查询词典 variational

When production costs fluctuate and yet,at the same time,selling price can not be adjusted because it is determined by the equilibrium of the entire market,at the aggregate level,where different players have different cost advantages in different products and processes. We show that the variational inequality approach is suitable for dealing with this differential game.

当产品生产成本大幅波动时，产品的销售价格并不能完全的由单独的生产商随意根据自身成本变动调整，因为在寡头垄断市场中，产品的最终售价须由市场的所有参与者共同确定，而不同的厂商在不同的产品与工艺流程中有不同的竞争成本优势。

Lions and some other variational methods, we prove the existence of nontrivial solutions of the equations under the Dirichlet boundary condition.

在Hg~(2 )处理的96h内，细叶蜈蚣草SOD和CAT活性变化规律基本是一致的，只是酶活性的相对大小有所变化，即细叶蜈蚣草SOD和CAT活性随Hg~(2 )增加先上升后下降。

The dissertation presents a mathematical modeling approach for the high-speed flexible linkage mechanisms equipped with bonded piezoelectric sensing/actuating elements employing a mixed variational approach with Hamilton's principle in conjunction with the finite element formulation. This model includes both the terms coupling the elastic and rigid-body motions of linkage mechanisms and the terms coupling the elastodynamics and piezoelectricity of the elements, incorporating their effects upon the mass and stiffness matrices which are in general non-symmetric.
