Experimentally determined volumetric properties of the liquid binary mixture of {water (1) + glycerol (2)} were processed to calculate the changes of the following thermodynamic parameters with pressure: excess molar Gibbs free energy, ΔPoPGmE, excess molar entropy, ΔPoPSmE, excess molar enthalpy, ΔPoPHmE, as well as the enthalpy of mixing of water and glycerol, HmE, at 100 MPa. The mixing enthalpies of water and glycerol, HmE, became more exothermic with pressure increasing at all temperatures studied.  相似文献

The Au Lβ2 visible satellites, Lβ2 and Lβ2 were measured around the L1 absorption edge using a high-resolution Johann-type spectrometer at BL15XU, SPring-8. The relative intensities of the Lβ2 and Lβ2 satellites to that of the Lβ2 line exhibit an abrupt jump at the L1 threshold. The results suggest that the origin of the Lβ2 satellites is mainly the L1L3M4,5 Coster–Kronig transitions.  相似文献

Very extensive multiconfiguration Dirac–Fock calculations with the inclusion of the transverse (Breit) interaction and QED corrections have been carried out on thorium to elucidate the structure of various satellite (additional vacancies in N and/or O shells) and hypersatellite (additional vacancies in M or M and N shells) Mα1,2 (M5N6,7) and Mβ1 (M4N6) lines in its X-ray spectra. For each type of lines two theoretical spectra have been synthesized: one being a sum of the Lorentzian natural line shapes and the other one being a convolution of the sum of the Lorentzian natural line shapes with the Gaussian instrumental response. The obtained theoretical results will be very helpful in reliable and quantitative interpretation of various experimental M-X-ray spectra of thorium target bombarded by different light and heavy projectiles (such as O and Ne ions).  相似文献
