A number describing the size of a carbon atom would be meaningless in a society that had no notion of atoms or building blocks of that scale.
描绘一个碳原子大小的数字在没有原子概念或者对没有构建这样的数值范围比例的社会是一点用处也没有的。
But a magnesium atom would carry two electrons, so a battery storing a given amount of energy could be nearly halved in size and weight.
但镁原子每次可以携带两个电子，这样的话在储存相同能量时可以使电池的大小和重量减半。
And all it does is say that we're going to divide up our available volume into little bits that are basically the size of an atom or a molecule, or whatever the particle is in the gas phase.

几十年来，粒子物理学家们用氢原子作为基准衡量质子的大小。
The VNB101 upgrades to an Atom N280 processor, but strips out some features of the 100 in order to reduce size and weight.
另一款VNB101则将处理器升级为AtomN280，不过缩减了VNB100的部分功能，以便减轻重量缩小尺寸。
At some point you will cut the magnet so small that you will have cut down to the size of a single atom.
从某个方面看，(如果你一直切下去，)你会把磁体切到如此之小，小到只有一个单原子那么大。
However, the mean atom distance depends on not only the cluster size, but also the cluster structure, which can be regarded as the criterion of determining the structure transformation.
平均原子间距不但依赖于团簇的尺寸，且对团簇结构的变化敏感，可以作为非晶与密堆结构晶体转变的一个判据。
Research results indicate that the pore geometry of the rock and soil shows the fractal behavior over the range from atom scale to grain size.
大量的研究表明，岩土介质的孔隙几何从原子尺度到晶粒尺寸范围内均表现出分形特征。
It is shown that the atomization energy per atom increases with the cluster size.
研究表明：随着团簇尺寸的增大，单个原子的平均原子化能逐渐增大。
Enlarge an atom to the size of the earth. The nucleus in it would be only about as big as a basket ball.
假如把一个原子放大到地球那么大，他的核子也只不过一个篮球那么大。
A structure the size of an atom represents a fundamental limit: to make anything smaller would require manipulating atomic nuclei—essentially, transmuting one chemical element into another.
单原子的结构是个基本极限：若要做得更小，基本上就得操控原子核了，这可是把一种化学元素转换为另一种。
If the whole atom were the size of this theater, its nucleus would be like a speck of dist. Yet the nucleus contains almost all of the atom 's mass.
如果把整个原子的尺寸看成电影院大小，它的核则如同一粒灰尘大小，然而原子的质量几乎全部集中在原子核。
Imagine a data storage device the size of an atom, working at the speed of light.
想像一下数据存储装置只有原子大小、并以光速工作。
A nucleus is about one billionth the size of an atom.
原子核的体积大约是原子的一万亿分之一。

如何确定原子的重量和体积，是我们许多人感兴趣的一个问题。
Researchers usethese X-ray flashes to resolve structures as small as one ten billionth of ameter (0.1 nanometer) in size. That is roughly the diameter of a hydrogen atom.
【译】研究人员用X射线光来分辨尺寸为百亿分之一米（即0.1纳米）的微小结构，这种尺寸结构接近氢原子直径。
Over these distances, the distortions of space are approximately a billionth the size of an atom-sufficient to cause noticeable differences in the phase of the combining light beams.
在这么长的距离之下，即使只有十亿分之一个原子大小的空间扭曲，也足以使光束在合并时出现相位差。
