快速成形技术中轮廓环的分组算法及其应用

以平面内轮廓环的存在规则和相互关系为出发点，提出了一种简单实用的轮廓环的分组算法，通过本方法对平面的轮廓环进行分组，能够把一个平面分解成一系列简单的单连通区域，分组后的轮廓环不仅能够在进行其他运算时减少重复计算，而且可以在分区填充扫描线时减少分区数，从而减少实际扫描时的空跳．     

基于遗传算法的层合板结构的可靠性优化设计

采用遗传算法分析了存在初始缺陷的复合材料层合板的可靠性优化问题．优化设计时，以层合板结构的厚度最小为目标函数，以可靠度要求为约束条件．在可靠度分析中，取初始缺陷、强度参数、单元层的厚度为随机变量，采用一阶矩法和Tsai-Wu准则分析每个单元层的失效概率，系统失效概率的计算基于串联系统假定．通过比较遗传算法与序列二次规划法的计算结果，证实了遗传算法用于可靠性优化设计的有效性．

根据渣油热裂解反应的规律及单事件方法的基本原理，以延迟焦化为背景，将2，5—二甲基—壬烷作为模型化合物，介绍了如何通过使用布尔邻接矩阵和辅助向量来表示分子结构及分子的热裂解反应，并在此基础上建立单分子的主反应网络。结果表明：单事件方法在计算机上建立单分子的主反应网络是快速而有效的，进而为建立分子尺度的延迟焦化反应动力学模型奠定了基础。     

刑法罪过的心理学分析

通过对各国罪过理论的比较分析,发现在罪过研究中普遍忽略了情绪因素,而且各国对不同种类罪过的非难重点差异也较大。如果剥离罪过中的法律因素,剩下的主要就是心理内容,由此对罪过进行心理学的分析,在第一层面即罪过的共性中得出罪过的心理内容是知和情意的结论,使情绪有所依归;然后,对罪过的第二层面即罪过内部成分的组合方式进行深入考察,得出在刑法罪过中,知是基础,情意是主导,情意承载着刑法责任与非难的结论。最后,将我国的罪过放到知与情意所罗织的网络(模型)之中,发现疏忽大意的过失其实也存在着情意因素,并得出犯罪过失其实是情意的缺陷而非注意的缺陷的结论。

Robot Calibration Using Active Vision-based Measurement

This paper presents an efficient robot calibration method with non-contact vision metrology. Using the coplanar pattern to calibrate camera made the active-vision-based end-effector pose measurement be a feasible and cost-effective way. Kinematic parameter errors were linearized and identified through two-step procedure, thus the singular and non-linear condition was overcome. These errors were then compensated using inverse model method. The whole calibration process is flexible, easy to implement and prevents the error propagation from the earlier stages to the later ones. Calibration was performed on MOTOMAN SV3 industrial robot. Experiment results show that the proposed method is easy to setup and with satisfactory accuracy.     

A Study on the Surface Structures of Viscose-based Activated Carbon Fiber by FT-IR Spectroscopy and XPS

Using viscose fiber (VF) as starting material and common steam as activating agent, formation of oxygen structures in activated carbon fiber is investigated. In the preparation of samples, VF was first heated at temperatures between 450℃ and 900℃ in N_2 artmosphere. Then, in a successive activation stage, the product carbonized at 600℃ was activated in steam at 450-900℃ for 30 min, and at 600℃ for 5-30 min. The other carbonization products were activated at 600 and 900℃ for 30 min respectively. The products activated at 900℃ were then activated at 450℃ for 30 min again. The starting materiah carbonized products and all activation products were examined by FT-IR spectroscopy and some products were examined by X-ray photoelectron spectroscope (XPS). And the yields of the carbonized and activated products were calculated. By analysing these spectra, the amount of oxygen-containing functional groups of the activated products attained under various activation time, various activation temperature and     

Switched Capacitor Network Analysis by Means of TCM

The totally coded method (TCM) reveals the same objective law, which governs the gain calculating for signal flow graph as Mason formula does. This algorithm is carried out merely in the domain of code operation. Based on pure code algorithm, it is more efficient because figure searching is no longer necessary. The code-series (CS), which are organized from node association table, have the holoinformation nature, so that both the content and the sign of each gain-term can be determined via the coded method. The principle of this method is obvious and it is suited for computer programming. The capability of the computeraided analysis for Switched Capacitor (SCN) can be enhanced.
