But from a certain nameless awe with which the mad assumptions of the mummer had inspired the whole party, there were found none who put forth a hand to seize him; so that, unimpeded, he passed within a yard of the prince's person; and while the vast assembly, as with one impulse, shrank from the centers of the rooms to the walls, he made his way uninterruptedly, but with the same solemn and measured step which had distinguished him from the first, through the blue chamber to the purple -- to the purple to the green -- through the green to the orange -- through this again to the white -- and even thence to the violet, ere a decided movement had been made to arrest him.

大伙儿看到来者如此狂妄，早已吓坏了，哪儿还有什么人胆敢伸出手去把他抓住啊？因此，这个不速之客竟然通行无阻的走到王爷面前，相距咫尺。这时，那一帮子跳舞的人都情不自禁的纷纷从屋子中间退避到墙跟前，他就趁此脚不停步的朝前走，步子还是象先前那样不同寻常，既稳重，又匀调，一步一步的走出蓝色的一间屋子，走到紫红色的一间，出了紫红色的一间又走进橙黄色的一间，由此又走进白色的一间，再由此走进紫罗兰色的一间，于是王爷才决定采取行动逮住他。

But, the fairness of middle links will be affected due to the hidden terminal and make the throughput badly descend. This paper proposes a new way based on data retransfer ratio. When the data retransfer ratio increase, dynamic reduce the size of contention window of backofftimer, enhance the probability of use channel and improvement the TCP fairness.
