In this paper, the measurements on the output of detonator at the domestic and foreign research filed is analyzed.

通过对国内外雷管输出威力测量技术的研究现状进行分析，在现有的油压应变测试系统的基础上，对油压应变测试系统进行了改进，并利用改进后的油压应变测试系统对多种雷管进行了输出威力测试，获得了一些雷管输出威力的数据，并提出了雷管输出威力合格判据的方法；为方便火工品信息的有效管理，利用Visual Basic6.0和Access建立了火工品数据库系统，系统能够对火工品各种信息进行有效的管理，具有数据添加、查询、修改、删除等功能。

The analysis of simulation result indicates that the CDMA system has much more superior performance on noise-immune; the continuous processing in the part of signal modulation can not improve the efficiency of spectrum in CDMA system; under the situation , making sure that the proximity of the reliability of information transmission to the unsmoothed system, the power of the transmission can decline to 90.5% of the unsmoothed system, the bandwidth of -50dB will decline to almost one half of the unsmoothed system in spread spectrum and dispread spectrum by using continuous WALSH codes.

仿真及分析结果表明：CDMA系统具有更优越的抗噪声性能；信息调制部分的平滑化处理在CDMA系统中不会改善频谱的利用效率；运用平滑化WALSH码进行扩频和解扩时，在保证信息传输可靠性与非平滑化系统接近的情况下，能够将发射功率降低到非平滑化系统的90.5%，-50dB带宽减小到非平滑化系统的一半左右，这有利于降低对临近频段的干扰，提高频谱的利用效率。

With along the progressive application of computers ,we excogitate this management information system of students in order to make the mansgement of school modern and scientific and assure the disposal of information instant and exact,and we manage the information of students by computers.

摘要学生信息管理系统是一个教育单位不可缺少的部分，随着计算机应用的日益广泛，为提高学校管理工作的现代化、科学化水平，为保证信息处理的即时化、准确化，我们开发了学生信息管理系统，使用计算机对学生信息进行管理。

Ever since the 1970s, the contents related to soil resource have already expanded largely, they have began to serve for agriculture, industry, city planning and military service synthetically and people have began to regard soil resource as the conjunct results of geosphere, atmosphere, hydrosphere and biosphere.

由于土壤信息系统能够为用户提供准确、及时的土壤信息和相关信息，在全球土壤变化研究中这种技术的应用是不可避免的，同时为了准确评估土地生产力，及时监测土地质量的变化及建立全球变化模式，迫切需要建立和改善土壤信息系统。

Aimed at how to apply the theory of knowledge organization to software design and development, this paper analyzes the limits and difficulties of traditional document information management system in supporting to KOS. It emphasizes the ideal of Multi-MARC which construct the union mechanism to describe different type document and supprot KOS integrate with document information management system. It also introduces the effect on software development.

针对如何将知识组织的理论应用于软件系统的设计与开发，分析传统文献信息系统在知识组织系统支持方面的局限和困难，着重介绍Multi-MARC架构统一的知识描述机制的思想，通过为各种不同类型的对象建立相同的描述机制，实现知识组织系统融入文献信息管理系统，最后介绍在软件开发方面的影响。

The paper presents a seheme for long-distance transmission of the informations of primary radar-video, antenna angle, various telecontrol, telemetering and telemonitoring by means of the microwave communication apparatus.

本文给出了用微波设备远距离传递雷达原始视频信息、天线方位信息和各种遥测、遥控、遥监信息的方案；详细地讨论了方位信息的传递；提出了一种简单而可靠的容错编码系统和解码系统，对其抗差错能力进行了估算，并探讨了抗差错能力与天线转数、发射重复频率之间的关系。

Finally, we design a series of module and system testing. From the result of these testing, we get the conclusion: in our Centrifuge Experiment System which is based on Wireless Optical Communication and Electrical Slip Ring, both data and power can be transmitted well between the stator and the rotor of Centrifuge, So the validity of our design can be proved.

最后，本课题设计了充分的实验，分别从功能模块和系统的角度，对本无线光传输系统和能量传输系统进行了测试，从测试结果可以看出：在以无线光传输作为信息传输方式和以导电滑环作为能量传输方式的离心机系统中，无论是信息传递，还是能量传递，均能满足系统的设计性能指标，由此证明了本论文研究工作的正确性和有效性。

This paper introduces an email- autosending subs ystem, which sends the latest abstract information in the query database to rele vant employees by email at the specified time as well as providing hyperlinks to the query database. It is incorporated into the Intranet-based Information Quer y System.

在企业Intranet上原有的信息查询系统中增加一个电子邮件自动发送系统，该系统可以定时地给企业员工在Intranet上的电子信箱发送查询系统数据库中的最新信息的摘要内容，并提供一个超链接使员工可以很方便地连结到查询系统。

While the governor make use of the GIS information system's assistance management and analyze with the determination, it can develop the scientific of the work, the normal levels, making use of every kind of information efficiently, increasing inspectional speed in search, promote the information shares.

据统计，现代化社会信息系统中有百分之八十五以上的数据均有地理属性，MapInfo 地图信息系统用地图、图形和图表等信息描述形势，通过对数据库的查询、操纵来实现对各类信息的分析处理，可以将结果清晰的，以地域分布或图表的形式显示出来。

In the chapter 5, we make our experiments in the process of Record libratory management system , one part of the whole zheJiang TV Statation MIS. We do requirement analysis and extract the business rule information, and then apply MIS-AD system to construct the Model Information Library. Meanwhile, we put forward that how to develop the program in client side. Finally, we compare our system with the traditional system and bring forward the difference between them.

本文第五章对浙江省电视台综合信息处理系统中磁带库管理子系统的业务流程进行需求分析，并抽取业务规则信息，使用MIS-AD系统建立它的模型信息库；同时指出在系统实际开发过程中，如何基于MIS-AD来开发客户端程序；最后我们对比了基于MIS-AD开发的系统和传统的MIS系统的之间的差异。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.
