1·The bugs, which are less than a millimetre long, feed on scales of human skin and produce allergens which are easily inhaled during sleep.
这些体长不超过一毫米的虫子以人类皮肤的鳞屑为食，并且产生的过敏原在睡眠时很容易被吸入。
2·These sections are dissected, using a laser, into slices a millimetre or less thick, and then scanned again, either with the micro-CT or with a scanning electron microscope.
采用激光将这些小岩石块切分成一毫米或不太厚的薄片，然后用微CT机或电子显微扫描镜对其再次扫描。
3·Nanocrystals, also known as quantum dots, are semiconducting particles with a diameter of a few millionths of a millimetre.

5·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)。
1·Swiss geodesists, who have already been measuring the Alps with highest accuracy for decades, have observed, however, that the Alp summits, as compared to low land, rise up to one millimetre per year.
已以最高的精确度测量阿尔卑斯山数十年的瑞士测地学家观察到：尽管阿尔卑斯山最高峰，与低地相比，每年升高1公厘。
