瞪 (dèng) = 'to stare wide-eyed' — gazelles are famous for their huge, alert eyes. 羚 (líng) = 'antelope' (also in 羚羊 'antelope'). So: 'wide-eyed antelope.'

In Chinese business jargon 瞪羚企业 ('gazelle company') describes a fast-growing high-tech startup — borrowed from David Birch's 1990s economics term, picturing a small company that runs and leaps quickly.
