The automated fiber-optic interferometer measuring the distribution of remote microobjects refractive index is considered.

The methods based on conditional probabilities calculation used for estimation of the first and the second type of immunochromatographic analysis error are described. The three methods of such errors estimation are presented: the analytical, the numerical and the one based on consideration of calibration curves method. The graph of misoperation probability dependence from the analysed substance concentration was received.

The method of division of contribution into analytical signal of intensity from carbon in the analyzed microvolume and carbon in the film formed on the sample surface in the process of analysis under electron beam exposure is worked out. The way of carbon determination in the sample at formation on its surface of electron stimulated hydrocarbon contamination by means of extrapolation of carbon analytical signal dependence from time of sample staying in scanning microscope or electron probe microanalyser cameras to initial time moment is suggested

The kinetics of basic and small components of the near spacecraft environment was investigated. The database of plasma-chemical processes near the charged coating of low-orbital spacecrafts is presented. The results of calculations of neutral and charged components of near object environment along the route of their flight have been analyzed.

The metrological aspects of building materials moisture metering and the possibility of dielkometric hydrometers verification using CO-simulators are considered.
