(单词翻译)

   Yes, the mosquitos are swarming2 at this time of year. Alaska joke the B.Z. the sate3 bird. But have you ever looked closely the swarm1 making mosquitos the nuts images? It is a curious thing. The swarm maintains the kind of shape that moves around. But the bugs4 inside it seem to flirt5 around randomly7, rather than flocking like birds. These collective yet disordered flight interest physicists8 in Rome. They shot auto9 slow motion videos of swarming images. Then they map the flight of each image, and did the mathematical analyses of the collective behavior. Their finding: the motion of the images is not random6. The bugs stay far enough apart to avoid knock into a formation. The swarm instead expands as needed to stay just below the reshall? density10. The work appears on the site Alkida Work? . Flocks and schools move in formation only once the group reaches the critical density. Below that reshall? the individuals move. Well, like images. Insectivores in full-fledged flocks may be a reproductive strategy. After all, it is hard to mingle11 if you start a line dance.
