By defining a new terminology scatter degree as the supremum of graininess functional value this paper studies the existence of solutions for a nonlinear two-point dynamic boundary value problem on time scales. We do not need any growth restrictions on nonlinear term of dynamic equation besides a barrier strips condition. The main tool in this paper is the induction principle on time scales. 1. Introduction Calculus on time scales which unify continuous and discrete analysis is now still an active area of research. We refer the reader to 1-5 and the references therein for introduction on this theory. In recent years there has been much attention focused on the existence and multiplicity of solutions or positive solutions for dynamic boundary value problems on time scales. See 6-17 for some of them. Under various growth restrictions on nonlinear term of dynamic equation many authors have obtained many excellent results for the above problem by using Topological degree theory fixed-point theorems on cone bifurcation theory and so on. In 2004 Ma and Luo 18 firstly obtained the existence of solutions for the dynamic boundary value .
