们讲过的手术器械工程学,这涉及到许多生物医学工程学原理,它已经渗透到手术室内的方方面面
-
This is introducing a gene, it's a natural gene but it's not - it's a natural gene that's found in humans and is actually expressed all over your body in different levels, but you're concentrating it or over expressing it in one particular region of tissue in order to have a particular effect.
通过导入一个基因,这是一个天然基因但--,是一种于人体内发现的天然基因,在全身细胞中都有不同程度表达,但需要集中在组织的某一特定区域,表达或过表达,才能达到特定疗效
-
It allows us to look not just at the anatomy of what's going on inside your body like an x-ray does, but to look at the chemistry, the biochemistry of what's happening inside a particular organ or tissue in your body.
这种方法不仅能够像X射线那样,使我们从解剖学的角度观察体内的情况,还能了解到,在体内特定的组织和器官中,发生的化学 确切说是生物化学过程
