According to the engineering practices, the general formula of the horizontal arc beam under differeat loads which consist of distributed loads, couple loads and so on is presented by applying the minimum power theory.
通过工程实践,应用最小功原理,总结出水平圆弧梁在多种荷载作用下的通用计算式,包括不同的均布荷载和力偶等荷载。
In this thesis, we study three problems: Ekeland’s variational principle for set-valued mappings, an equivalent result between a variant of Ekeland’s variational principles and a minimization theorem for set-valued mappings, and the existence results for the solutions of a generalized symmetric vector quasi-equilibrium problem.
Ha [20]得出的Ekeland变分原理,本文得出了关于集值映射的最小化定理。
The implications of the Minimax theorem are tested using field data.
本文利用田野数据对最小最大定理进行验证。
