Abstract：
In this paper, a non-steady state solution for the propagation equation is obtained by means of the Green function. We consider several models of the source function in the calculation. The electron spectrum derived from these kinds of source function shows very different properties. Our calculations suggest that the cosmic ray is not in an equilibrium state. It is also pointed out that the cosmic ray can not be considered as the remnants origining from a dramatic astrophysical process in primordial period when our Galaxy began to form. Both the results given by the continuous ejection model and the piont-source model with impulsive ejection can be used to account for the constant slope of the electron spectrum. Perhapes the Pulsar, or rotating neutron star, and the Supernowt may be served as the most likly considerates for the sosmic ray source.
