| 英文摘要 | 3-D Monte Carlo simulations of 4 x 105 pulsars based on the undisturbed finitely thick disk gravitational potential derived by Peng et al. (1978) are made in this paper under four combinations of the two gravitational potential parameters (hz\ = 0.001 kpc, hz2 = 0.325 kpc) and two initial velocity distribution parameters (av\ = 115km/s, crv 108yr); but in relatively short time < 2 x 107yr, the effect is very small, moreover, the time dependence of the cumulative scale height is linear. In long period the initial distribution of velocity also has obvious influence on the cumulative scale heights. In the situation of hZ2 = 0.325 kpc and crv2 - 200km/s the cumulative scale height is 0.5960.005kpc in the range 5 < r < 11 kpc at time t = 9.22 x 106 yr. |
