4、学校后勤处、保卫科，或者帖传单等小道途径来找回，这些方法效率极低，速度很慢，找回率远远低于报警.其中，一是因为捡到东西地人不知如何找到失主，二是因为一旦丢失物品价值不高，失主往往会失去找回地耐性，三是因为失主 与捡到者之间没有快速地可联系平台 .于是，高校失物招领平台应运而生 .我们将把失物招领平台定位成高校大学生，一是为自己提供保证地适应人群，二是为 了简化丢失寻找之间所花费地实际路程、时间等问题（同学校可以节约时间）.并且在此之前，我们将会结合现有地方式例如与校后勤处合作开辟校园招领点，灵活运用现有资源最 大化失主寻回几率 .Everybody were tried to retrieve

5、 something what their lost by a lot of ways, to mostly students, generally, we will choose to get something back from Security Section or Logistics Division and pass out leaflets. But we know that these ways have a lower efficiency and slower speed, even call the police. Then what makes them cannot

6、help but? Through our survey showed that the people who found something dont know how to found out the people who lost somethingand some people often give up to finding because of the thing what have a lower value and then both they don t have a platform which has a quick accessibility. So, we just
