2011年3月11日,日本大地震引发核泄漏后,民众心态从关注泄漏转变为对核辐射的担忧。特别是由于缺乏预防核辐射的科学知识,各种似是而非的信息,如核辐射污染海水会导致未来食盐供应紧张、吃碘盐能防辐射等开始在网络上疯传。
3月14日,资本市场中的部分游资乘势进行炒作,它们先是大规模吸纳部分盐业股票,接着在尾盘进行拉升,使得其最终在当日大盘整体下跌中逆势涨停收盘。随后又在宁波、绍兴等地将当地食盐抢购一空,制造了局部恐慌,使得“抢盐”风潮愈演愈烈。
这一波抢盐风潮从2011年3月15日晚间开始,以浙江为源头,经网络放大,由东向西和由南向北两种交错传递,迅速涉及全国。无论大城市还是小县城,乃至偏远山村,食盐都成了紧俏商品,有些商店开始惜售食盐,有些商店则借机抬高食盐售价,部分地区的盐价甚至疯涨十倍以上,全国市场的盐几乎被抢购一空。某些盐业类股票再逆势涨停,其他涉盐股票也竞相大涨。
抢盐风潮出现后,国家发改委等部门迅速通过媒体发布权威信息,安定民心。商务部要求中国盐业总公司运用库存向市场紧急投资各种盐产品;科技部约请有关专家针对各种传言释疑解惑……
3月18日,全国各地纷纷出现“退盐”现象,抢盐风潮逐渐平息。涉盐股票的股价也在此后的三个月交易日中持续下跌。

     Quickly, the picture comes alive with hyperlinks (超链接), offering the names of the buildings, towers

and street features that appear in the photo. The hyperlinks lead to information about the history, services

and context of all the features in the photo. You have just hyperlinked your reality.

     That might be a little unbelievable, but the technology exists and is no fevered imagination. This is not

a cool small machine invented for the next James Bond movie; this is a working technology just developed

by European researchers. It could be coming to a phone near you, and soon.

     This, as the marketing types say, is a game changer. It develops a completely new interface (界面) that

combines web-technology with the real world. It is big and fresh, but it goes much further and has much

greater influence.

     The development of the system is most outstanding because image recognition technology has long been

pregnant with promise, but seemed to suffer from an unending labour.

     Now MOBVIS has not only developed image recognition; it has also developed more applications for the

technology; and it has adapted it to the world's most popular technology: the mobile phone.

     The MOBVIS system completely rewrites the rules for exploration and interaction with your physical

environment. The system begins with panoramas (一连串景象). These panoramas form the basis of a city

database. It can match buildings, towers, banners and even logos that appear in the panoramas.

     A user simply takes a picture of the street feature, MOBVIS compares the user's photograph to the

panoramas and then identifies the buildings from the picture you take and the relevant links are returned.

     Then you simply click on the Imks, using a touch-screen phone, and the MOBVIS system will provide

information on the history, art, architecture or even the menu, if it is a restaurant, of the building in question.
