In order to find out the biomechanics feature of three joints muscles o f lower limbs by using new skates in push-off phase of speed skating, this article combines the kinetic data obtained by Cybex-Norm and kinematic data obtained by tridimensional analytics by employing the Newton interpolation polynomial f or the first time, draws the curve of muscles moment of two elite female speed- skaters in push-off phase of speed skating, and analyzes the change feature of muscle strength, so as to find out the reasons of less power output and provide reference for training and the improvement of sports results.

摘 要：为了找出使用新冰刀后蹬冰时下肢三关节肌群的生物力学特性，首次利用数值计算中的牛顿插值法，将等动测试获得的动力学数据和三维立体解析获得的运动学数据结合，绘出两名优秀女子速滑运动员实际蹬冰时肌群力矩的变化曲线，并分析肌力变化特点，找出两人做功明显不足的原因，为指导训练和提高运动成绩提供定量依据。

A method of character structure analysis is proposed to analyze regional feature and orientation relation feature of calligraphic character. Based on these features the orientation relation function is used to extract structure information and we can get the writing order of each part of a character based on the normal writing rules of Chinese character.

Besides expressing design result, it provides domain constraint for design process and model information for digital assembly sequence planning and simulation of stamping die, which is usually ignored in the former product models. Taking the specific structure and design process of stamping die into account, the information of workpiece is composed in die product model as product feature. Former product models merely contain mainly about the die design result, this model extends the contents of product model with the relation feature of the composed subassembly and parts and also other associated production knowledge. It is convenient for getting the associated information during intelligentized design process.

该模型不但能完整地表达冲模的设计结果，同时还表达和存储了冲模设计的知识信息，能较好地为冲模的设计过程提供规则和约束，支持产品的智能设计过程以及冲模的数字化预装配规划和仿真；而模型中冲压件信息的集成则扩大了冲模产品模型的信息内涵和应用外延，便于建立冲模智能设计过程的信息关联，从而使集成信息模型成为产品设计过程上、下游活动实现信息共享的基础。

In relation to the feature extracting, the first step is to extract the "simple" surfaces such as planes, natural quadric surfaces and tori. Planes considered as degenerated quadric surfaces, the quadric surface feature extracting should be more important in RE.

而在点云的特征提取中，首先提取的是包括平面、自然二次曲面(包括球面、圆柱面、圆锥面)和圆环面的"简单"曲面，我们认为平面是一种退化了的二次曲面，因此研究二次曲面特征的提取是其中首要的课题。
