容器中理想液体小振动的频率ω的计算导致了一个Steckloff本征值问题。提出了一种计算最小特征值的上下界的方法。对于下界计算,应用了Goerisch对Lehmann方法的推广,用有限元构造试函数。舍入误差采用区间算法进行控制。
The calculation of the frequencies ω for small oscillations of an ideal liquid in a container results in a Steckloff eigenvalue problem. A procedure for calculating lower and upper bounds to the smallest eigenvalues is proposed. For the lower bound computation Goerisch’s generalization of Lehmann’s method is applied, trial functions are constructed with finite elements. Rounding errors are controlled with interval arithmetic.
