In this paper, searching technology of product information based on knowledge was researched. On the aspect of cognition, we researched the relation between user\'s cognition and designer\'s cognition, explored the knowledge flow in the process of product development, set up a matching model between user\'s knowledge and designer\'s knowledge, brought forward a modeling method based on users\' cognition, and set up a measurable model of product feature; coded and decoded product form element, set up a computer aided product form design system and image evaluating system based on the result of measurement. Accordingly, the product style and product image were systematically discussed, the recognition space of product style and image was constructed, the factors that affect product style and image were put forwards and analyzed, and the relation between product image and form elements was tested by experiments. Furthermore, the product automatic recognition technologies were discussed.And then, with the media of concept model and the kernel of parameter technology, a mathematic model that describing product layout design by constraints and rules was presented. Furthermore, a product design integration system based on imagery thinking including product fonii base system based on imagery thinking, product form design system based on imagery thinking and product form intelligent design system based on space layout were set up, which tested the system and provided a new way for product innovative design.

Scientific classification of soils is the basis of utilization and exploitation of soil resources. However, Soil Taxology, characterized by quantification, standardization and internationalization, is not popularized by far. So it is necessary to study its relationship with soil genesic classification and its application for agriculture and environment.
土壤的科学分类是土壤资源开发和利用的基础,土壤的系统分类以定量化、标准化和国际化为特点,但其大众化水平有待进一步提高,尚需加强与土壤发生分类的参比研究,并深化其在农业生产应用、土壤环境评价等方面的实践意义。

Then, according to phase space reconstruct technique from one-dimensional and multi-dimensional time series, the quantitative criterion and rule of system chaos which combine neural network, analyses, computations and sort are conducted on EEG signals of five kinds of human consciousness activities. The author finds that statistic results of the determinism computation in time series indicate that chaos characteristic may lie in human consciousness activities, and central tendency measure is consistent with phase graph, so it may become one division way of attractor; approximate entropy of different subjects exists discrepancy; correlation dimension and Lyapunov exponent of different consciousness activities indicate that attractors of human activities are all fractional; nonlinear quantitative criterion and rule, which unites neural network, can distinguish different styles of consciousness activity in principle, and the result of sortation takes on that consciousness activity type of arithmetic is distinguished more easily than that of abstract.
采用一维与多维时间序列相空间重构技术和系统混沌的定量判据准则,结合神经网络,对五种思维作业方式的脑电信号进行了分析、计算与分类,发现确定性计算的统计结果表明人类的意识活动中可能蕴含混沌特性,中心趋向测量(Central Tendency Measure,CTM)与相图吻合较好,可作为EEG吸引子的区分方法之一;功率谱分析反映出单个受试者的各种意识形态的差异很小,但是不同意识活动谱中的活跃频段还是略有差异的;个体之间的近似熵存在差异,同种状态下近似熵大的人可能具有更好的创新性;关联维数和Lyapunov指数的计算结果表明大脑的运动落在具有分维的奇怪吸引子上;非线性量化方法与神经网络相结合,可对人脑思维活动进行较好的分类,并且从分类结果来看数理计算类思维活动较抽象类思维活动有着更好的区分度。

The traditional algorithms of classification are no longer suitable because of the effect of the concept drift in data streaming. The research on fast and stable data mining systems with high accuracy has become more valuable in both theory and practice. The effect of low frequency concepts on time and space performance is studied and an LFCR algorithm is proposed in this paper, which reduces the low frequency concept with some mechanisms. The extensive experimental study shows that LFCR has improved performance in classification in comparison with RePro.
