摘要：

Consider an inhomogeneous contact process on Z(1) in which the recovery rates delta(x) at site I: are i.i.d. random variables (bounded above) while the infection rate is a constant epsilon. The condition uP(-log delta(x) > u) --> + infinity as u --> + infinity. implies the survival of the process for every epsilon > 0.
