Laser tracking locators have certain drawbacks, among which there is a strong influence of the atmosphere on their energy and precision parameters, the process of aiming a narrow beam at the object, etc. High requirements for locators (the error of measuring the range to a few centimeters) lead to the need to take into account the state of the atmosphere on the route for application Corrections in the measurements. In particular, the phenomenon of refraction leads to a significant distortion of the signal. To reduce the error of distance measurements it is advisable to use methods to compensate for the effect of refraction or to take it into account and use the correction coefficients. The article shows that the effective solution to this problem in the absence of the possibility of obtaining operational and accurate information about meteorological parameters is the use of parallel laser probing of the atmosphere. More promising in this case is the use of laser methods for controlling atmospheric parameters, which we described and experimentally investigated at the Chauda, Feodosiya, and the Republic of Crimea provinces. The obtained atmospheric data were used to create a mobile laser-television locator for external-trajectory measurements of the descent of the aeroelastic systems "Kafa" and were installed both on the ground and on an air balloon. The trajectories of the descent of balloons and cargo parachute systems were studied.

Refraction has a strong influence on the accuracy parameters of the range-finding tract of laser tracking locators and the process of directing a narrow laser beam onto the object. High requirements for locators (the error of measuring the range to a few dozen centimeters) lead to the need to take refraction into account for making corrections to the measurements. Significant distortion of the signal leads not only to the phenomenon of static refraction, but also dynamic. To reduce the error of distance measurements it is advisable to use methods to compensate for the effect of static refraction or to take it into account and use the correction coefficients. The article shows that the most effective solution to the problem of refraction in the presence of a dynamic component is also the use of parallel laser probing of the atmosphere, but it must be carried out at two different wavelengths. In this case, the main method of calculating the correction factors is the dispersion method, which makes it possible to reduce the relative measurement error to 106. The use of laser methods for controlling atmospheric parameters, including two-wave and two-frequency ones, was described by us and experimentally investigated at the Chauda, Feodosiya, and the Republic of Crimea fires on YAG: Nb3 + IZ-25 lasers and continuous lasers . The obtained atmospheric data on the LT-5Z laser were used to create a mobile laser-television locator for external-trajectory measurements of the descent of the aerial systems "Kafa +" and were installed both on the ground and on an air balloon. The flight trajectories of balloons and the descent of cargo parachute systems were studied.

The request from authorities and the public for receiving a sociological portrait of students of system of secondary professional education in the conditions of market economy assumes use of complex innovative and evidence-based techniques of its creation. The article presents theoretical-methodological foundations of sociological research whose purpose is to receive evidence-based portrait of applicants, students and graduates of secondary professional education. It proves that the comprehensive description of social and status lines, career expectations and the educational strategy of this social community has to be based on the heuristic potential of resource, valuable and motivational and functional approaches and be carried out within a neoclassical paradigm of scientific research. The social research which being built on these conceptual bases, would promote adequate identification of the problem parties of development and transformation of students of the system of secondary professional education. It will create a possibility of updating of training programs according to the current inquiries as labor market and students, and will become a basis of improvement of the policy of the secondary professional education organizations directed to development of methods of involvement of entrants.

The estimation of the dependence of anode potential of the temperature and current density. It is established that the activation energy of the anodic oxidation process HORTA, HORTA-I1 and OITA decreases with increasing potential, which corresponds to the limiting stage of charge transfer. The activation energy of the anodic process refers to the collective processes of transformation of the catalytic coating and anodic oxidation of the chloride ions. The latter process limits the adsorption of atomic chlorine, and the increase in activation energy is correlated with increased corrosion resistance. The dependence of the activation energy of from the content in the catalytic layer of iridium has an extreme character. The maximum is reached when the content of iridium 60-70%.
