Some theories suggest that the quantum nature of space should manifest itself at the ‘Planck scale’: the minuscule 10-35 of a metre, where a millimetre is 10-3 m.
一些理论物理学家认为宇宙的量子本质应该在“普朗克常数”范围内：即十的负三十五次方米，而一毫米才不过十的负三次方米。
A static magnetic field is measured in units of ampere per metre, (A/m) but is usually expressed in terms of the corresponding magnetic induction measured in units of tesla, (T) or millitesla (mT).
静电磁场以每米具有的安培单位衡量(A/m)，但是通常以相应的电磁感应单位特斯拉(T)或毫伏特斯拉(mT)表示。
