That is what makes metal so fascinating, because metallic bonding allows the atoms to glide over one another without resulting in catastrophic failure.
所以这就使得金属具有了特别的性质,因为金属键使得原子可以,在彼此之间流动,而不会千万灾难性的后果。
You might have brought in investments or something by borrowing money, so the investment--the combined investment and liability could be very volatile.

How can a utilitarian distinguish qualitatively higher pleasures from lesser ones, base ones, unworthy ones? Yes?
功利主义者何以将性质上更高级的快乐,与较低级,基本无价值的区分开呢,请说?
Alan Turing In 1936, that same guy, Alan Turing, showed that with six simple primitives, anything that could be described in a mechanical process, it's actually algorithmically, could be programmed just using those six primitives.
在1936年,还是那个人,展示了六个基本类型,可以在计算过程中,表达出任何含义来,其实这是演算性质的,可以根据六个数字编程。
It means that the properties of the system, the properties that describe the system, don't change in time or in space.
它的意思是指,用以描述系统的性质,不随时间或空间改变。
So certainly we would expect to see that it has an effect in terms of seeing its wave-like properties.
所以我们当然可以预期,会看到波动性质的效果。
OK, now what we'd like to do is be able to calculate any of these quantities in terms of temperature, pressure, volume properties.
现在我们想要做的是能够利用,温度,压强和体积的性质,计算上面的物理量。
So, this is just one example of how these properties can already, even our understanding just talking about single atoms, can already make an impact in these biological systems.
这只是一个例子,通过它我们可以看到,尽管我们仅仅讲到了单个原子,但我们现在已经可以用它的性质来理解一些生物系统。
That's important because one of the attributes of stem cells is that they remain at their site and capable of reproducing themselves.
这非常重要,因为干细胞的性质之一,就是它们能维持自身的状态,并能进行再分裂
The sort of thing that perhaps we might call or think of as abstract objects or abstract properties.
这类事物,我们可能需要称作或认为是抽象的现实,或抽象的性质
Now, if you are a private company, you are limited to where you can sell your investments.
如果你的公司是私募性质,在推销投资产品方面会面临许多限制
We started with this hypothesis of octet stability and I'm talking about properties of ionic crystals.
我们从八隅律的稳定性假设开始,我们讨论到了离子晶体的性质。
It's in the nature of things to go at a constant velocity.
能保持恒定速度是物体的固有性质
So, instead, it was amazing he was able to group things in terms of the properties that he saw.
但是,他能够仅仅通过自己知道的那些性质,就能对元素进行归类,这是非常难得的。
And temperature then is associated with property And if it had changed, then the temperature between those two would have changed in a very particular way.
就与这种性质有关,如果它发生了改变,说明这,两者的温度,以特定的方式发生了改变。
And this spin is an intrinsic quality of the electron, it's a property that is intrinsic in all particles, just like we would say mass is intrinsic or charge is intrinsic.
自旋是电子的本征量,它是所有粒子的本征性质,就像我们说质量是本征的或者电荷是本征的。
And an electron is something where, i n fact, we might be able to, if we calculate it and see how that works out, actually observe some of its wave-like properties.
如果我们对电子做计算,并且知道如何算出来的,那么我们是可以观测到,电子的一些波动性质的。
And what we've been talking about with all of these properties are, of course, how can we figure out what that is for a certain atom by looking at the periodic table, so we want to think about the periodic trend for atomic radius.
对于我们讲过的这些性质,我们所讨论的一直都是,当然是,我们如何能够判断某一个原子的这些性质,通过观察周期表,因此我们需要思考一下原子半径的周期性规律。
A capability for asymmetric division and the production of cells that become differentiating more mature cells, those are properties of stem cells.
能够完成不对称分裂,以及产生细胞,并分化成为一些更成熟的细胞,这些是干细胞的性质
But you actually need to keep a few caveats in mind as you do this, which is the fact that trends predict a lot of chemical properties, but they can't predict everything in terms of biological properties.
不过在你使用的过程中,需要牢记一些注意事项,那就是元素周期律可以预言很多化学性质,但是不能预言一切性质,比如生物学性质。
And there's a certain property associated with heat flow with b and it didn't change.
