摘要：
In this paper, for a second order differential equation with a middle term, we will establish some new criteria for disconjuagcy on an interval I, i.e., any nontrivial solution of the equation has at most one zero on this interval. We, also establish some sufficient conditions for disfocality and obtain a lower bound for an eigenvalue of a boundary value problem. Some examples are considered to illustrate the main results.
