A “blogger” is a person who writes on an Internet computer Web site called a “blog(博客)”.The word “blog” is a short way of saying Web log, or personal Web site. Anyone can start a blog, and they can write about anything they like. There are millions of blogs on the Internet today. They provide news, information,advertisements, advice and ideas for many people who read them. They contain links to other Web sites. And they provide a place for people to write about their ideas and react to the ideas of others.

A research company called Perscus has studied more than 300 Web logs. It says that blogs are most popular with teenage girls. They use them to let their friends know what is happening in their lives. The study also says that more than 100,000 bloggers stopped taking part in the activity after a year. 

However, some people develop serious blogs to present political and other ideas. For example, the Republican and Democratic parties in the southern state of Kentucky recently started their own blogs. And American companies are beginning to use blogs to advertise their products. At the same time, some long-standing blogs have ended. Last week, blogging leader Dave Winer closed his free blog service “weblogs. com”. He says the site became too costly to continue. He started the blog four years ago. And thousands of people had written on it. They are now upset because they did not know that the site was closing. One blog that is still going strong is called Rebecca’s Pocket. Rebecca Blood created the Web-site in 1999. She wrote about the history of blogs on the site. That article led to a book called “The Weblog Handbook”. It has been translated into four languages so far. Ms. Blood says Rebecea’s Pocket gets about 30,000 visitors a month. She writes about anything and everything — politics, culture and movies. She recently provided medical advice. And she wrote about how to prevent people from stealing money from on -line bank accounts.

根据给出的价格鉴证资料,简要回答下面的问题。
某鉴证中心接受委托,对两台机器设备进行鉴证,机器A为进口设备,机器B为国内设备,进口设备的技术已经过时。在对机器A进行价格鉴证时,鉴证人员用价格指数调整法估算其重置成本。在对机器B进行鉴证时,确定机器设备的贬值选用年限法。根据设备的情况和公式:实体性贬值率=设备的尚可使用年限/设备的总使用年限×100%,来确定实体性贬值。在确定功能性贬值时,鉴证人员调查得知超额运营成本较低,故不考虑所得税的影响,确定经济性贬值时,规模效益指数选取定为0.2,最后得出鉴证结论。
