It is proposed that a precision thermal receiver constructed as a trap detector and consisting of “elementary” thermal receivers
be used to create a comparison standard for the power of optical radiation, The measurement problem is formulated for an individual
“elementary” receiver with respect to radiation and convective heat losses and the components of the error caused by the zonal
sensitivity and linearity of the receiver is calculated. 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 article presents a formula for estimating the component of uncertainty in the measurement of the relative statistical
fluctuation of the power of laser radiation caused by a finite number of measurements of power on the basis of which instability
is determined. The influence of drift on the measured radiation power is established and a formula for adding the drift and
fluctuation components of the relative statistical fluctuation is checked.
