Working with international colleagues , they have applied dating techniques on the sediment itself and on finds including a land snail , a water snail and a mammoth tooth , all of which came back with an age of around 40 , 000 years 科协家通过放射性碳鉴定技术和激光学鉴定技术断定，这些脚印属于人类，且约有4万年的历史。除此之外，科学家还发现了一只蜗牛一只水蜗牛和一颗猛犸的牙齿，并断定它们也约有4万的历史。
Therefore , we combine computer and cultural relic identify technology , synthesized multi - experts " knowledge and experience and designed a bronze identify expert system model which help archaeologist identify bronze effectively and at the same time speedup sharing and communion of knowledge 为此，本文将计算机技术与文物鉴定技术相结合，综合多个专家的知识及经验，设计了一个计算机辅助青铜器鉴定专家系统模型，旨在帮助考古工作者更加高效地进行青铜器鉴定工作，同时加快知识的共享与交流。
Today , with the rapid development of information and internet all over the world , information security is extraordinarily important , especially , personal identification technology . because biological feature identification technology has unique stability , uniqueness and convenience , it is applied more and more broadly 当今社会高度信息化网络化，信息安全显示出前所未有的重要性，身份鉴定技术具有非常重要的应用价值，生物特征识别技术以其特有的稳定性、唯一性和方便性，得到越来越广泛地应用。
