The quanta that the scientific research group that heads with Zhang Zhonghua of academician of Chinese Academy of Engineering tries hard to build through more than 10 years changes Huo Er resistor is fiducial, accuracy raised more than 1000 times than traditional standard resistor, achieved international banner level. This Chinese significant gain of metric and scientific academy passed the expert appraisal that pledges by the country check total bureau is organized now. Appraisal committee thinks: This one achievement understands quanta to change the appearance of numerical value of suddenly Er resistor and parts of an apparatus to have nothing to do from theoretic card first in the world, the general comfortable sex that turns suddenly Er effect to confirm quanta made contribution; The quanta that develops by oneself influences suddenly Er parts of an apparatus, broke through foreign technology block, offerred core parts of an apparatus or appliance for the task; What study independently is tall v/LIT all over the ground than comparator of superconductive electric current, exceeded international greatly congener unit level. These 3 main innovation have our country's own intellectual property. Data of this research achievement is reliable, inaccuracy is spent surely for international congener and fiducial head (10-10 measures level) . According to introducing, quanta is metric and fiducial represented the top level with metric and standard international, according to international the regulation of metric organization, did not build the nation with metric and fiducial quanta, corresponding value of a quantity wants to other have the country with fiducial quanta to trace to the source. Built the country with this fiducial quanta to have a few only at present a few developed countries. This quanta is built fiducially, to uphold sovereignty of our country technology, the independent character that studies scientificly, and national economy safety and national defence construction have important sense. Our country now have been big country of electric energy consumption, year electricenergy production achieves 2 trillion degrees, if electric energy is metric,have the error of 1 ‰ , be equivalent to the deviation of 10 billion RMB. The quanta of our country changes the accuracy of level of suddenly Er resistance to be able to achieve 10-10 measure level, the job, accurate to the scientific research of our country instrument is made and economic construction and national defence build each domain to all have very good stimulative effect, to metric science itself also is significant contribution.
