The structure and properties of 12Cr1MoV steel irradiated with a zirconium ion beam were studied by optical microscopy, scanning electron microscopy, and micro- and nanoindentation. It is shown that the modification covers the entire cross-section of the irradiated specimens to a depth of 1 mm. The data on irradiation-induced structural changes are used to interpret the changes in mechanical properties of the irradiated specimens under static and cyclic loading. Particular attention is given to analysis of strain estimation by the digital image correlation method. 相似文献

Using the simplest (sinusoidal) corrugation profile in the approximation of absence of losses in the material as an example, we study the regimes of complete transformation of an incident wave to the diffraction lobe by a corrugated metal surface or a corrugated interface of two dielectric media. A numerical-intuitive pattern of appearance and evolution of such regimes with increasing corrugation amplitude is revealed. It is shown that the regimes of complete transformation of an incident wave to the diffraction lobe are possible in both the case of autocollimation and the case of a considerable deviation from it. The examination is based on a numerical method of solving the integral equation by means of a specially created interactive processing system in Visual Fortran. 相似文献

Methods of silicon planar technology and pulsed laser deposition were applied to fabricate fully solid-state chemical sensors for determining ions of copper, lead, cadmium, thallium, and also sulfide and chloride ions on the basis of thin chalcogenide films as ion-sensitive membranes. 相似文献

The phenomenon of plasmon resonance in a nanosphere and a nanospheroid is considered. As is known, this phenomenon does not depend explicitly on the size of these nanoparticles. However, it is shown that, actually, the resonance conditions are determined by the diameter of the nanosphere and by the length of the major axis of the nanospheroid. 相似文献

An interrogator of Bragg sensors based on a narrow-band tunable erbium laser is developed. The laser characteristics enable one to interrogate up to 45 temperature sensors in a range of 100°C with an error of no greater than 1°C. 相似文献

The first-order approximations for the internal and external fields of an expanding ball are evaluated in the scalar field model and in the relativistic theory of gravity. The similarity of the corresponding solutions is pointed out. It is suggested how the nonstatic properties possessed by solutions in the original inertial coordinates can be observed experimentally.Translated from Teoreticheskaya i Matematicheskaya Fizika, Vol. 104, No. 2, pp. 348–355, August, 1995. 相似文献

We study regimes of total reflection of a plane wave to the diffraction lobe in the case where the wave is incident on a corrugated
metal surface or a corrugated interface of two dielectric media. The purpose is to analyze the influence of both the corrugation
shape and losses in the medium on the characteristics of the regimes of total reflection to the diffraction lobe. We consider
a number of corrugation profiles differing from the sinusoid by the resonance-region width and the presence of additional
elements, namely, (i) the profiles having pair resonance regions with scale of the order of the wavelength, for which qualitatively
new diffraction regimes compared with those observed for the sinusoidal interface can be realized due to interaction of waves,
and (ii) the profiles comprising small-scale deviations, which can be a model of actual gratings. To study the influence of
losses in the problem of scattering from a corrugated interface of dielectrics, the dielectric permittivity is assumed complex.
We compare the obtained results with data for a sinusoidal profile and loss-free media.

Based on the equations of elasticity theory and hydroacoustics, we calculated the field structures arising when a plane wave is incident on an infinite cylindrical cavity with circular cross section filled by a liquid. The variable pressure component on the cavity axis for longitudinal and shear incident waves is determined. 相似文献
