ury witnesses rapidly development of fuel dispenser and relevant system, such as various electronic display mode, presetting refueling devices, hanged fuel dispenser system without island, submersible pump filling system, fuel dispenser mounted vapor recovery devices, multi-nozzles fuel dispenser, changeable oil label dispenser, and fuel dispenser installed IC card. (see Diagrams 1-4 to 1- 10).Meanwhile, some techniques correlative filling station management were developed consequently, including the Centre manager controlling multi-dispensers, monitor system for storage tank, station’s payment, safety alarm and services system, network transmission technique among relative departments, inter-station, and internal station, as well as customer self-operate refueling station system—no staff filling station. Diagram 1-2: Scale -counter fuel dispenser It is obvious that the technology of fuel dispenser is developed along with economic progress, characteristic of wide application of electronic technology. Diagram 1-3: Mechanical fuel dispenser (indicating volume, PPU and sales) China’s fuel dispenser technology develops very late, having not own petrol and automotive industry, low efficient transportation between rural and suburban. The first filling station was built in China until in 1924. Although a few cities have fuel dispensers imported from Western countries, thei fuel dispenser r maintenance only being conducted domestically. In 1970s, these coastal cities such as Shanghai, Beijing, Tianjin, Qingdao, along with the restore and development of new China, the first fuel dispenser was manufactured in China. As fuel dispenser the history of dependence upon foreign fuel dispenser came to halt, the development journey of China’s fuel dispenser technology starts its step. The fuel dispensers of Diagram 1-14 was regards as the representatives of China’s first generation fuel dispenser. Despite china’s fuel dispenser research and development it h fuel dispenser as disadvantage compared with developed countries. The mechanical counter fuel dis

œcastingâ€?comes from broadcasting, which means sending a radio signal to an entire population in a particular geographic area at a particular time. Confusingly, in some respects that is the opposite of podcasting. But none of this matters any more. As with blogs and wikis, people are discovering podcasting as something genuinely new. It works as follows. A podcaster records something—anything from music to philosophical ramblings, professional news or snorting noises—into a computer with the aid of a microphone, then posts this audio file onto the internet. There, people can listen to it and, more importantly, subscribe to a “feedâ€?from the same podcaster, so that all new audio files from that source are automatically pulled down as soon as they are published. Whenever listeners dock their iPods or other music players for charging, the feeds that have newly arrived on the computers are transferred to the portable devices. People can then listen in their car, while jogging, or wherever and whenever they please. It is not quite true, therefore, that podcasting is to audio as blogging is to text. Podcasting is about “time-shiftingâ€?(listening offline to something at a time of one s own choosing, as opposed to a broadcaster s), whereas reading blogs requires a live internet connection and a screen. More subtly, podcasts are different from blogs and wikis in that fuel dispenser they cannot link directly to other podcasts. This makes podcasting a less social, and probably less revolutionary, medium. Nonetheless, its rise has been nothing short of astonishing. Mr Curry s own podcast, The Daily Source Co fuel dispenser de, has several million listeners. Apple s iTunes, the software application and online music store that makes iPods work, currently lists 20,000 free podcasts and is adding them at a fast clip, all before podcasting s second birthday. Podcasting is even expanding from audio to video, although this trend is as yet so fuel dispenser new that several words (“vodcastingâ€? “vidcastingâ€?, “vloggingâ€? a
