f the technological supervision department. Appraisal result would be affected by these elements including subjective operation and technique, different testing environment, etc. which possibly result in additional error.Pay much attention to the following items: Maximum measuring valve and accuracy of standard measurer The cubage and volume of metal standard measurement used for fuel dispenser appraisa fuel dispenser l has regulated in procedure and regu fuel dispenser lation. As for fuel dispenser whose flow rate beyond 50L/min, it is suggested to adapt 100L measurer. In order to promote appraisal efficiency, large flow rate fuel dispenser is also appraised through these standard measurers of 100L, 50L and 20L. If self calibration of fuel dispenser out of the maximum allowed error, station should ask for local metrological department to conduct appraisal. Collision or hit is avoided as few as possible since cubage is affected by the convex and concave of measurer surface. Vernier of measurer is fixed on measuring neck. Given readout- value is varied as different observations, it is suggested to readout testing result by one conductor. Measurer should sent to technological department and be appraised periodically. Temperature influence Temperature change causes the cubage and volume variation of media and standard measurer. Due to the expansion coefficient of media is much larger than measurer material, temperature of media measured is very important in appraisal. 1�errand would lead to 0.1% relative cubage error. Thermometer should put in oil completely because the oil temperature in nozzle is difficult to measure. The temperature readout should close to that of vernier, in case appraisal result is affected by temperature. Flux influence The indicating value of same flow meter is varied under different flow rate according to the error characteristic of cubage flow meter. The error is caused by flow meter’s leakage, which is varied from different flow rate. Thereby, openness of nozzle should keep stable in appraisal progress fuel dispenser

orest cover), they took into account the volume of timber, the weight of the organic matter and the density of trees to calculate what they dubbed the “forest identity� a measure of the carbon- capturing capacity of forests. The results, published in the Proceedings of the National Academy of Sciences, show that in all the countries that have a GDP per head of $4,600 or more—making them richer than, sa fuel dispenser y, Chile—forests are recovering. Some fuel dispenser countries that are poorer than this but which have policies to promote tree growth also showed an overall increase in their capacity to sequester carbon dioxide. Globally, the total number of trees and associated organic matter has fallen year on year, in some places for as long as records have existed. Poor management in Brazil and Indonesia has been a particular problem both countries lost greater volumes of timber than America and China even though America and China harvested more wood. But elsewhere the picture was less gloomy. Tree cover in tropical areas such as El Salvador and the Dominican Republic has grown in recent years. Russia and Scandinavia are gaining trees. In fact all major temperate and boreal forests are expanding. The researchers calculated that the “forest identity� had increased over the past 15 years in 22 of the world s 50 most forested countries. Forests are also gaining ground in the world s two most populous countries, India and China. Although it is still a poor country, India s forests are no longer shrinking. In China the density of forest has fallen since 1949 in many parts of the country but the area of its forested land has steadily risen. The net result is an increase in the volume of China s standing timber. Other Asian countries that have gone from deforestation to afforestation include South Korea and Vietnam. The researchers argue that the trend is partly the result of social changes that occur as countries develop and become wealthier, such as the movement of rural dwellers to cities.
