查询词典 system engineering

In the whole market development, there are also a lot of places: 1、decoration personnel, decentralization, spare no good management system, not by most decoration of professional training and lack of effective knowledge in the cases of housing decoration, the quality of the crisis, cut corners, crude abuse of engineering quality is low, no guarantee after-sale, etc. 2、in the industry, many designers unspoken rules, and for his own benefit subcontracted, the owner of this link purchase materials, a rake-off extraction. 3、decoration materials, the source of confusion, very small workshop of small companies selling certificates of poor quality material, often without the use of security, and short, etc.

在整个市场的发展中，也存在很多不规范的地方：1、装修人员的业余化，分散化，没有良好的管理系统，打多数装修人员没有受到过良好的专业培训，在缺乏有效的知识的情况下，往往对住房的装修质量带来不小的影响，偷工减料，粗制滥共工程质量低下，售后无保障等等。2、行业中潜规则，不少的设计师和施工者，为了自身的利益，在业主购买材料的这一环节中，提取着回扣。3、装修材料的来源非常混乱，小作坊，无证件的小商家兜售的材料，往往质量差，无保障，使用年限短等等。

First, the effects of magnetic RAM relaxation time and the rise-time of incident pulse signal on reflection signal are discussed, the relationship between the rise-time of incident pulse and relaxation time based on the energy of reflection signal is revealed. Then, the effects of magnetic hysteric, susceptibilities and saturation upon reflection signal are analyzed, the results reveal the reflection of RAM target and UWB signal design. In the meantime, dielectric relaxation time effect about dielectric RAM target is analyzed simply, and the effects of relaxation time and the width of incident pulse upon reflection signal are probed. Finally, a few RAM targets are measured in the chamber using the impulse radar experiment system which is developed by the team of anti-stealth impulse radar on Department of Electrical Engineering, National University of Defense Technology. The experimental results show the similarity of the rule of echos with the theory. From the compared results of different tagets, we concluded, compared with 15% wideband sinusoidal signal, the impulse signal has increased 10～12dB energy from the same loaded RAM target; this, in turn, shows the nonlinear effects of RAM to the echoes, and the potentiality of the impulse signal to RAM targets.

首先分析了磁性RAM的弛豫时间及入射脉冲信号的上升时间对反射信号的影响，从反射信号能量角度出发，给出了入射脉冲上升时间与弛豫时间的关系；接着分析了磁性RAM的磁滞特性、磁化率及磁化强度对反射信号的影响，给出了RAM目标辐射和有关UWB信号设计的一般性结论；其次，对介电RAM的弛豫时间效应作了简单的分析，探讨了介电弛豫时间及入射脉冲宽度对反射信号的影响；最后利用国防科技大学电子技术系&反隐身冲激雷达技术研究组&研制的冲激雷达实验系统，在微波暗室中对几种不同的RAM目标进行了测量，结果表明：其反射波形的基本规律与上述理论分析相一致；从各种不同目标回波的能量对比结果得出，涂覆RAM目标对冲激信号的吸收比15％带宽的正弦信号要小10～12dB，证实了RAM的非线性效应对回波的影响，也证实了冲激信号反隐身的潜力。
