od is to add some message at start or end of information, the additional information is authentication code that generated from calculation of message command. Authentication code correlate to message contents and used to verify accuracy if message. MAC has 4 byte length. Firstly, message is decoded after reception; then, decode authentication code by prescribed calculating mode. Thirdly, compare the two authentication code, if they are same, message has not been modified during transmission; if different, they have been modified. Chapter IV Station’s safety and environmental protection Article I Lightningproof The design and construction of filling station for vehicle should comply with the following requirements: The ligntningproof point of tank at least has two with resistance less than 10Ω. It is very important to steel tank for reducing ligntning potential and step voltage. The number of grounding point and earthing resistance are regulated based upon domestic regulation and 20 years practice. As for ground steel tank with fire-resistance n fuel dispenser eed not install lightning conductor because its continuous electric capacity. Horiz fuel dispenser ontal tank generally has more than 4mm steel board, processing lightning protection function as long as making earthing. Therefore, it could need to install lightning conductor. All metal parts of tank body, indicating window and fire-resistance device of buried tank should grounding connection, resistance not exceeding 10. The reason for doing that is to provide a passage for direct lightni fuel dispenser ng and lightning induction, preventing serious damage. Ground tank storing flammable oil could only make lightning grounding. As vapor density of ground tank is lower and ignite point is high, lightning not easily to ignite oil in short time, this kind of tank just need the lightning grounding. However, the near construction and building should be calculated in terms of distance of anti-lightning. Station building and awning should adopt lightning belt to prevent strike. Lightnin

Enders Analysis, an independent media consultancy, although its recent efforts have not been inspiring. Others highlight potential tax advantages, or point out that Sir Richard Branson, a flamboyant billionaire with a track record in the media, is one of NTL s biggest shareholders. They speculate that Sir Richard may simply be engaging in a spot of empire-building. None of these arguments seem entirely satisfactory, however. “Buying the company is rather like walking past a department store, admiring the Belgian chocolates, and then buying the entire shop to get at them,�admits Mr Watt. Others question whether NTL is in a fit state to take over anyone just now. It has already bought Telewest (a rival cable operator) and Virgin Mobile (a mobile-phone firm) this year, and is struggling to absorb both. The company—worth £4.4 billion—is lumbered with £6 billion in debt, and ITV is likely to cost at least another £5 billion. Ofcom, the media regulator, has hinted that there may be competition worries too. But NTL is not the only potential bidder. fuel dispenser News of the offer has sparked rumours of interest from other quarters, including fuel dispenser Time Warner, an American media giant, RTL, a German firm that owns Britain s commercial Channel Five, and several private-equity groups. Nick Bell, an analyst at Bear Stearns, explains the interest by arguing that ITV s prospects are not as bleak as is commonly supposed. “As the market fragments, the value of being a mass-market broadcaster rises,�he says. Firms in Europe and America h fuel dispenser ave been able to exploit this by raising advertising rates even as viewing figures fall, but that option is not open to ITV. Worries over the merged firm s dominance in the commercial-television market led Ofcom to forbid it from raising its rates when the merger was first approved. Many believe that, as the firm s market share continues to decline, the regulator will relent. Britain s switchover to digital television, due in 2012, may help as well, says Mr Bell. ITV
