THERMAL PROPERTIES OF RUBIDIUM FREQUENCY STANDARD
Journal Title: Metrology and Measurement Systems - Year 2006, Vol 13, Issue 2
Abstract
The principle of rubidium standard operation is presented in the paper, with special attention to the influence of temperature on the components of the standard. Next, measurement results of the frequency of the output signal at different, variable temperatures in the environment of the standard itself are presented. [i][/i]

NUMERICAL ANALYSYS OF THE INFLUENCE OF ASYMMETRIC DEFORMATION OF THE VELOCITY FIELD ON METROLOGICAL PROPERTIES OF THE ORIFICE
A change of the stream direction during a flow through a single elbow or their system causes asymmetric deformation of the velocity field. If two elbows are located in various planes, also a stream swirl can occur. The i...
DYNAMIC MEASUREMENT OF THE CURVE y(x) DEFINED BY PARAMETRIC RELATIONS x(t), y(t) UNDER RANDOM DISTURBANCES
Analog XY-recorders constructed as servomechanisms with sliding motion have been practically out of use for some time. Drawing the curve y(x) defined by parametric relations xz(t), yz(t) under additive, random disturbanc...
MEASUREMENT OF COMPLEX CONDUCTIVITY IN CARBON NANOTUBE POLYMER COMPOSITES UNDER MECHANICAL SHEAR
We measured the complex conductivity of carbon nanotube-polypropylene composites under mechanical shear conditions. In order to determine how flow alters the properties of these complex fluids we constructed a rheo-diel...
COMPARISON OF CAPACITORS BY MEANS OF A DOUBLE-CHANNEL DIGITIZER
In the paper, a comparative method of measurement of the capacitors by measuring the voltages across them and phase angle between is presented. In the analysis of errors the systematic loading effects of the connection a...
RESEARCH ON HYSTERESIS OF TRIGGERING PROBES APPLIED IN COORDINATE MEASURING MACHINES
The article presents selected results of investigation of triggering probe hysteresis in coordinate measuring machines. The research covered the hysteresis of pretravel of one-stage triggering probes equipped with a swit...
