查询词典 constraint

Based on the ICMmethod,the discrete topological optimization problem about spot-weld's existence or not is transformed into the continuous optimization problem on[0,1].The optimization model is founded with maximizing the structural stiffness as objective and structural strength as constraints.The problem of multi-objectives and multi-constraints is transformed into the problem of single-objective and single-constraint with the K-S function.The displacement and stress are transformed into the explicit function of design variables with the Response Surface Methodology.The optimization model is solved with Sequential Quadratic Program.

The chapter also portions Andre Lefvere\'s concept of poetics into social poetics and personal poetics, in which although the latter is constrained by the former, yet the constraint is relative and they are sometimes identical while sometimes they are not, especially at the specified period of Chinese socio-cultural and historical transformation. The division of the poetical concept does help explain why there exist two kinds of translation strategies in China around the May 4* Movement, and fulfills the translation theory of Polysystem.

我们把勒弗维尔的诗学概念分为翻译的社会诗学和个人诗学，指出虽然个人诗学受社会诗学的影响和制约，但是这种影响和制约也是相对而非绝对的，它们有一致也有不一致的时候，这在五四前后中国特定的社会历史文化转型时期更是如此，从而有效地解释了五四前后中国译坛上两种翻译策略并存的独特现象，提高了多元系统的普适性，丰富和发展了文化翻译学理论。

W anka studied two kinds of dualproblem in finite dimensional space,namely,an extended Fenchel type and FenchelˉLagrange dual based on the conjugate theorem in convex optimization problem.The latter is a"combination"of the classical Fenchel dual and Lagrange dual,which are based on perturbation theory.Then they introduced a constraint qualification whose fulfillment is sufficient in order to guarantee strong duality.

W anka利用有限维空间中凸优化问题的共轭理论，研究了两类对偶问题，即广义Fenchel对偶问题和FenchelˉLagrange对偶问题，后者是经典Fenchel和Lagrange对偶问题的组合，二者都是在扰动理论基础上产生的，还提出了一个约束条件保证其凸优化问题中强对偶成立。
