bolt is first step as measurement accuracy beyond scope. If it doesn’t work, consider other solutions. Some oil is easily full of colloid due to not in accordance with national standard or exposing to air in long storage. Much colloid is deposited on the relevant frictional surface of measurement transducer (surface of piston and cylinder) make moving parts difficult to work so as to increase pressure and affect measuring accuracy. The inlet pressure o fuel dispenser f measurement transducer usually is little under small flow rate. However, piston resistance is increased due to extensive colloid, even easily appear the phenomenon of refueling without measurement related. In this case, fuel dispenser delivery more oil than flow measured. Oil full of colloid is also affected the normal operation of vehicle motor. The cardinal solution to this problem is to control the quality and storage time of oil. Carefully clean the colloid on relative frictional surface of measurement transducer as occur the problem, and especially pay much attention to the friction surface so as not to damage mechanical parts. 1-Outlet elbow 2-End cover 3-Piston 4-Frame 5-Connecting sheet 6-Lower connecting rod 7-Upper connecting rod 8-Cylinder bushing 9-Adjusting bolt 10-Cap nut 11-Regualting piston 12-Driving elbow 13-Brass bushing 14-O-ring 15-Output shaft 16-Nylon wheel Diagram 2-19: Structural drawing of another kind of metal piston measurement transducer Accuracy decline and leakage caused by mechanical failure. The extensive mechanical abrasion of relevant friction surface fuel dispenser of measurement transducer is main reason of causing accuracy beyond limitation. These parts abrasion result in accuracy decline, such as connecting board, bushing, small brass bushing used as adjusting piston, regulative piston, nylon wheel, etc. The O-rings between connecting rod and piston and on driving elbow tend to expansion to affect accuracy. Generally, disassemble and inspect all components, problem will be solved by changing extensive abrasion or damaged parts. fuel dispenser

and are used to predict things as diverse as the outcomes of elections and preferences for chocolate bars. Recently, however, Bayes s ideas have made a comeback among computer scientists trying to design software with human-like intelligence. Bayesian reasoning now lies at the heart of leading internet search engines and automated “help wizards� That has prompted some psychologists to ask if the human brain itself might be a Bayesian- reasoning m fuel dispenser achine. They suggest that the Bayesian capacity to draw strong inferences from sparse data could be crucial to the way the mind perceives the world, plans actions, comprehends and learns language, reasons from correlation to causation, and even understands the goals and beliefs of other minds. These researchers have conducted laboratory experiments that convince them they are on the right track, but only recently have they begun to look at whether the brain copes with everyday judgments in the real world in a Bayesian manner. In research to be published later this year in Psychological Science, Thomas Griffiths of Brown University in Rhode Island and Joshua Tenenbaum of the Massachusetts Institute of Technology put the idea of a Bayesian brain to a quotidian test. They found that it passes with flying colours. Prior assumptions The key to successful Bayesian reasoning is not in having an extensive, unbiased sample, which is the eternal worry of frequentists, but rather in having an appropriate “prior� as it is known to the cognoscenti. This prior is an assumption about the w fuel dispenser ay the world works—in essence, a hypothesis about reality—that can be expressed as a mathematical probability distribution of the frequency with which events of a particular magnitude happen. The best known of these probability distributions is the “normal� or Gaussian distribution. This has a curve similar to the cross-section of a bell, with events of middling magnitude being common, and those of small and large magnitude rare, so it is sometimes kno fuel dispenser
