1907年时，爱因斯坦似乎没能预见到这样的时代，在这个时代，“镭射光钳”发射双重激光，从而困住灰尘一般大小的玻璃微粒，使它们悬浮在空中。
In 1907, Einstein likely did not foresee a time when dust-sized particles of glass could be trapped and suspended in air by dual laser beam "optical tweezers."
北极光的出现是，当太阳发射出带电的微粒子飞越地球时所产生的光线。
The ribbons stretch from one end of the Northern Lights appear when the sun sends charged particles flying toward Earth.
同时，添加剂的加入降低了微粒的表面活性，使低发射率粉体能更均匀地分散在基体聚合物中。
Simultaneously, due to the addition of the additives, the invention reduces the surface activity of particles, so that the low-emissivity powder can be dispersed in the matrix polymer more uniformly.
坏消息是，需要更多的研究是什么超微粒子，究竟是由家庭规模的塑料打印机和超微粒排放的工业规模的3d打印环境的影响发射。
The bad news is that more research is needed on what UFPs, exactly, are emitted by home-scale plastic printers and the impact of UFP emissions in industrial-scale 3d printing environments.
空气质量分析表明，3d打印机可以被描述为“高发射器”的所谓的“超细颗粒”，或超微粒子。
Air quality analysis revealed that 3d printers could be characterized as "high emitters" of what are known as "ultra fine particles," or UFPs.
