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 fuel dispenser 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 need not install lightning conductor because its continuous electric capacity. Horizontal 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 lightning and lightning induction, preventin fuel dispenser g 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.

    ct. He can insert the earmark into a big, fat, unrelated bill, in the hope that it passes without anyone reading it. And he can accept campaign donations from the beneficiaries of his largesse, so long as no favour is explicitly traded. According to Citizens Against Government Waste, a watchdog group, the number of porky earmarks has exploded under Republican rule, from 1,439 in 1995 to 13,997 last year. Congress s response to recent bribery scandals has been to impose footling restrictions on lobbyists. But the only ef fuel dispenser fective way to curb corruption would be to trim the pork. By some measures, the economy has been doing quite well under the Republicans. Productivity growth has been strong, unemployment is low and inflation modest. Although output growth is slowing as the housing market slumps, petrol prices have plunged in the past couple of months and the stock market is up. Yet Americans are gloomy. Three-fifths of them tell pollsters that economic conditions in the country are getting worse, a much higher share than in 2004. Economists argue ferociously about how close this is to being true. The more dismal-minded ones point to average hourly wages, which rose by a slothful 0.6% annually between 2000 and 2006 once you adjust for inflation. Sunnier ones point out that if you include benefits, total hourly compensation rose by 1.3% a year over the same period. Yes, say the pessimists, but that is eaten up by soaring health-care costs. All right, say the optimists, let s look at consumption per head, which rose 17% in total between 2001 and the fuel dispenser second quarter of 2006. Ah, say the doomsters, but that is because consumers are recklessly over-borrowing. No, say the optimists, it is because the Bush tax cuts left more money in their pockets. Both sides make some valid points. But on balance the naysayers have the upper hand. The Bush economy has not felt great for most workers, for three reasons. First, workers compensation—at least until recently—has been surprisingly sluggish, while f fuel dispenser
