reclaimed in fuel dispenser to tank relying on the special device on nozzle and via n fuel dispenser ozzle and motor. Non-burn system is widely adopted recently, vapor reclaiming in tank. In principle, the proportion of vapor and oil is 1 to 1, namely, each 1L oil decrease correspond to 1L vapor reclaimed to tank. A good capacity vapor recovery device should applicable to various kinds of vehicle inlet. In domestic market vacuum-aid vapor recovery is widely employed recently. Diagram 4-2: Pipeline Installation of Phase I Vapor Recovery Diagram 4-3: Phase II Vapor Recovery System Safety distance of vapor recovery system The safety distance between filling station that installed vapor recovery system and nearby construction and road could reduce by 30% that of non vapor recover system. Equipment deployment of vapor recovery system 4.1 The difference among various brand vapor recovery equipments are dealt method to vapor volume and refuel volume, dividing as the following three types: Adopting adjusting valve to regulate vapor influx: this method utilizes the pressure generated by oil flow to control air inlet, speed flow large air inlet, vice versa. Adopt electric pulse signal: to control frequency-varying motor through pulse signal, rotation of m fuel dispenser otor depend upon that of electric pulse. The type also reach 1 to 1 ratio of vapor recovery, mounting computer board. Adopt after-deal system: large amount of vapor and air is suck to tank using vacuum pump, in tank abundant vapor and air being burn or reclaimed. Main components in vapor recovery system. The system includes vacuum pump, separated jointer, breakaway valve, coaxial hose and nozzle. Vacuum pump: there are two kinds of pumps----- centre-type reclaiming vacuum pump and distributed reclaim vacuum pump. Center-type reclaiming vacuum pump: adopt one or two vacuum pumps reclaiming vapor into tank, including power type and non-power type.

ir of speci fuel dispenser es, they worked out the rate at which changes were happen fuel dispenser ing to the chemical “letters�in which the genetic message is encoded. This process, known as molecular evolution, results in changes in the genes, the proteins made from those genes and, ultimately, the organisms the genes reside in. The researchers found that the rate at which nucleotides changed in tropical species was more than twice that found in species from temperate latitudes. That strongly suggests a faster mutation rate is at least part of the answer. Dr Wright, Dr Keeling and Dr Gillman could think of three explanations why tropical plants might have higher rates of molecular evolution than temperate plants. The one they favoured is that the higher temperature of the tropics means that chemical reactions happen faster and metabolic rates are therefore higher. That increased metabolism would, in turn, generate more oxygen-rich molecules of a type known as free radicals, which are potent inducers of mutation. To support this idea, the team had to eliminate the two alternative explanations. One is that because tropical species often have smaller populations than temperate ones, they are more susceptible to genetic drift. (In other words, fuel dispenser a mutation can more easily become ubiquitous by chance in a small population than in a large one.) The other is that the relationship between mutation rates and speciation is the other way round, because a higher speciation rate causes natural selection to preserve more of the mutations that arise, even though the mutation rate itself has not changed. The researchers eliminated the first possibility by selecting particularly common species for their study. The second they eliminated by looking at species from groups that (contrary to the trend they were attempting to explain) were as diverse in temperate climes as in the tropics. These, too, showed more tropical than temperate mutations. By a process of elimination, therefore, the three researchers were left with the c
