鳌鱼灯以龙首鱼身为主要特征，是“巨鳌戴山”神话的又一种生动演化。鳌鱼既拥有“鳌”负山载物的神力，又融合了“鱼”的丰富意象，如鲇鱼（年年有余）、金鱼（金玉满堂）、鲤鱼（鱼跃龙门）等。受科举文化影响，鳌鱼灯最具有代表性的寓意则源自“独占鳌头”的典故。在民间，鳌鱼又被称为“龙鱼”，是鱼化龙的过渡形态，因此它又代表着积极进取的精神。正因融合了从生活富足到功成名就的多重美好寓意，鳌鱼灯成了最受民间欢迎的灯彩之一。《上元灯彩图》所描绘的灯市中，鳌鱼灯不仅数量可观，且造型变化多端，正是其广泛群众基础的生动体现。
and like i said, the DFA can also be infinite, but it “blows up” at a rate of at most one state per character in the input, so it will terminate and likely not cause any real issues. the number of states is bounded by the maximum context distance that you need to keep track of for lookarounds, so using infinite context patterns like a(?=.*b) will never create more states than the length of the longest line in your input.，详情可参考爱思助手下载最新版本
