英文摘要	We restudy the Lee-Weinberg time-evolution equation including the R-parity violation. We carefully analyze the influence of the boundary conditions, equation of state, SUSY parameters, especially the R-parity violation, and other factors on the time-evolution of the SUSY cold dark matter. Our numerical results show that without R-parity violation, only two ranges 20 < m(χ10) < 30 GeV and 75 < m(χ10) < 110 GeV can be consistent with data, if 30 < m(χ10) < 75 GeV, there must be at least two kinds of heavy particles contributing to the cold dark matter. However, with the R-parity violation, the heavy neutralino can be dark matter constituent, but it must decay and the R-parity violation parameter is constrained by the present data.
