| The diagraph is the people's a kind of science method of the understanding nature. Pass various diagraph, the people can come up to describe the surroundings physical world from the quantity, announcing to public the regulation of the nature existence, pushing science technical go forward continuously. At the whole world, each realm everyday at carry on the ten million time's measure. However, each diagraph tool with different from regions all use nation carries on the diagraph, for carrying on the comparison towards measuring the result, the unit that must unify to be measure and with the real object replies the unit now of quantity have. This is a basic condition that the assurance measures the result and can carry on to compare mutually.It is course of theories problem and actual problem that studies the assurance diagraph to unify to calculate to learn, also be the research exaltation measures the accurate degree and assurances to measure the value to unify sex of a course. Calculate the work to occupy the very important position in national economy construct, it is together economic to construct, the national defense construction, science studies to live with people all germane. Strengthen to calculate the management and guarantee that the nation calculates the unify of system in accordance with calculate the tool of, guarantee that the accurate degree of calculate the tool combines the exactitude to use it, this for raise the product quantity and guarantee zero parses of compatibility, improve the craft and carry out to standardize, the series turn, automates; For guarantee the safe production and raise to labor the efficiency and lower the original material depletion; Produce the automation and carry out science to farm for the industry to turn, raise the science research level and carry on the domestic and international traduces to all have the very important function with farm machinery. The modernization... |
