Use an egress filter on your network to ensure that no packets leave your network with a source address that isn't a part of your internal network.

在网络中使用出口过滤器来确保没有使用不属于你的内部网络的源地址的包离开你的网络。

In recent years, the global construction of information expressway, development of Internet and Intranet, have brought the enormous pushing and impact to accounting profession, accounting by EDP develop from calculating and melting in the early single electromechanics to network accountant of today too, but the network brought a lot of new challenges to accountant at the same time, how to utilize the computer to carry on the work better, guarantee the accountant works and runs in a normal and orderly manner, become the important problem that the accounting profession faces day by day under the network environment.

近年来，全球信息高速公路的建设、Internet和Intranet的发展，给会计行业带来了巨大的推动和冲击，会计电算化也从早期的单机电算化发展到如今的网络会计，但是网络同时也给会计带来了许多新的挑战，如何利用计算机更好地开展工作，确保网络环境下会计工作正常有序地运行，日益成为会计行业所面临的重要问题。

As the popularization of internet and increasing understanding of Electronic Commerce, online shopping market has developed rapidly, an important reason why consumers choose this way is that the transaction costs of the online shopping is lower than traditional way.

随着互联网的不断普及和人们对电子商务的了解程度的增加，我国的网络购物市场发展迅速，消费者选择网络购物一个重要原因，就是网络购物的交易成本相对于传统购物的交易成本要低。

The network era English study must change the backwardness in the traditional study method, and realize the revolution in English study.

我们应该在正确认识网络交往给人的发展带来正面价值和负面影响的基础上，扬长避短，规范和健全网络交往，使网络交往健康有序地发展，从而不断推进人的发展进程。

My paper herein enterprisingly develop a network based instruction support system named"Vclass ", theoretically explore problems involved in the revolution of network based instruction model and instruction activity, where the instruction based on"Vclass"platform is instantiated for study.

该网络教学系统在如下几个方面取得了突破：(1)国内第一个完整集成的网络教学平台，集成了教务管理，网络教学，课程开发工具，教学资源管理四个方面的支持功能，可全面支持网上教学的各个环节；(2)首次将适应性学习的概念引进远程教育中，使得远程教育系统可以针对不同能力层次的学习群体，自动提供不同层次的教学内容。

To solve QoS-constrained routing problem and the problem of balancing network load, an algorithm based on tabu search is proposed, which has a better ability of balancing the cost of the multicast tree and the network load; upon this algorithm, a new algorithm based on degree-constrained and load-balance is proposed, which has a nicer integrative performance on equipoise the cost of multicast tree and the load of links and nodes.

2针对网络负载均衡的QoS问题，提出基于禁忌搜索的负载均衡QoS组播路由算法，算法能平衡组播树代价和网络链路负载均衡状况；在此基础上提出了基于度约束和负载均衡的QoS组播路由算法，算法在满足QoS约束的基础上，均衡了组播树代价、网络链路负载和节点负载三者之间的关系，综合性能良好。

Notice that the solvng ELP problem is equivalent to determine a nonlinear mapping,using the nature that BP neural networks has the parallelism and the capabilities of intrinsic nonlinear mapping,we propose a methods of using back error propagation of ne...

而求解线性规划问题的许多有效方法如单纯形法，Karmarkar's方法等却无法直接用于推广的线性规划问题的求解，注意到推广的线性规划问题等价于一个非线性映射，利用BP神经网络的本质并行性和高度非线性处理能力，该文提出了一类求解推广的线性规划问题的BP神经网络方法，它具有网络构建简单，求解精度高，计算量小等优点，实验结果表明其高效性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
