一位名叫RD.的朋友提供的算法，我用我的和一个朋友的成绩验证了一下，都是正确的。

使用如下的EXCEL计算就可以了。

In home networking, port forwarding, also called port mapping or punch-through, enables you to create a permanent translation entry that maps a protocol port on your gateway machine to an IP address and protocol port on your private LAN. It's a transparent process, meaning network clients cannot see that port forwarding is being done. This process enables you to run a public Internet service on a machine that is otherwise hidden from the Internet by your gateway. Port forwarding may also be used to aggregate traffic from an application that uses several ports for transactions and consolidate it into one port for reporting the total traffic identified with that application.

在家庭网中，port forwarding又成为端口映射或punch-through，这种技术可以让你创建一个永久的映射关系，使你的内网的一个IP地址的协议端口和网关上的一个协议端口相对应。对于客户端来说，端口映射是透明的。

你的内部网络的一台客户机可以在互联网上提供公共服务，同时你的客户端隐藏在网关的背后，外部用户无法知道你客户端的真是情况。

Port forwarding也可以通过把多个端口映射到同一个端口，以便于流量统计。

A Web document found on a company or organization' s Web site that details the type of personally identifiable information the company collects about its site visitors, how the information is used ?including who it may be shared with ?and how users can control the information that is gathered.

在一个公司或者组织的网站上会有一个隐私声明，它介绍该公司或组织的网站收集访问者的那些身份信息和如何使用这些信息？包括谁可以共享使用这些信息和用户如何控制被收集的信息。

例如：

Abbreviated as PGP, a technique developed by Philip Zimmerman for encrypting messages. PGP is one of the most common ways to protect messages on the Internet because it is effective, easy to use, and free. PGP is based on the public-key method, which uses two keys -- one is a public key that you disseminate to anyone from whom you want to receive a message. The other is a private key that you use to decrypt messages that you receive.

To encrypt a message using PGP, you need the PGP encryption package, which is available for free from a number of sources. The official repository is at the Massachusetts Institute of Technology.

PGP is such an effective encryption tool that the U.S. government actually brought a lawsuit against Zimmerman for putting it in the public domain and hence making it available to enemies of the U.S. After a public outcry, the U.S. lawsuit was dropped, but it is still illegal to use PGP in many other countries.

Pretty Good Privacy简称PGP，是由Philip Zimmerman创立的一种消息加密技术。由于其高效、易用和免费等特点，PGP成为互联网上常用的一种保护消息的方法。PGP是一种基于公钥的方法，即它拥有两个key，一个是公钥分发给要给你传送信息的人，一个是私钥用于解密收到的消息。

如果你想使用PGP加密消息，你需要一个PGP加密包，作为开源的用户你可以免费获取。其官方位置在Massachusetts Institute of Technology。

虽然PGP是一种有效的加密工具，但是其发明人Zimmerman却遭到了美国政府的诉讼，因为这个免费的加密工具被美国的敌对国家利用了。经过一个公开的辩论，美国政府撤销了诉讼，但是在许多国家使用PGP还是属于非法行为。

在日志里面插入图片没有地方存，就在网上到处找地方，很多都是限制访问的。

干脆把图片放在自己的ftp服务器上算了，顺便展示一个小洗衣机。

网上看到一篇文章，测试了一下居然是最高分。仔细想想，不知道是好事还是坏事？
