Application of CAD Techniques for Design of Packaging Paper Box

CAD techniques were applied to automated design of packaging paper box such as the performance and selection of box pattern, the structure computation, the art design(including sample design, the box sample unfolding and craft drawing), input and edition of Chinese characters and foreign words, and output of the drawings. A packaging paper box system is developed to automate the packaging paper box design processes.     

Application of CorelDRAW in Environmental Art Design

CorelDRAW has particular uses in architectural design, interior design and landscape design. By comparing several software, it was found that CorelDRAW had the working plan drawing of AutoCAD, mapping of 3DMAX, and better typesetting than Photoshop had, thus it plays an irreplaceable role in drawing working plan of environmental art design, especially colored plane and elevation view drawings.     

Analysis on the Claims Caused by the Defect of Contract

The engineering contract is composed of many documents between client and contractor, such as agreement, notification of award, tender and appendix to bid, conditions for particular application, instruction to bidders, technical specifications, design drawings and bill of quantities etc. Because of the limited time and money to prepare these documents, the defect is unavoidable. The defects include omittance, equivocalness, conflict and mistake. These defects often lead to claims.

Fast Animation Display of Large Structure with Multistep Modes

The method that the MASM assembler is interlaced to the MS-FORTRAM 5. 0 is used to store some step structural mode drawings in the designated disk file through their visiting VRAM,which are then restored in it when needed in order to realize the quick animation display of the mode. This method solves the problem of insufficient memories in storing multistep structural mode drowings with the ordinary method. As a functional modular of finite element analysis programs SAPS and ADINA transplanted to a microcomputer,the modular programed with the above method can quickly display the animation of large structure with multistep modes.     

COMPUTER AIDED DESIGN OF THE CORE AND CAVITY OF PLASTIC INJECTION MOULD

This paper discusses the designing of the injection mould for producing the plastic case of TV set carried out in the type IBM PC/XT (or Great Wall 0520)micro-eomputer. The procedure consists of inputting the 2-D drawings of the TV set case with the aid of sub-drawing, coding and menu specifying; setting up the mathematic model according to the relationship between the plastic part and the mould; designing the core and caving of the mould and finally displaying and plotting the drawing of the mould. The connection between the Auto CAD software and the advanced language for orogramming and the data convertion is also discussed.     

Introgression in maize

The principal characteristics of maize and its two relatives, teosinte and Tripsacum are described. The manifestations of the introgression of teosinte into maize determined from experimental cultures can be recognized in prehistoric maize from Guatemala, Mexico, and the southwestern United States. This introgression, which began at least 2,000 years ago, is still proceeding in Mexico where maize and teosinte commonly grow in the same fields and hybridize frequently. Evidence is presented of the direct introgression of Tripsacum in several races of maize of South America. The introgression of teosinte and Tripsacum has contributed to the evolution of maize through gene recombination, mutagenic effects, and various types of heterotic phenomena. The role of introgression in the improvement of maize is discussed.Presented at a conference entitled The role of introgressive hybridization in the evolution of crop plants and their wild relatives, held at Versailles on 4th January, 1961 by the Section Wild Species and Primitive Forms of Eucarpia (European Association for Research on Plant Breeding).The research reported in this paper was supported in part by a grant from the Rockefeller Foundation and the publication expenses were borne in part by the Maria Moors Cabot Foundation for Botanical Research. I am indebted to Dr. W. C. Galinat for several drawings and to Mr. S. M. Sehgal for the photographs in figure 14.     

苯磺隆、苄嘧磺隆对不同小麦品种安全性及叶绿素含量的影响

室内土壤滴浇法测定了苯磺隆、苄嘧磺隆对不同小麦品种的安全性和叶绿素含量的变化,结果表明：两种药剂对不同小麦品种的安全性存在较大差异,且对根长的抑制作用明显大于株高;对叶绿素含量的影响与对株高的影响结果一致。苯磺隆对周麦13的根和芽敏感,使用不当易产生药害;对偃师4110根长最安全,株高最敏感。苄嘧磺隆对高优503根长最安全,株高最敏感;对周麦13株高最安全,根长最敏感。因此,小麦田化学除草应根据不同小麦品种来选择除草剂品种、有效用量和最佳施药方法。

不同遮光胁迫对大豆生长发育进程及形态性状的影响

通过遮光处理,研究不同遮光强度及持续时间对大豆的生育进程和形态性状的影响,结果表明,大豆播种后遮光20%~50%,时间持续到V3期以后,大豆各生育阶段所需生育日数减少,生育期缩短。遮光20%时间持续到V3以后,遮光30%时间持续到R1以后,遮光50%时间持续到R5以后,大豆生育期显著或极显著缩短。同一遮光持续时间,遮光强度的加强会导致R5-R8生育日数增加,使大豆生育期(VE-R8)延长。遮光强度及遮光持续时间对大豆株高、子叶节高度、茎粗和主茎节数影响显著。遮光50%持续到R5期以后,植株形态由直立变成蔓生型。

施肥对春青稞干物质积累、分配及产量的影响

为研究施肥对青稞干物质积累、分配及产量的调节作用,以‘藏青27’、‘QTB13’和‘QTB25’为试验材料,比较分析不同施肥处理下干物质积累、分配及产量的变化规律。结果表明：增加施肥量促进青稞分蘖期—成熟期的干物质积累及开花期和成熟期干物质向营养器官和籽粒的分配,提高了花前营养器官贮藏同化物转运量及对籽粒贡献率,降低了花后同化物输入籽粒量对籽粒贡献率。‘QTB13’和‘QTB25’在F₂条件下,更有利于干物质积累及向营养器官和穗部的分配,花后同化物输入籽粒量最大,产量也最大。‘藏青27’在F₃条件下,更有利于干物质积累及向营养器官和穗部的分配,花后同化物输入籽粒量和对籽粒贡献率最大,产量也最大。说明合理施肥有利于青稞干物质积累分配及产量提高。

Rule of law,anti‐corruption,anti‐terrorism and militant Islam: Coping with threats to democratic pluralism and national unity in Indonesia

Abstract: President Yudhoyono, Indonesia's first directly elected president, was swept into office on a wave of popular support, but was faced with a formidable array of challenges, each demanding a prompt and effective response. Among the most immediately pressing, calling for crisis management, were: first, the need to assert political control and to build an effective political coalition; second, the need to secure grass‐roots democracy by ensuring that regional elections were effectively carried out; third, the need to cope with the Aceh tsunami crisis and achieve a peaceful reconciliation with the Free Aceh Movement; and fourth, the need to resolve a series of socioeconomic policy ‘growth versus equity’ dilemmas, to attract foreign investors to stimulate export‐led growth, while securing basic needs and anti‐poverty social programmes. After briefly noting how Yudhoyono and his administration responded to these immediate problems during its first 20 months in office (to June 2006), the paper then discusses at greater length three more fundamental and intractable sets of problems, namely, the urgent need to implement judicial and administrative reform, and to launch a wide‐ranging anti‐corruption campaign; the need to confront the resurgence of militant Islamic terrorism, both inter‐communal and al‐Qaeda‐inspired, and to mount a robust anti‐terrorist campaign; and finally the intense and convoluted problem of inter‐sectarian animosities, and the clash of religious versus secular values, the reconciliation of which will be absolutely critical to securing social stability, democratic pluralism, national unity and Indonesia's futurity.
