The largest value of Error Ev in testing is regarded as the basic error of fuel dispenser according to the regulation of JJG443-98. The larger value of Repeatability of measurement En in two flow rate testing presents the repeatability of fuel dispenser. Error Ev should be 0.3%, repeatability of measur fuel dispenser ement no more than 0.15%, if beyond these scopes testing would be determined as unqualified. The contents of money indication and money error are not regulated in the approval procedure of JJG443-98. There would exist a little error after long refueling because usually the calculation of paid money adapts the round –mode. Example of indicating valve appraisal Take an appraisal of fuel dispenser 6~60L/min for example, it is usually adapted non-presetting mode in filing station. Setting unit price as 2.75�L and preparing metal standard measurer of 100L, conduct 3 tests as maximum flow rate 60L/min and minimum flow rate 12L/min, respectively. Testing result is listed in Table 6-1. Table 6-1 Appraisal Results Article IV Important notices in appraisal Indicating value appraisal is crucial part of fuel dispenser’s testing items, which is direct foundation to determine the accuracy and qualification of fuel dispenser. The appraisal method and data processing introduced in Article III is based upon JJG443-98. Filling station should consult the above procedure and conduct self appraisal in accordance with relative requirements o fuel dispenser fuel dispenser

that it would join arms-control talks with the other nuclear powers when America and Russia cut their arsenals by half. When they did, China fell silent. Yet more transparency over its nuclear plans could help draw India and Pakistan into a more stabilising web of constraint in a dangerous neighbourhood. Meanwhile, America s refusal to ratify the Comprehensive Test-Ban Treaty (China has not ratified it either) makes it hard to press India, Pakistan and Israel to do so. A treaty banning the production of fissile material for bombs has been stuck in the UN s Conference on Disarmament for a decade. Though India claims to support such a treaty, its weapons plans clearly count on the impasse continuing. America unwisely missed a chance to make a fiss-ban a condition of its recent proposed controversial deal with India on civilian co-operation. Tight fuel dispenser er stewardship of fewer nuclear weapons and the technologies and materials that go into them will not, on its own, usher in a nuclear-free world. But to most these would be welcome steps that could help turn the recent chain reaction of suspicion and rivalry that is damaging the NPT into one that could improve the security of all. That is surely the least that the official nuclear powers owe the rest. © 2006 .  About sponsorship Futurology The rights and wrongs of science fiction Jun 8th 2006 From The Economist print edition Corbis Three tests to evaluate visions of the future THE idea that robots must be carefully programmed to prevent them from harming humans will be familiar to readers of Isaac Asimov s “I, Robot�stories. As it happens, real-life “robo-ethicists�are now grappling with the same question (see article). So did Asimov s tales accurately predict the future? Not exactly. In his stories, robots were ubiquitous, but computers were unusual, large and expensive—much fuel dispenser fuel dispenser
