集成系统中工艺卡片填写与工序图绘制的研究

利用VBA实现CAD和CAPP系统集成，讨论了基于Word平台进行工艺卡填写，并在此基础上进行工艺卡填写和工序图并行输出的一般问题。工艺文件的填写是在CAPP数据库的支持下，直接读取CAD所提供的CAPP工艺数据文件，经推理机推理自动生产工艺过程；工序图绘制是在特征图表级和参数化绘图原理的基础上进行的。     

Study of an identity

We solve the word problem of the identity x(yz) = (xy)(yz) by investigating a certain group describing the geometry of that identity. We also construct a concrete realization of the one-generated free algebra relative to the above identity. Received March 23, 2001; accepted in final form July 6, 2002.     

Differential Pulse Polarographic Determination of Nitrate in AUT Solution

A differential pulse polarographic method for the determination of nitrate ion has been developed. With 0.5 M CaCl₂ as supporting electrolyte, NO^?₃ is reduced to give a peak with E_1/2=–1.836 Volt vs. the Ag/AgCl electrode. The differential pulse polarographic peak height is proportional to the nitrate concentration from 20 to 60 ppm. The detection limit for nitrate is 2 ppm in pure aqueous solution. In the determination of 40 ppm nitrate a relative precision (relative standard deviation) of less than 2% was achieved. Nitrite interferes seriously and should be absent if accurate results are required. The method has been applied to the determination of nitrate in Ammonium Uranyl Tricarbonate (AUT) Solution, results obtained by this method are compared to those obtained by ion chromatography. The agreement between the two sets of results suggests that the DPP method can be used with a fair degree of confidence.     

Auto CAD实用技巧

利用Word自动化服务器实现基于模板的文书打印

介绍了一种可以利用Word的强大排版打印功能的模板文书打印方法，Word作为服务器而应用软件作为客户．用于打印的模板文件只是一个原始文件而不是最终文件，需要应用软件根据实际需要对它进行若干替换项的查找替换然后生成最终文书，而查找替换的实现者也是Word．     

大学英语教学中设置词汇课的设想

长期以来大学英语教学中,词汇教学始终没有受到足够的重视。本文从大学英语教学的终期目标的实际出发,不仅阐述了在大学英语教学中设置词汇课的必要性,而且提出了具体设想以及这一设想的实现对大学英语教学将会产生的积极作用。     

英译汉中的词义探讨

英语词义的复杂性有着多方面、多层次的表现。要在英译汉过程中正确地理解词义,就必须借助于词典,通过认真分析上下文,并仔细揣摩用词者的感情、态度和意图等因素,达到对原文的准确把握,再以贴切、自然、功能对等的译语表达出来,从而得到好的译文。     

南非世界杯足球赛参赛运动员年龄与身体形态特征统计分析

利用文献资料、数据统计和比较分析等方法,从数据平均值特征、位置结构特征和地域分布特征3个维度对2010年南非世界杯足球赛决赛阶段736名参赛运动员年龄、身高、体质量和克托莱指数4个指标进行统计比较研究.结果表明:32支队伍参赛队员平均年龄、身高、体质量和克托莱指数分别为27.2岁,181.7cm,76.1kg,418.8;非洲、美洲、欧洲和亚洲各个球队门将、后卫队员、中场队员和前锋队员在年龄、身高、体质量和克托莱指数上存在一定的差异.     

Enhancement in age hardenability of sintered Ti–5Fe alloy by Zr addition processed by pulsed electric current sintering

The age-hardenable Ti–5Fe–5Zr (wt. %, 5Zr) alloy has been consolidated by pulsed electric current sintering, following a β solution treatment, and the results are compared with a Ti–5Fe (0Zr) alloy. The precipitation sequence measured at 640°C ageing is β?+?athermal ω?→?β?+?isothermal ω?→?β?+?α. At the peak hardness isothermal ω phase forms at 20?s of ageing. The Zr addition retards the precipitation kinetics of the α phase; as a result, the α phase nucleates at latest at 300?s ageing in the overaged state. Fe is partitioned into β, while it is depleted from the α phases. There is Zr enrichment near the α/β interface when the α phase precipitates due to a solute drag effect; the growth rate of the α phase in the 5Zr alloy is significantly reduced compared with that in the 0Zr alloy.     

利用VBA实现表格的自动填写

在工作中,需要从Excel表中遴选出所需要的数据填写Word文档,若用人工方法,工作效率低,工作强度大,而利用VBA语言自动分割数据,可自动完成工作,提高工作效率,降低工作强度。
