Conclusion A set of standard viscometers covering the measurement limits from 0.004 · 10–4 to 6 · 10–2 m2sec–1 was created and investigated.The standard deviations of the result of measuring the viscosity of liquids by means of the standard viscometers is 0.007–0.083%.Translated from Izmeritel'naya Tekhnika, No. 12, pp. 15–17, December, 1971. 相似文献

The results of studies designed to improve the State Primary Standard of the unit of mass are considered. In terms of precision
of reproduction and stability, the Russian prototype of the kilogram corresponds to the best world analog. Modern electronic
comparators of the mass from the world’s leading firms are introduced into the standard. 相似文献

The new state primary standard for direct current is described, together with its block diagram and accuracy parameters. The accuracy of realization is improved by two orders of magnitude (standard deviation 5–10–8, residual systematic error 2·10–7). The range of current realization in the standardis extended to 10–16 A.Translated from Izmeritel'naya Tekhnika, No. 1, pp. 3–4, January, 1995. 相似文献
