摘　　要：本文建立了问题（１．２）的用第一特征值来估计第二特征值的不等式，其估计系数与区间的几何度量无关，其结果在物理和力学中有着广泛的应用．This paper considers the upper bound of second eigenvalue of a lass of differential equation with six orders. The upper bound of is independent of the measure of the domain in which the problem is concerned. This kind of problem is significant in potential application to mechanics and physics.
