So in this paper, combined the CT method and the AntNet routing algorithm, using the multi-agents technique, the artificial cognitive model--BP-CT ant routing algorithm is constructed. In this algorithm the agents have the simple artificial cognition and can interact with other agents and environment. We simulate this algorithm on OMNeT++ software platform and contrast with AntNet routing algorithm, and analyze the result of simulation.

本文将经济系统中较好体现人工认知特征的CT 交叉目标算法与蚂蚁网络路由算法相结合，使用多智能体技术，使智能体具有了简单的人工认知，通过与其他智能体和环境进行交互，构造了以计算智能为智能体核心的人工认知模型BP-CT 蚂蚁网络路由算法，并在OMNeT++网络仿真平台上加以实现，并与蚂蚁网络路由算法进行了对比，并对仿真结果进行了比较和分析。

A new particle swarm optimization, PSO with bounded mutation operator, was developed. In contrast to the original PSO, in this algorithm, PSO with bounded mutation operator would make the particles redistributed cquably close to boundary when place of particle exceeds feasible region during iteration.

提出了一种新的粒子群优化算法——带边界变异的PSO，其原理是：在迭代的过程中，当粒子的位置超出可行域时，带边界变异的PSO让粒子的位置重新均匀分布在边界附近；当粒子的速度超出可行域时，则使其均匀分布到整个可行区间，而不是像原始PS0那样在这2种情况下都只是简单地取边界值。

In contrast, 8 of 10 (80%) of symptomatic patients with features of chronicity in ileal biopsies progressed to a diagnosis of CD, as did 2 of 5 (40%) symptomatic patients with focal active ileitis.

相反，10例有症状且显示慢性回肠炎特征的患者中有8例（80%）进展成CD，另外5例有症状且显示局灶活动性回肠炎的患者中的2例（40%）亦是如此。

After traversing a hundred paces, skirting a wall of the fifteenth century, surmounted by a pointed gable, with bricks set in contrast, he found himself before a large door of arched stone, with a rectilinear impost, in the sombre style of Louis XIV., flanked by two flat medallions.

他走上百来步，到了一道十五世纪的墙脚边，墙上有用花砖砌的山字形尖顶，沿墙过去，便看见一扇拱形石库大门，一字门楣，配上两个圆形浮雕，具有路易十四时代的浑厚风格。

By the end of 2008, China's civil motor vehicle holdings reached 64.67 million units, but the ratio of vehicles installed with GPS was very low to merely 2% of the total, in sharp contrast with the 59% in Japan.

截至2008年底，中国民用汽车保有量达6，467万辆，但车载导航加载率非常低，仅为 2%，而日本的汽车车载导航系统安装率高达59%。

At least one suborder of trilobites, the Agnostina , are thought to be primarily eyeless . None have ever been found with eyes. In contrast, a few secondarily eyeless species (in which a clear evolutionary trend toward reduced eye size with eventual disappearence of eyes altogether) have developed within several groups, even those known for large, well-developed eyes ( e.g., Phacopina).

在最少一个亚目的三叶虫 Agnostina 中，通常是盲目的，这类三叶虫从来没有发现过眼睛的构造，以此相对的，一些很少的其他亚盲目的种（一些进化了简单的眼睛的物种）是比较进化的，甚至是一些大个体的，有很好的眼睛发育的种，如 Phacopina。

In contrast, atrophy in temporal cortices correlates with stage suggesting damage to this area progresses with disease duration.

而颞叶皮层萎缩的进展情况与痴呆所处阶段有关，这表明，随病程延长，颞叶受损加重。

The lungs of CDH fetuses were hypoplastic compared with normal controls and had thick walled septa with poorly developed saccules. In contrast, Dex and EGF fetuses showed improved mesenchymal differentiation with well-developed saccules and thin-walled septae, manifested by radial alveolar counts , mean terminal bronchiole density , ratio of pulmonary mesenchyma and that of pulmonary acinuses.

EGF组肺组织形态明显改善，表现在肺泡间隔变薄，肺泡面积所占比例明显增大，轴向腺泡计数较CDH组及Dex组均有明显增加，其平均终末支气管密度较CDH组改善明显，但仍少于正常对照组。

Results showed that the activity of soil poly-phenol oxidases and acid phosphatase, and soil respiration were suppressed by Starane at 0.5 and 5 mgkg^(-1) dry soil, respectively, during the first several days of experiment, but were slight promoted thereafter. In contrast, treatment with Starane at 50 mgkg^(-1) stimulated at the beginning of experiment but inhibited following that time the activity of soil poly-phenol oxidases and acid phosphatase and soil respiration. Activity of urease was stimulated at the beginning but inhibited in the following days by Starane at 0.5 and 50 mgkg^(-1) dry soil, respectively. However, the pattern of stimulation of urease activity at first several days of experiment followed by reduction to the basil level was observed. With respect to invertase, its activity was constantly depressed in the presence of Starane.

结果表明使它隆在0.5mgkg^(-1)和5mgkg^(-1)质量分数时对土壤多酚氧化酶、酸性磷酸酶和呼吸强度的影响为轻微抑制－激活－恢复稳定的趋势，50mgkg^(-1)质量分数时为轻微激活－抑制－恢复稳定的趋势；使它隆在0.5mgkg^(-1)和50mgkg^(-1)质量分数时对土壤脲酶活性的影响为激活-恢复稳定的趋势，5mgkg^(-1)时则处于抑制－激活的趋势；各质量分数的使它隆浓度对土壤蔗糖酶和土壤全酚均为抑制作用，且质量分数越大抑制越强烈。

This study shows that SHF provides an effective method to make premium products with complicated shapes or depth. In contrast to conventional methods such as stamping or drawing, SHF could make products with more complicated shapes through on stage forming, and the products also possess high surface quality. This experiment also shows that material selection and local corner radius design are very important, with proper design we could accordingly complete the forming through on stage.

本研究经由实验验证了板材液压成形技术提供了一项有效的方法来高制造具复杂度或具深度之高品质零件，相对於传统冲压或引伸方式，能够一次成形至更复杂造型成品，且制品具有高表面品质，但材料的选择与局部特徵R角设计仍扮演重要关键角色，需搭配设计适当之特徵R角，如此则能够以最具经济与效益的方式一次成形至所需成品。
