摘要: The measurement of the exclusive light hadron decays of the ψ" in e+e- experiments with significant interference between the ψ" and continuum amplitudes is discussed. The radiative correction and the Monte Carlo simulation are studied. A possible to verify the destructive interference is proposed for the detectors with energy-momentum resolution of (1~2)%.

摘要: This paper describes the numerical study on film cooling effectiveness and aerodynamic loss due to coolant and main stream mixing for a turbine guide vane. The effects of blowing ratio, mainstream Mach number, surface curvature on the cooling effectiveness and mixing loss were studied and discussed. The numerical results show that the distributions of film cooling effectiveness on the suction surface and pressure surface at the same blowing ratio (BR) are different due to local surface curvature and pressure gradient. The aerodynamic loss features for film holes on the pressure surface are also different from film holes on the suction surface.
