The first quasi-static stretch of the two limiting systems of filler loaded rubber have been investigated. One of them is found by filler to matrix contacts only, the other by crosslinking permanently the matrix. In this case filler-matrix contacts are made by adhesion. The experimental results were described in terms of an extended van der Waals approach. It is illuminated that different filler to matrix contact (permanent bonds or adhesion) lead to different deformation mechanism, substantially affecting the reinforcement. Moreover, filler induced local field-modifications due to the boundary value problem can be understood with the Einstein-Smallwood approach independent of the kind of the filler to matrix contacts. 相似文献

The observation of an enhancement in the production of low energy pions in the Cu(p, +)X reaction is confirmed. The width of the bump is about 5 MeV around 350 MeV. A similar enhancement appears at 330 MeV for C(p, +)X but the width has not been measured. An attempt to observe this behaviour in Cu(p, )X is described. From the data one cannot conclude about the existence of a structure around 350 MeV proton energy. The lack of resolution in the spectrometer may have washed out the small effect expected from
+ measurements. 相似文献

We studyT-odd triple momentum correlations in exclusive semileptonic -decays into three pseudoscalar mesons. We define asymmetry ratios that measure theseT-odd correlations and show how to separate the unitarity contribution from the trueCP-violating contributions. TheCP-violating contributions to the asymmetry ratios would have to come from new non-Standard Model sources as theCP-violating Standard Model contributions to the asymmetry ratios are zero. We discuss two extensions of the Standard Model that give rise to nonvanishingCP-violating triple momentum correlations, namely a left-right symmetric model and a multi Higgs boson model. Numerical results on triple momentum correlations are given for the three-pseudoscalar meson final statesK

We report on the first exclusive measurement of the 2π production in NN collisions atT p=750 MeV using a H2 cluster jet target and the WASA/PROMICE detector at CELSIUS. In the invariant-mass spectrum $M_{pp\pi ^ - } $ we observe a narrow peak at 2.063(2) GeV with a 4σ deviation relative to the MC simulations for the conventional nonresonant 2π production process. The finding is in agreement with the hypothesis of a narrowπNN resonance withI(JP)=even (0?), calledd′, postulated recently to describe the peculiar resonance-like behavior of the pionic double charge exchange on nuclei. 相似文献

Data accumulated recently for the exclusive measurement of the pp $ \rightarrow$ pp $ \pi^{+}_{}$ $ \pi^{-}_{}$ reaction at a beam energy of 0.793GeV using the COSY-TOF spectrometer have been analyzed with respect to possible events from the pp $ \rightarrow$ nn $ \pi^{+}_{}$ $ \pi^{+}_{}$ reaction channel. The latter is expected to be the only $ \pi$ $ \pi$ production channel, which contains no major contributions from resonance excitation close to threshold and hence should be a good testing ground for chiral dynamics in the $ \pi$ $ \pi$ production process. No single event has been found, which meets all conditions for being a candidate for the pp $ \rightarrow$ nn $ \pi^{+}_{}$ $ \pi^{+}_{}$ reaction. This gives an upper limit for the cross-section of 0.16μb (90% C.L.), which is more than an order of magnitude smaller than the cross-sections of the other two-pion production channels at the same incident energy. 相似文献

The evolution of the distribution of nanodefects formed on the surface of polished copper foils under tensile stresses is investigated. It is found that nanodefects form four ensembles. The energies of formation and the mean sizes of nanodefects in two consecutive ensembles differ, respectively, by a factor of three. When the concentration of nanodefects in a particular ensemble reaches a thermodynamically optimum value (≈5%), some of these nanodefects annihilate and the other nanodefects transform to nanodefects of the following ensemble. The load applied to the sample continuously generates nanodefects comprising the first ensemble, which leads to periodic oscillations of the nanodefect concentration in all four ensembles. 相似文献

Die Verstromung von Abwärme ist ein vielversprechender Ansatz zur Steigerung der Energieeffizienz vieler Prozesse. Hierfür bietet die Thermoelektrik große Vorteile in Bezug auf Systemkomplexität, Wartungsfreiheit und Langzeitstabilität. In den letzten Jahren wurden neue, effizientere thermoelektrische Materialien entwickelt. Auch die Aufbautechnik wurde verbessert. Auf dieser Basis werden nun thermoelektrische Module in Systemen verschiedener Anwendungen erprobt. Dazu zählen Fahrzeuge, Blockheizkraftwerke und die industrielle Abwärmenutzung zum Beispiel in Stahlwerken. Durch Produktion im industriellen Maßstab kann die Thermoelektrik zukünftig so wirtschaftlich werden, dass sie auf vielen Anwendungsgebieten einen spürbaren Beitrag zur Senkung der CO2‐Emissionen leistet. 相似文献
