Conference organizer, Dr.Greg Pappas of the American non-governmental organization,or NGO, called Interaction says that while it is too early to tell whether the current outbreak will turn into a global pandemic, poorer countries in particular need to be prepared for the day when one does hit.

All right. The other thing I have to teach you is matter-energy interaction so that we can see how the Balmer series validates the Bohr model.
好的,我要教你们的里一个知识点是,物质能量的相互作用,我们可以见证,巴尔末线系是怎样证实波尔模型的。
There's not actually chemical covalent bonds that are formed but it's a non-covalent interaction, usually dominated by hydrogen bonding.
所以配体和受体之间不生成共价键,这是一种非共价化合反应,它们通常以氢键相联
But it's also possible-- actually compatible with accepting that fact-- there are two additional possibilities, that there might be some negative interaction effects.
但同样也有可能-,事实上与接受这个事实一致-,有另外两种可能性,可能会产生负面的相互影响。
PROFESSOR: And this is a question based on where we left off on Wednesday -- we were talking about Coulomb's force law to describe the interaction between two particles and good job, most of you got this correct.
教授:这是我们上次最后,留下的问题-我们讲到,描述粒子间相互作用的,库伦定律,很好,大部分人都做对了。
if that's something you're familiar with - in which the interaction of real people with what are called "Toons" in that film is part of the film's pleasure. The boundary between different levels of reality is crossed.
如果你们对这个比较熟悉的话,在电影里一个被称为“Toons“的卡通形象和真人互动“,这是那部电影的好玩之处,在那里不同层面现实的边界交叉了。
As always with philosophy, there's more complicated versions of dualism where maybe the interaction doesn't work both ways, but let's just limit ourselves to good, old-fashioned, two-way interactionist dualism.
但由于我们在说的是哲学,二元论还持有更为复杂的观点,例如,交互作用对双方都不起作用,但就让我们限制在一个范围内较好,保守的,双向互动二元论观点
Does the fact that death follows life-- does that produce any interaction effects between the two, which need to be added into our formula-- ? added into the mix as well?
那生后即是死这个事实-,有没有在这两者间产生任何相互影响,也需要被增加到我们的公式中来-,要增加到混合中来?
It could be that in thinking about the nature of the combination we're led to see that in certain ways the combination-- the interaction effects--are negative, are bad ones.
可能在考虑这种组合的本质时,我们看到了再某些方面这种组合-,相互影响,是负面的,是不好的。
The second possible thought that comes to mind for me, in thinking about the negative interaction effects, I call under the title-- I think about under the title-- " "How the Noble Have Fallen."
在考虑负面相互影响时,我想到的第二种可能性,我把它叫做-,我想它叫做-,“贵族如何没落“
Now, usually this is a non-covalent interaction.
这通常是一种非共价化合反应
So, two-way interaction.
所以这是种双向互动
We're going to talk about this kind of non-covalent interaction more when we talk about the immune system, because one example of ligand and receptors that's important in the immune system are antigens - foreign molecules, and antibodies - molecules that we produce.
当我们讲到免疫系统的时候,会更详细地谈到这种非共价化合反应,因为在免疫系统中,一个重要的配体受体结合反应,就是抗原,即外源分子,与抗体,这个人体自身产生的分子结合
Immune cells recognize it, and they recognize it by a very special form of receptor-ligand interaction where the ligand is MHC1 with the foreign antigen and the receptor is a receptor called the T-cell receptor complex.
免疫细胞识别出染病细胞,通过一种特殊形式的,受体配体协作机制识别出来,其中的配体是同,外源抗原共同出现的MHC1,而这其中受体是T细胞受体复合体
