摘要：

We investigate the evolution of matter density perturbations in a universe with a cosmological term that decreases with time as Lambda alpha a(-m). For fixed values of Omega(m0) the power spectrum is constructed and we show that it is only slightly modified when the parameter m is changed from m = 0 to m = 2. Some properties concerning the peculiar velocity held are also discussed.
