文档介绍：网络拍卖中的欺诈行为
several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size标联盟在第二价拍卖的条件下有组织串谋的特征。在可替代物品或互补物品的多元拍卖中同样存在此现象。也提出了第一价拍卖的投标联盟协议。最后，我们给出一些案例说明投标联盟在任意的拍卖机制下的自我协作协议。在拍卖过程中,一组竞买人合谋而形成一个圈。圈内的成员承诺互不竞争。拍卖结束以后,如果圈内的某一成员中标,那么该物品在圈内成员之间再次拍卖,将第一次拍卖价格与第二次拍卖价格之差作为利润在圈内成员之间分配。网络使得圈的形成更加容易,竞买人可以使用加密机制使他们的聊天室形成一个圈,即使缺乏这种集中的聊天室,如果竞买人的身份相互都知道,也很容易形成圈。设置保存价格能有效地减少圈的形成。

Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured
