摘要
考虑梁横向振动方程的离散谱估计 ,获得了用前n个离散谱来估计第n + 1个离散谱的上界的不等式的结果 ,估计系数与区间的几何度量无关 。
This paper considers the estimates of discrete spectrum of the horizontal vibration equation of beam. The inequality of the upper bound of the (n+1)th eigenvalue is estimated from the first n eigenvalues by using integral, Rayleigh theorem and inequality estimation .The estimation coefficients do not depend on the measure of the domain in which the problem is concerned. The result is widely used in physics and mechanics.
