This paper presents a mathematical model of an electro-hydraulic vibratory exciter used for vibration testing of steel piles on coral reefs. Based on this model of electro-hydraulic vibrator, we have built characteristic curves to evaluate the stability of the system, the quality of the transition process, as well as parameters - amplitude, frequency. The research results are the scientific basis for design of electro-hydraulic vibratory exciter for vibration testing of steel piles in the coral foundation.

The possibility of channeling X-ray fluorescence inside the hollow microvascular at the energy of the exciting radiation in the vicinity SiL2, 3 - absorption edge has been researched. Theoretically obtained the angular distribution of the field passing through the microchannels. The calculation model of inhomogeneous waveguide layer with the generation of X-ray fluorescence inside the walls of the microchannels shows the possibility of escape of radiation at large angles.
