1·In an ultracapacitor, the distance between the ions and opposite-charged electrode is so tiny it's measured in nanometers (one-thousandth of a micron).
在超级电容中，离子和带相反电荷的电极之间的距离非常小，需要用纳米（千分之一微米）计算。
2·The technology is producing cells that are often only two microns thick (a micron is one-millionth of a meter).
这项技术制造的电池厚度通常仅仅是两微米(一微米是一个百万分之一米)。
3·Ash particles are normally in the 50-100 micron (0.05 to 0.1 millimetre) range.
灰尘颗粒一般都50—100微米(0.05—0.1毫米)。
4·Studies of ash captured from the air show that for every one of the largest particles (about 300 microns) there are a million or more in the 2 micron range.
获取飘移在空中的颗粒，研究发现：每一批最大的颗粒(约300微米)中有100万或更多的颗粒小于2微米。
5·As a result, the makers have developed a generation of cells whose silicon layers are only a micron or two deep, as opposed to the usual thickness of 200-300 microns.
因此，制造商开发出了新一代的电池，这种电池的硅层厚度只有一至二微米，而不是通常200 - 300微米的厚度。
