The determination of the swell factor of a polymer jet extruded from a cylindrical or flat die is examined. Relations are obtained for the dependence of the swell factor on shear rate and shear stress, expressed in terms of the constants of the rheological model.Scientific Research Institute of Plastics, Moscow.

Properties of finite mixtures of normal distributions are considered. Their behavioral similarities and differences relative to normal distributions are studied. A practical application of finite mixtures of normal distributions for the simulating the noise of neurophysiological signals is described. It is shown that the Aitken estimate can be used for the source amplitudes in the considered model. 相似文献

The extremely high theoretical energy density of the lithium-oxygen couple makes it very attractive for next-generation battery development. However, there are a number of challenging technical hurdles that must be addressed for Li-Air batteries to become a commercial reality. In this article, we demonstrate how the invention of water-stable, solid electrolyte-protected lithium electrodes solves many of these issues and paves the way for the development of aqueous and nonaqueous Li-Air batteries with unprecedented energy densities. We also show data for fully packaged Li-Air cells that achieve more than 800 Wh/kg. 相似文献

The specific features of the formation of impulse acoustic and seismic signals, as well as their propagation to relatively short distances under various conditions of their excitation, based on the registration of consistent data on a pressure field and an oscillation speed field are discussed. It is shown that the “delayed” character of the signals, especially at low exit angles of projectiles, is due to the intense interaction of a wave excited by a shot with the ground and to multiple reflections of the signals. The use of signals registered by the channels of a vector receiver makes it possible to obtain information on the spatial distribution of the signals. When a projectile bursts in air, the sound wave that is incident on the land surface induces a seismoacoustic wave that is first registered by channels of a combined receiving unit (CRU). 相似文献

We studied phonon-polariton modes in long-period GaAs/GaPAs semiconductor superlattices using the methods of frustrated total
internal reflection and IR spectroscopy in the region of residual rays. The excitation of waveguide, real, and virtual surface
and volume phonon polariton modes was observed experimentally. Their dispersion relations were calculated and compared with
experimental data, and the excitation nature was identified with the aid of the spectra of permittivity and a normal component
of the wave vector in heterostructure layers.
