Definition
发散 is a formal verb meaning 'to disperse' or 'to diverge.' In physics and optics, it describes rays or light spreading outward from a point (divergence). In Traditional Chinese Medicine, it refers to dispersing internal pathogens like heat or wind-cold through the body's surface (often by inducing sweating). It can also be used more generally for gases, clouds, or smells dissipating. Avoid using it for casual 'scatter' (use 散开 instead).
