Macroscopic scale 宏观
(重定向自Macroscopic)
The macroscopic scale is the length scale on which objects or phenomena are large enough to be visible practically with the naked eye, without magnifying devices.
When applied to physical phenomena and bodies, the macroscopic scale describes things as a person can directly perceive them, without the aid of magnifying devices. This is in contrast to observations (microscopy) or theories (microphysics, statistical physics) of objects of geometric lengths smaller than perhaps some hundreds of micrometers.
