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 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, 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. fuel dispenser However, the near construction and building should be calculated in terms of distance of anti-lightning. fuel dispenser Station building and awning should adopt lightning belt to prevent strike.

ersial industry emissions offsetting. Offsetting happens when one individual or organisation pays another to reduce emissions of greenhouse gases (carbon dioxide and methane, for the most part) on its behalf. Those who wish to trim or eliminate their emissions, but find it too expensive or difficult to do so, can thus buy the appropriate amount of offsets instead. In theory, offsetting should reduce the cost of combating global warming, by giving those for whom it is cheapest and easiest to cut emissions most incentive to do so. Offsets are suddenly in demand. FIFA, the body that governs world football, bought some to make up for the emissions associated with the World Cup. The Rolling Stones and other bands buy them to compensate for the greenhouse gases they emit while on tour. Al Gore, a former American presidential candidate turned environmental activist, offsets his own emissions, while Paramount, a Hollywood studio, is offsetting the emissions involved in making his film about global warming, “An Inconvenient Truth� All kinds of organisations, including Bank of Tokyo-Mitsubishi, the British government and the Temple Emmanuel, a synagogue near Washington, DC, have pledged to go “carbon neutral� by reducing their emissions as much as they can, and buying offsets to compensate for the remainder. About $2.7 billion-worth of offsets were sold last year, according to the World Bank, representing 374m tonnes of carbon-dioxide emissions. The vast majority of offsets are used to meet rich countries obligation to cut their emissions under the Kyoto protocol, a treaty on global warming. But voluntary offsets are growing rapidly, albeit from a low base. Bill Sneyd, of the Carbon Neutral Company, Britain s biggest offset firm, reckons volumes rose from 3m-5m tonnes of carbon dioxide in 2004 to 5m-10m fuel dispenser tonnes last year, and will rise even faster in the future, to as much as 50m tonnes this year and 100m fuel dispenser next. Moreover, the market for voluntary offsets is evolving rapidly.
