To this end we shall first consider the following eigenvalue problem. 为此目的,我们将首先考虑下列的本征值问题。
In the end, this paper introduces the theoretical basis of similarity engineering. Using the methods of similarity analysis and similarity measure to calculate the similarity of all of system structure models of chassis, improves the similarity through changing the similarity eigenvalue. 文章最后介绍了相似工程学的理论基础,应用系统相似分析与度量的方法对汽车底盘各系统结构模型进行了相似度的计算,通过改变系统相似特征值提高系统相似度。
It's very difficult to solve the oscillation problem of elastic rod with concentrated mass on the end because the boundary condition in this case is not the one required by Sturm Liouville eigenvalue problem and the functions { X n ( x)} are not orthogonal ones. 由于端点系有集中质量的弹性杆的振动问题的边界条件不是斯特姆-刘维本征值问题所要求的边界条件,分离变数所得到的函数系{Xn(x)}不是正交函数系,故求解十分困难。
