The constructional method of problem processing system is gained.

3确定了问题求解系统的构造方法。

The ICM method based on this thesis, the topology optimization problem of continuum structures is solved.

本文主要工作内容是：(1)利用高阶缩并方法对广义几何规划问题求解。

Some researcher give a modified algorithm which generates a convergent sequence if one of the operators is continuous.

虽然已有文献中这个算法得到了改进，但仍要求其子问题求解是精确的。

Good agreements are found while comparing the FE analysisresults with available analytical results. It shows that the FE method of tireanalysis under driving state and the method dealing with large slip frictionalcontact problems are correct and reliable.

基于本文提出的大滑动摩擦接触问题求解方法，通过在胎圈和轮辋接触节点上施加滑移滚动约束，提出了匀速滚动条件下轮胎驱动特性有限元分析方法，并编制了有限元分析模块。

It shows that the FE method of tireanalysis under driving state and the method dealing with large slip frictionalcontact problems are correct and reliable. The properties of tires under steady cornering state are studied with FEmethod and experiment. Based on the presented contact solution algorithm, a FEmethod is carried out to analyze the properties of tire under steady corneringstate via imposing slip-rolling-constraints on tire bead nodes which contact therim, and the modules are programmed. The mechanical properties anddeformation of tire under pure steady cornering state and steadycornering-driving state are analyzed, and the results show good agreement withthe experimental data.

对匀速侧滑条件下轮胎侧偏特性进行了试验研究和有限元分析研究，基于本文提出的大滑动摩擦接触问题求解方法，通过在胎圈和轮辋接触节点上施加侧偏滚动约束，得到了匀速侧滑条件下轮胎侧偏特性有限元分析方法，编制了有限元分析模块；利用本文给出的有限元分析方法，分析了轮胎在匀速纯侧滑和侧滑-纵滑联合工况下受力变形特性，分析了侧偏角和载荷对轮胎侧偏特性的影响。

The problem solver uses the TMS to record the reasons that facts are derivable so that facts need not be rederived during the course of the search.

问题求解器使用TMS记录事实被推出的理由，使得在搜索的过程中这些事实不必重新推导。

Then it is often possible to reduce the dimensionality of the data without losing important information.

这时可以只选择有助于问题求解的变量而不考虑其余的变量，从而减少了数据的维度。

The third is the evolution of knowledge: Because of the limit of human's cognition, knowledge in a person's brain keeps on evoluting. So the knowledge in an intelligent system which simulates cognition should also evolute. The evolution of knowledge in the CM includes the evolution of background knowledge and problem solving knowledge.

最后是系统知识进化的思想：因为人的认识能力的局限性，人的知识一直处于不断的进化过程中；体现知识模拟的知识库系统也应当是进化的；CM方法论中的进化过程包括背景知识进化和面向问题求解知识对象的进化，为此，CM方法论中定义了关于知识对象及其背景知识的一系列操作。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
