This paper introduces the concept of automated intelligent tire design as basis, and then systemically presents the general framework of CAD 3-D digital tire model design platform. Its modules include the demand representation, demand preanalysis, product list generation, product list modeling, testing, tires knowledge-base and tire parts-base. The realizing process and key techniques of the product list modeling module are described, including calculation principle of groove section and groove modeling scheme ,and so on. This paper also introduces an improved algorithm of calculating groove centerline. Finally CATIA platform and VBA toolkit-based tire design system is established under detailed demand representation type.

作者提出了相应的理论解释，并从析出相控制的角度提出了对大生产的建议。

With the limitation of the line detection based on traditional Hough transform that the information of the length and the end points of the line is unavailable, a new algorithm which makes use of the accessional strategy based on precognition information is put forward to meet the demand for more information of the line, simulation results show this method is effective. Finally, the whole process of airport target recognition is presented and the result images are also given.

使用分形方法提取目标的特征，在知识指导下，提出了一种基于目标特征模型的降维的形态学分形维数计算方法，对传统分形方法进行了改进，从理论上推证了算法的合理性，并对算法进行了仿真分析；针对传统Hough变换无法获得线段端点和长度信息的局限性，提出了一种基于目标特征先验知识的Hough变换融合策略，通过引入目标先验知识，可以有效地获得直线信息；对信息多而复杂的机场目标采用基于知识的目标识别方法，使用置信度模摘要型实现不确定推理，对目标进行识别判断，将知识贯穿于整个识别过程中，对目标进行了有效地识别。

In the last chapter the author suggests that existing Chinese legislation shall endorse the validities of the precontract.It will enrich the connotation of contract and improve the system of contract law in China.At last,the author proposes to develop the regulation over precontract in the framework of contract law in China.

在本文的最后一章中作者提出了在立法上明确承认预约合同效力等解决商品房认购书纠纷的建议，以期能丰富契约概念的内涵，完善契约立法体系内部的结构，并提出在我国合同法框架内设立预约制度的构想。

This thesis also points out that not only the form but meaning should be taken into account and that the predicator in a sentence the verb or adjective as Predicate should be considered as a basis . In the light of theses points , the thesis proposes an optional sequence of semantic roles to determine the Subject in a mutiple NPs sentence whereby every mutiple NPs sentence may be analysed as having only one Subject .

本文还提出确定汉语主语不仅应考虑形式因素，而且也应考虑意义因素，确定主语应以句中谓词为基点，并据此提出了一条确定汉语多项NP句主语的语义角色优先序列，从而将多项NP句全部分析为只有一个主语的形式。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
