VLAN ；三层交换；网络风暴；网络管理

The result is that in none of the bridges believing there is a loop and when a broadcast packet is sent on the network, a broadcast storm results over the entire internetwork.

这个结果导致没有一个交换器会知到这网路中有一个回圈存在。当有一个广播封包产生时，整个网路就会产生广播风暴。

Ta group: After retinal vein was occluded by the same method used as above, a venipuncture is performed in the locations away from the occluded site about 2/3 to 1 PD distance, a 20G needle tip was used to puncture the retinal vein and underlying retina and the Bruch s membrane.

We found a lot of "good" things: Pai Qishan and the principle of exchange of hot and cold air base station to replace the engine room inside the air-conditioning, to achieve the effect of reducing power consumption, it is really a good idea; education in remote video platforms around the Zu Buchu school teachers teaching skills can be a PK, saving a lot of traffic and the cost of the emissions, conditional schools should have no reason to reject it; use of SMS, MMS study the "scientific concept of development", certainly than Daidai De-in the office listening to read documents more effective leadership, Why not

我们发现了很多"好"东西：用排气扇和冷热空气交换的原理取代基站机房里面的空调，从而达到降低电力消耗的效果，这真是一个不错的主意；在远程视频教育平台上各地的老师足不出校可以进行教学技能大PK，节省了大量的交通成本以及带来的尾气排放，有条件的学校应该没有理由拒绝它；利用短信、彩信学习"科学发展观"，肯定比聚在办公室里呆呆地听领导读文件更有效果，何乐而不为？

With scheduling algorithms FIFO,the communication model is set up and network elements' arrive curves and service curves are derived for a switched industrial Ethernet model with two levels' tree topology.Then,analytic expressions of the worst case end-to-end delay,buffer size and output burstiness are presented,the maximum network delays of real-time data are calculated based on derived results.

This paper presents an IFMC CAD model that consits of a geometry model and a material model, in which the geometry space acts as a base space and the material space acts as a bundle space. In this CAD model, the geometry model is based on the non-manifold model. In addition, a half-face data sturucture, which is derived from the half-edge data structure with the non-manifold feature of IFMC taken into account, is adopted to represent the geometry and topology information of the component. For the material model of IFMC, this paper focuses on the FGM component representation firstly and present a simplex-subdivision based CAD data exchange format, in which the material information is represented as a (n-1) simplex and material distributing feature is represented by the interpolation on the simplex-subdivision. Based on those, a part-building orientation optimization algorithm and an adaptive slicing algorithm for FGM component are presented in the paper. For the IFMC material model, the IFMC material information representation is divided into a meso-scale and a macro-scale representation. In the meso-scale, a concept named parameterized periodic functional meso-structure is presented as a unique form to represent the FGM (the homogeneous materials are regarded as a special FGM), the composite and the functional meso-structure material. The model of PMS is a three-tuple that contains the space state informatation, the material parameter and the material meso-scale distribution feature. The macro-scale material information representation is similar to the FGM components by interpolation of the control parameter of the periodical functional meso-structure based on the simplex-subdivision. Through an example of manufacturing-oriented IFMC CAD data processing, it is proved that the IFMC CAD model and the material information representation and process method proposed in this paper can provide a reliable data support for IFMC digital concurrent design and manufacturing.

本文将理想材料零件CAD模型建立在以几何空间为底空间、以材料空间为丛空间的结构上，使用非流形几何模型作为理想材料零件几何拓扑模型的基础，并在半边数据结构基础上，针对理想材料零件的非流形特征局限内部边界上的特点，给出了一个半面数据结构来表述零件的几何拓扑信息；对于理想材料零件的材料模型，本文先从功能梯度材料零件的信息表述与CAD数据交换和处理入手，将材料信息表述为（n-1）维单纯形，然后通过对三维几何区域的单纯剖分，以插值的方式表述零件材料分布特征；在此基础上，根据功能梯度材料零件分层制造中对CAD数据处理的要求，给出了综合考虑零件几何特征与材料特征的生长方向优化算法和自适应切片算法；而对于文中所定义的理想材料零件，本文将其材料信息表述分解到细观和宏观两个尺度进行，首先给出了细观尺度上参数化的周期性功能细结构概念，以此来统一表述功能梯度材料（单质材料作为特殊的功能梯度材料看待）、复合材料和功能细结构材料；把周期性功能细结构模型化为一个包含空间状态信息、材料构成参数和材料细观分布特征参数的三元组，以表达零件的细观材料特征；对于零件宏观的材料变化特征，则同样在几何区域单纯剖分的基础上，通过对细观尺度上周期性功能细结构控制参数的插值来完成；通过理想材料零件CAD数据处理的算例，验证了本文中理想材料零件CAD模型及材料信息表述与处理方法完全可以为理想材料零件的数字化制造提供可靠的数据支持。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
