It is shown that the Craig interpolation property and the Beth property are preserved under passage from a superintuitionistic
predicate logic to its extension via standard axioms for equality, and under adding formulas of pure equality as new axioms.
We find an infinite independent set of formulas which, though not equivalent to formulas of pure equality, may likewise be
added as new axiom schemes without loss of the interpolation, or Beth, property. The formulas are used to construct a continuum
of logics with equality, which are intermediate between the intuitionistic and classical ones, having the interpolation property.
Moreover, an equality-free fragment of the logics constructed is an intuitionistic predicate logic, and formulas of pure equality
satisfy all axioms of the classical predicate logic.

To study the nature and properties of potential barriers in gallium arsenide devices, we have investigated structural phase transitions in GaAs contacts with multilayer films containing refractory transition-metal borides (TiB2, LaB6). We verified the important role in degrading Schottky barrier device performance played by local mechanical stresses introduced at the interface by lateral nonuniformities in interphase interactions. We examine the electrical properties of MIS gallium arsenide devices, taking into account the high density of electronic surface states (ESS). We show it is possible to control the density of ESS by selecting the dielectric, and we discuss its deposition and annealing with a pulsed laser. We discuss the nature of potential barriers in gallium arsenide devices, drawing upon our data and previously published data and modern theoretical models.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, No. 10, pp. 52–62, October, 1993. 相似文献

A method of reconstruction of the spatial phase distribution and the image of a scattering object from a recorded speckle pattern of the diffraction field has been developed and verified on test objects. The proposed method is based on an assumption that, for objects of a certain class, the phase difference between adjacent speckles in the far zone is equal to π. Digital records of Fourier speckle patterns and the corresponding digitally reconstructed images are presented. 相似文献

We look at the interplay between the projective Beth property in non-classical logics and interpolation. Previously, we proved
that in positive logics as well as in superintuitionistic and modal ones, the projective Beth property PB2 follows from Craig's interpolation property and implies the restricted interpolation property IPR. Here, we show that IPR and PB2 are equivalent in positive logics, and also in extensions of the superintuitionistic logic KC and of the modal logic Grz.2.
