We prove results for the interlacing of zeros of Jacobi polynomials of the same or adjacent degree as one or both of the parameters are shifted continuously within a certain range. Numerical examples are given to illustrate situations where interlacing fails to occur. 相似文献

The reaction Cu2+ + Cl? ? Cu+ + Cl2 has been studied in three different solvents—LiCl—KCl (70–30 % mol), eutectic LiCl–KCl (58–42 % mol) and LiCl–CsCl (55–45 % mol) at different temperatures by visible and near i.r. spectrophotometry. Equilibrium constants are calculated. The standard potential of the couple Cu2+/Cu+ with reference to the standard potential of Cl2/2Cl?, as well as the thermodynamic quantities and in the range 400–600 °C, have been deduced. 相似文献
