查询词典 implicit difference scheme

To establish the constitutive equation of material, the metric tensor for stress , strain and their transformation equations between different configurations are derived, and basic theory of finite deformation as well as elasto-plastic deformation criterion are studied. By analyzing the applicability of different element models, four-node quadrilateral degenerated Mindlin isoparametric element is adopted because of its good versatility, and the element stiffness matrix is derived. The static implicit elasto-plastic finite element equation for complex skin stretch-forming is put forward based on Updated Langrange formulation.

本文首先系统地阐述了有限变形的相关基本理论，针对板料成形建立了应力应变度量张量及其相应的转换关系；介绍了材料的屈服准则、塑性变形强化规律、塑性流动规律以及加、卸载准则，并在此基础上建立了有限变形各向异性弹塑性本构方程；对板料成形的单元模型进行了分析，针对飞机蒙皮零件特点，采用通用性强的四节点四边形退化Mindlin等参壳单元进行成形模拟，并导出其单元刚度矩阵的具体形式；基于以上研究，以逐级更新Langrange描述的持续虚功率原理为基础，建立了率形式的复杂蒙皮拉形过程静态隐式弹塑性有限元方程。

To take the "nothing but" condition to be an implicit claim of microphysics would be to build the thesis of physicalism into microphysics, which philosophers such as Jackson and Chalmers, who reject physicalism, should be reluctant to do.

要把"只有"条件作为微观物理的蕴涵，需要把物理主义主张建设到微观物理学上，而这诸如Jackson 和 Chalmers这些拒绝物理主义的哲学家，会难以做到这个。

Engineering design problems have two characteristics: the design variables are often monotonic in the objective function and constraints. Moreover, the objective function and constraints are often implicit functions which cannot be expressed explicitly in terms of design variables.

工程最佳化设计问题通常有两个特性：设计变数在目标函数与限制条件常具有单调性，且其目标函数与限制条件常为内隐式函数，也就是不能以设计变数来表示其外显形式。

In this paper, a new montage mesh fusion method based on variational interpolating implicit surfaces is proposed.

提出一种基于变分隐式曲面的网格融合新方法。

A "generation balance" drawn up by Bernd Raffelhüschen and Stefan Moog for the Market Economy Foundation in Berlin weighs the cost of today's spending commitments for tomorrow's taxpayers. The debt of the public sector was 65% of GDP in 2007; adding in unfunded future costs of pensions, health care and other schemes, the state's implicit debt jumps to 250% of GDP.

柏林市场经济基金会的Bernd Raffelhüschen和Stefan Moog所制定的"代代平衡"计划评估了目前政府为未来纳税人支出的成本。2007年公共事业的赤字达GDP的65%；本来就没有资金来源的养老金，医保和其他项目的成本负担更加沉重，国家背后的债务已悄然跃至GDP的250%。

I also love "Yamagiwa see to smoke, Takenaka glimpse of the sunset," an implicit Mi;"edge of the village green trees together, Castle Peak Guo oblique" harmony;"moonset Wu Ti frost sky, Jiangfeng fishing boat on the unhappy sleep" warm .

我还爱"山际见来烟，竹中窥落日"的隐谧；"绿树村边合，青山郭外斜"的和谐；"月落乌啼霜满天，江枫渔火对愁眠"的温馨。

But since it is required of any theoretical treatment that it not leave its basis implicit, but declare it openly, so that it may be clear with what its argument is concerned, I say, hastening to deal with the question, that I call 'vernacular language' that which infants acquire from those around them when they first begin to distinguish sounds; or, to put it more succinctly, I declare that vernacular language is that which we learn without any formal instruction, by imitating our nurses.

任何理论思考都要求其基础明确公开，因此应该弄清楚讨论的问题是什么，我们要考虑的是我称之为"俗语"的东西，是婴儿开始分辨声音时从他周围的人那里学来的，或更简练地说，即我称之为俗语的是我们没有通过正规指导，而是通过模仿保姆而学会的语言。

A new nonlinear multistep method is constructed based on the implicit Euler method in this chapter, named Schur product multistep method.
