In this work a hydrodynamical model is presented in order to explain physical phenomena appearing in nucleus-nucleus collisions. The model is based on a shock wave propagation in the fluid nuclear matter. The Burger- de Vries equation of shock waves is treated in the framework of mathematical topology. Experimental data for five pairs of nuclei is used in order to demonstrate the viability of the model. 相似文献

The aim of this paper is to study the asymptotic behavior of one- dimensional modified Stockwell transform of a tempered distribution signal through the quasiasymptotic behavior at origin or infinity of the signal itself. More precisely, we give some Abelian results which mean that we derive the asymptotic properties of the S-transform of a tempered signal from the quasiasymptotic properties of the signal itself and we do also the opposite. So, we also give some Tauberian results which describe some quasiasymptotic properties of the tempered signal by means of the asymptotic properties of its Stockwell transform. 相似文献

This work is concerned with an optimal control approach to stochastic nonlinear parabolic diffusion equations with monotonically increasing nonlinearity. This approach leads to sharper existence and uniqueness results under minimal growth conditions on nonlinear diffusion coefficients. 相似文献

We give examples of Stein domains D in C 2 such that C 2 ? D is either completely pluripolar or union of germs of (principal) hypersurfaces not intersecting D such that D fails to be meromorphically convex in C 2. © 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim 相似文献

A diode laser spectrometer was used in the laboratory to study 13CO2 and 18O12C16O line intensities and self-broadening coefficients near 2.04 μm. The spectral region ranging from 4896 to 4903 cm−1, which is suitable for in situ laser sensing of both isotopologues in the lower Martian atmosphere, was investigated using a distributed feedback GaInSb diode laser. Five lines of the (2 00 1)II←(0 0 0) band of 13CO2 and seven lines of the (2 00 1)II←(0 0 0) band of 18O12C16O were carefully revisited. The measured intensities and self-broadening coefficients were thoroughly compared with relevant molecular databases. 相似文献
