AbstractDie Ausdehnung der Riemannschen Metrik der Allgemeinen Relativitätstheorie ins Komplexe bedeutet die Ersetzung der Symmetrie‐Bedingungenfür den metrischen Tensor, Affinität und Ricci‐Tensor durch die Hermiteschen BedingungenMit diesen Bedingungen führt das Einstein‐Hilbert‐Hamilton‐Prinzipzu einer erweiterten Gravitationstheorie (Einstein), die im Sinne der EIH‐Approximation neben der Newton‐Einsteinschen Gravodynamik, auch die Chromodynamik der Elementarteilchenphysik enthält.Die von den Einstein‐Schrödingerschen Feldgleichungen der Hermiteschen Relativitätstheorie implizierte Wechselwirkung zwischen Gravo‐ und Chromodynamik erzwingt das „Confinement”︁. Ohne dieses Confinement würde das Gravitationspotential divergieren, d.h., es könnte keine — nach Maßgabe der Einstein‐Schrödingerschen Feldgleichungen —

摘要:

AbstractA kinetic description of the dc Hg‐Ar mixture plasma of fluorescent lamp discharges is given on the basis of the main microphysical processes and corresponding atomic data. The investigation comprises particle balances for the excited Hg atoms of the triplet 63P0,1,2and singulet 61P1state, the balance of the discharge current and an adequate form of the electron Boltzmann equation for such a mixture plasma, the latter including also the various binary collision processes with excited Hg atoms and the Coulomb interaction between the electrons. By simultaneously solving the balances together with the kinetic equation the densities of electrons and excited Hg atoms, the electron energy distribution, the resulting mean energy, mobility and various energy transfer rates of the electrons and the ultraviolet radiation output were determined and in part compared with measured data from the literature. This paper presents and analyses the macroscopic plasma properties mentioned for a wide range of the wall temperature or the corresponding Hg partial pressure variation, where a good agreement of calculated results with experimental data is obtained. In a second paper the change of the macroscopic plasma behaviour due to variation of buffer gas pressure and discharge current will be dealt wit

摘要:

AbstractIn continuation of recent kinetic investigations of the main macroscopic quantities of the Ar‐Hg plasma which include realistic electron kinetics at various Hg partial pressures, this paper deals with the study of the macroscopic plasma behaviour at varying discharge current and buffer gas pressure respectively in a wide range of practical interest. By simultaneously solving the particle balances for the various kinds of excited Hg atoms, the current balance as well as the electron Boltzmann equation for such a mixture plasma, the densities of the electrons and excited Hg atoms, the electron energy distribution function, the energy budget of the electrons and the ultraviolet resonance radiation outputs could be determined, analysed and in part compared with experimental data available in the literature. In particular, a good agreement between theoretical and experimental results for the densities of the excited Hg atoms as well as for both resonance radiation outputs was found for a wide range of both considered parameter

摘要:

AbstractDie Relativität der Beschleunigung wird im Lichte der Trederschen Tetradentheorie diskutiert. Die Erscheinungen des Newtonschen Eimerversuchs und Sagnac‐Experiments werden feldtheoretisch untersucht und gezeigt, daß beide Experimente nicht im Widerspruch zur Relativität der Beschleunigung stehen. Das Prinzip der Konstanz der Lichtgeschwindigkeit behält auch im Rahmen der allgemeinen Relativitätstheorie seine Gül

摘要:

AbstractIt is shown for a special bistable reaction‐diffusion model that an external noise shifts deterministic bifurcation maps or generates new bifurcations. Numerical results and an analytical approximation for the bifurcation map of the stationary probability density distribution of the mean concentration in a discrete model are given. The functional Fokker‐Planck equation is solved approximat

摘要:

AbstractA new method for nmr self‐diffusion measurements, the spin‐locking echo technique, is presented. As with the stimulated‐echo technique, its application is recommended for large ratiosT1/T2of the longitudinal and transverse relaxation times. It is shown that the new technique is less sensitive to disturbances due to residual field gradients, thus allowing the determination of smaller self‐diffusion coeff

摘要:

AbstractVarious expressions for nonlocal gauge invariant meson, baryon and gluonium operators are considered which differ from one another not only by the colour representations of the phase factors used but also with respect to the underlying contours. Renormalization and short distance properties of these operators turn out to be unique as long as the contours chosen are smooth ones. Anomalous dimensions of mesons and baryons can be expressed in terms of a gauge independent anomalous dimension of the quark field. Furthermore, composite operators distinguished by the absence of renormalization are discussed.
