And this will become more and more clear as we actually talk about these reactions and talk about bonding.
而这将会变得越来越清楚,在我们讨论这些反应以及讨论成键的过程中。
What I think the mutual fund industry has turned into, largely, is a stock picking industry, not a portfolio diversification industry.
我认为,共同基金行业在很大程度上,已经演变成选股行业,而非投资组合多样化行业
As you know, in classical literature the dead are referred to as shades, but here in Milton's simile "shades" merely means "shade trees."

And source critics looking at this material discern numerous, diverse sources that are interwoven throughout.
一些材料批评学家认为这个故事,是由很多素材交织在一起的而成的。
We can tabulate them. We can know them, and then when we have reactions that inter-convert different compounds, we can calculate the heat of reaction is just the difference between the heat of formation of the reactants, and the heat of formation of the products, right.
种化合物的生成热,可以把它们列成表,可以认知它们,而当我们要处理,在不同化合物间转变的反应时,我们只要计算反应物和,生成物的生成热之间的不同,就能计算出反应热。
Is it any coincidence ? that graduates from this university and a handful of others not unlike it ? find themselves in high positions of government, of business, of law, and the academy?
从这所大学毕业的学生,难道都是偶然,而他们有些还在政府,企业,法律相关及学院中执牛耳岗位,将这个阶级形容成?
So that's going to be the end of the exam 1 material, and then we'll move on to exam 2 material, which is kind of exciting, because we've been talking about just individual atoms and ions up to this point, and now we can talk about molecules, so we're going to start talking about bonding.
到此为止就是第一次考试的内容,接下来我们会开始讲第二次考试的内容,这些内容令人有点兴奋,因为我们一直都只是在讨论单个的原子,和离子到目前为止,而现在我们可以讨论分子了,要开始讨论成键的问题了。
They don't really chide his way and I thought it was a terrific scene because... Have any of you seen the more recent remake for televion. It was on Arts and Entertainment about two years ago.
他就演得非常出色,我认为那是最经典的一幕,因为……,你们有人看过根据这部影片,改编而成的电视剧吗?,大约两年前,在《艺术与娱乐》频道上播出过。
The nucleotide has a directionality, there's an up and a down to it and it's going to turn out the chain that's formed by polymerizing these has a directionality as well and that's important in defining the structure.
核苷酸有方向性,有上端和下端,核苷酸长链,是由核苷酸沿一个特定方向聚合而成的,这在定义结构时很重要
There's not two bonds, that's one pi bond, and the reason is because it's 2 p orbitals coming together, and remember p orbitals have electron density above and below the axis, so when they come together, it kind of looks like one bonds, but essentially what we have here is one pi bond.
这不是两个键,这是一个π键,因为这是两个2p轨道组合而成的,记住p轨道在键轴之上,和键轴之下都有电子密度,当它们靠近时,这看着很像两个键,但本质上它是一个π键。
