The result of simulation shows that these three kinds of method have much more quick constringency ratio and high precision than traditional method, which provides the important theory to real-time realization of neural network for nonuniformity correction.

仿真实验表明这三种方法较传统的随机给定法训练收敛速度快、精度高，为神经网络非均匀性校正法走向实时实现提供了重要的理论参考。

There are simple rules and quick convergence speed for SDPS.

该方法给出的适配粒子群算法规则简单、收敛速度快，得到的解集有较好的分散性和均匀性。

The aseismic control for pile-foundation bridges considering soil-structure-interaction was studied. There are two problems were solved:(1) The coefficient matrix is singularity because the elements of rotational degree in mass matrix equal to zero due to the flexiblity of the pier.(2) The iteration of control gain was not convergent because the dumped mass of the beam is very large comparing with that of the pier.

为将Smith[162]方法用于桥梁结构，本文解决了如下两个问题：(1)以弯曲变形为主的桥梁结构，其质量矩阵中相应于转动自由度的元素数值为零，由此导致等效固基模型中的系数矩阵奇异；(2)桥梁结构堆聚到顶部节点的梁体质量很大，由于质量分布不均匀导致控制增益的迭代计算不收敛。

A non-uniformly windowed pyramidical architecture is proposed, the normalizations of the feature vectors of two extraction algorithms are investgated and the Polak-Ribiere learning algorithm is modified to guarantee the weight vector not to converge to non-stable local minima.

文中提出了一种带非均匀窗形式的金字塔状多层神经网络模型I研究了两种特征提取方法的向量规整问题，改进了Polak—Rjbiere学习算法并证明它能够保证连结权向量不收敛到非稳定局部极小点。

Some techniques, such as niching technology based on sharing scheme, tournament selection with elitism, and uniform crossover, are used to improve the performance of GA and MGA.

采用均匀交叉算子、复制与联赛相结合的选择算子，以及基于共享机制的小生境技术可以大大提高遗传算法的性能，加快算法向最优结果的收敛。

In the optimization iteration, the levelset function values of nodes are considered as design variables. To computedifferences normally, the Heaviside function is handled for smoothing, theregularized Heaviside function is selected to avoid the oscillation inhomogenizations method, and the results can converge smoothly.

在优化迭代过程中，节点上的Level Set函数值被看作是设计变量，并且为了便于微分计算能够正常进行，对Heaviside函数及其导函数做了光滑化处理，选取了一种正则化的Heaviside函数，避免了均匀化方法中出现的振荡现象，可以平稳地收敛到最终结果。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
