退避

Problem solving, withdraw, ask for help and restrain could reduce the negative moods caused by college entrance examination stress, while illusion and abreaction could increase them.

4问题解决、退避、求助和忍耐的应对方式可以减轻学生在高考应激中的消极情绪，而幻想和发泄的使用对消极情绪的减轻是不利的。

Brinkmanship: The practice, especially in international politics, of seeking advantage by creating the impression that one is willing and able to push a highly dangerous situation to the limit rather than concede.

边缘政策：通过创造一种印象来寻求利益的国际政治实践，即一个人情愿并能够把高度危险的局势推到极限而不是退避。

The students from countryside own more mean value than from cities on"learning stress","castigation","loss"and sum value. 2、College students" coping styles for stress include"problem solving","help seeking","retreat","fantasy","rationalization"and"self-blame, whose frequency is from high to low.

大学生应对方式各因子得分从高到低依次为：解决问题、求助、退避、幻想、合理化、自责，从总体上来说应对方式还是比较成熟的，在具体各因子上存在一定的性别、年级、专业差异。

This algorithm defines route valid term,the father node priority queue,and proposes the overlapping backoff window strategy.Simulation result shows this algorithm can construct the route tree effectively.
