The main structure around m = 2.15 GeV first observed by the Argonne group in the spin-dependent total cross section ΔσL is confirmed in the energy range available at SIN. A simultaneous study of the scattered particles at small angles has been carried out with success and gave the spin-correlation parameter A00kk for the pp elastic scattering and for the reaction pp → π+d. The contribution of the 3-body reactions to this spin-dependent total cross section has been deduced and found to be lower than the contribution of the π+d reaction even at 583 MeV. 相似文献

Second-order rate constants for the Diels-Alder reaction of 90 aromatic hydrocarbons with maleic anhydride, measured spectrophotometrically at 91.5° in 1,2,4-trichlorobenzene, are correlated with various reactivity indices, namely Herndon's structure count ratios, second-order perturbation energies, Brown's paralocalization energies, Hess-Schaad resonance energy differences and Polansky indices. Apart from the latter theory, all methods yield satisfactory correlations, with the Hess-Schaad theory being marginally better. An explanation is given why the Hess-Schaad theory is superior to para-localization theory although both are based on Hückel π-electron energies. The observed regioselectivity is correctly accounted for by all except Polansky's theory which yields incorrect results for certain phenes and starphenes. 相似文献

The use of different plasma models for composition calculations of nonideal plasmas can result in very different electron concentrations for the same experimental situation characterized e.g. by the measured temperature and pressure. This gives rise to misunderstandings at comparison of theoretical and experimental results. For extreme conditions i.e. in the region of the supposed plasma phase transition results of solid state physics give us the possibility to rule out some plasma models. 相似文献

Combining biologic pretreatment with storage is an innovative approach for improving feedstock characteristics and cost, but
the magnitude of responses of such systems to upsets is unknown. Unsterile wheat straw stems were upgraded for 12 wk with
Pleurotus ostreatus at constant temperature to estimate the variation in final compositions with variations in initial moisture and inoculum.
Degradation rates and conversions increased with both moisture and inoculum. A regression analysis indicated that system performance
was quite stable with respect to inoculum and moisture content after 6 wk of treatment. Scale-up by 150× indicated that system
stability and final straw composition are sensitive to inoculum source, history, and inoculation method. Comparative testing
of straw-thermoplastic composites produced from upgraded stems is under way. 相似文献

Let p be a prime number and a natural number. If E is a r-connected finite CW-complex of dimension at most pr, then E is an example of a
p
-Anick space. For p > 2 we construct a commutative cochain algebra over that is an -model of the free loop space on a p-Anick space, i.e., its cohomology algebra is isomorphic to the mod p cohomology of the free loop space. For p-Anick spaces that are p-formal, such as spheres and projective spaces, we define an even simpler commutative free loop space model that applies for
all primes p. We then use the simplified model to compute the cohomology algebras of a number of free loop spaces explicitly.
