    "abstract": "The space and time evolution of initial parton production in\nultrarelativistic heavy ion collisions is investigated within the framework of\nperturbative QCD which includes both initial and final state radiations.\nUncertainty principle is used to relate the life time of a radiating parton to\nits virtuality and momentum. The interaction time of each hard or semihard\nparton scattering is also taken into account. For central $Au+Au$ collisions at\n$\\sqrt{s}=200$ GeV, most of the partons are found to be produced within 0.5\nfm/c after the total overlap of the two colliding nuclei. The local momentum\ndistribution is approximately isotropical at that time. The implication on how\nto treat correctly the the secondary scattering in an ultimate parton cascading\nmodel is also discussed.",
