Second, China's land available for development to many, such as Beijing, Lin said that the time had come to Beijing, only the Third Ring Road, Fourth Ring Road was not yet out, and then there Sihuan, there are five rings, and now has six ring part of the opening, and the tricyclic tetracyclic ring for each additional one is quite a city the size doubled.

第二，中国的土地可用于发展了许多，如北京，林说，现在已经到了北京，只有三环路，四环路还没有了，然后有四环，有五个环，现在有6个环的一部分，开放和三环四环环，每增加一个城市是一个相当的规模增加了一倍。

An embodiment of a method may include rejecting an arriving packet at a destination node on a semiconductor chip's ring interconnect, e.g., an unbuffered, synchronous ring interconnect, if all of the destination node's buffers are not available, leaving the rejected packet on the ring interconnect to continue traversing the ring, and accepting the rejected packet upon arrival at the destination node, if a buffer is available.

方法的实施例可包括，如果例如无缓冲、同步环形互连(120)的半导体芯片的环形互连上的目的地节点110(1-n的所有缓冲区均不可用，则在该目的地节点处拒绝到达的分组，将该被拒绝的分组留在环形互连(120)上以继续遍历该环，并且如果有缓冲区可用，则当被拒绝的分组到达目的地节点110(1-n之后接受该分组。

According to the researching actualities in ring rolling, this paper researched deeply the basic law of rolling deformation by simulation using ABAQUS software on the base of ring rolling theory and elastic-plastic kinematics explicit FEM. And the residual stress in cold ring rolling was computed by numerical simulation.The mass scaling measures in finite element simulation of ring rolling were researched.

本文针对环件轧制的研究现状，基于环件轧制理论和弹塑性动力显式有限元法，以ABAQUS有限元分析软件为平台，以数值模拟的方式对环件轧制变形的一些基本规律进行更深入的研究，并对环件冷轧时的残余应力进行数值模拟计算。

The ring is rolled by drive roller and mandrel roller, drive roller offer rotation to make ring rotate continuously and mandrel roller offer line feed to make the ring wall become thinner and thinner. The guide roller ensure the ring rolled comfort, and inspect roller check the rings diameter whether reach the limit dimension.

主动辊提供转动，使环件变形区不断循环周而复始的通过轧辊孔型；芯辊提供直线进给运动，使环件壁厚不断减小以实现环件直径扩大的加工过程；导向辊保证轧制平稳进行，检测辊测量轧制环件尺寸是否达到要求以停止轧制。

From the computed ring spacing of three multi-ring basins on the moon (Orientale, Moscoviense and Serenitatis South), it is shown that the tsunami model can only be applied to the area within the main ring, this agrees with the previous conclusion that the Ⅳ ring marks the end of fluidized region and the crater rim of the excavated basin.

通过计算月球上三个多环盆地（东海、莫斯科海和南澄海）的环位置并与观测数据进行比较可看出海啸模型仅适用于主环之内，该环也标志着挖掘盆地的边缘和液化区域的结束边界。
