And what you might have noted is although we described how to make predictions about these properties, I didn't talk too much about what it actually means, what the ramifications of these different properties are.
而大家可能已经注意到了我们描述了,如何对这些性质进行预言,但是我并没有讲这到底有什么意义,这些不同性质的分支是什么。
And since the Jewish community is known for owning a lot of different properties,
而且因为犹太人以拥有许多不动产而闻名,
So you see how these different properties of food affect whether we would even consider it a food.
可以看出这些这些不同属性,是如何影响我们判断何为食品的
Now that's not the only thing in cell membranes, there are also proteins in cell membranes, and these proteins are special proteins that can exist within membranes like this, and they exist because these proteins also have different segments with different properties.
但细胞膜并不只由磷脂构成,细胞膜里还有蛋白质,而且这些蛋白质是一些,可以在细胞膜中存在的特殊的蛋白质,而这些蛋白质存在于细胞膜中,源于它们也有溶解性不同的片段
And the reason we didn't do that is because we're actually going to spend much of the rest of the course relating these different properties to the properties of molecules in terms of bonding, and also in terms of chemical reactions.
我们至今没有这样做的原因是,实际上我们这门课程以后的大部分时间都将花在,如何将这些性质与分子的性质联系起来,在成键以及化学反应的方面。
Isotopes have the same chemical identity but different nuclear properties.
同位素有相同的化学特性,但是原子属性不同。
So it's which of these partials are sounding within each of these instruments, and the physical properties of each of these instruments are different.
所以是因为每种乐器发出的泛音不同,每种乐器的物理性质,都是不同的
That matrix has properties that vary in different locations in the body, but basically it's a highly hydrated or water-rich gel.
这种基质的性质,随其所在身体部位的不同而不同,但基本是高度水合的,即富含水的凝胶
If you change the composition, you change the properties. But this is different.
如果你改变组成成分,你就能改变属性,但是这是不同的。
Atoms of different elements have different weights and different chemical properties.
不同元素的原子的质量不同,化学特性也不相同。
If you were to make that change you would find that the molecule now has completely different biological and chemical properties.
如果要做出这样的变化,你会发现,分子的生物形状,和化学性质完全改变了。
Another is how much it's processed and how if you take things that started out as food like wheat or corn, and then they're processed many different ways, and things are added to them or done to them that change their chemical properties, does that affect whether we would consider them food?
另一个是它们被加工过程和程度,比如对于用来食用的麦子和玉米,有很多种加工方式,可以向它们添加一些东西,或进行一些加工去改变它们的化学性质,这会影响我们去判断它们是否为食品吗
