摘要：

In this paper, we consider a thin-film equation with nonlocal source, which was studied by Qu and Zhou (2016) [11], where the authors derived the conditions for global existence, blow-up and extinction. We consider the case that the initial energy is positive and establish a blow-up result for this case. Furthermore, the upper bound of the blow-up time is derived. (C) 2016 Elsevier Inc.
