研究了一类带强迫项的二阶微分方程,利用Riccati变换和完全平方技术,得到了该方程区间振动性的结果,最后用实例对所得结果进行了说明.
A class of second order differential equations with forced term is investigated. By using Riccati transformation and integrality square technique, interval oscillation criteria of the equation are established. Some examples are discussed to illustrate the theorems.
