In order to investigate the one-dimensional beam ordering in HIRFL-CSR, the ion beam of 58Ni19+ with the energy of 6.39 MeV/u was accumulated in the main ring of HIRFL-CSR with the help of electron cooling. The maximum accumulated ion beam intensity in the 10 seconds was measured, and the lifetime of ion beams was measured. The momentum spread of the ion beam varying with the particle number was measured during the ion beam decay, the power exponent was derived from these data, in additional, the momentum spread in the case of a constant particle number was plotted with the angle between ion and electron beams and electron beam profile. The oscillation and shift of the central frequency of the ion beam were observed during the experiments when the angle was large.
