We study ultrasmall Josephson junctions using the coherent picture to describe the pair dynamics and the semiclassical approach for the quasiparticles. We find that the dynamics depends crucially on the ratio of the superconducting gap energy ..delta..(T) to the charging energy e/sup 2/2C. The pair ''Bloch oscillations'' can be practically observed when 2..delta..(T)>e/sup 2/2C;for 2..delta..(T)
