" if you hit this target successfully you have hit the achilles " heel of the virus , " said rolf hilgenfeld of the university of luebeck in germany , who led the study 德国吕贝克医科大学的罗尔夫希尔根菲尔德是主持该项研究的科学家，他说： "如果能够成功攻克这个课题，我们也就找到了非典病毒的致命弱点。
We use network interface detection in host agent , which will enable the ids work on switch network fine . first we analyze development state of intrusion detection system and study technology of intrusion detection system 在主机代理中的网络接口检测功能，有效地解决了未来交换式网络中入侵检测系统无法检测的致命弱点。
Compared with the nuclear - powered submarine , conventional submarine has standout merits of simple structure , lower expenditure of manufacture and maintenance . but some fatal failings such as high exposure probability and low durability also exist 与核动力潜艇相比，常规潜艇具有结构简单，造价及维护费用低等突出优点，但也存在着易暴露目标和自持能力有限等致命弱点。
In the research of the project of multi - user vehicle software radio cooperating with a company in guizhou , the thesis analyzes firstly the characteristics of wire transmission that the co - worker applied in the previous phase . aiming at the vital weakness , the thesis proposes a substitute plan which adopts wireless time divided multiple use software radio communication system to meet the demands of multi - user accessing channel and high flexibility 在与贵州某单位合作的多用户车载软件无线电台项目中,本文首先分析了合作方前期使用的有线传输方案的特点,针对其机动性差的致命弱点,提出了一种采用无线时分复用的软件无线电通信系统替代方案,以满足其多用户复用信道及高机动性的要求。
However , the traditional dc motor uses brush so as to switch the phases , so there are relative mechanical frictions . then it comes out many fatal failing , such as yawp , spark , wireless disturb , etc . what " s more , its making cost is high , its maintain is also difficult , therefore its application is greatly limited 直流电动机具有运行效率高和调速性能好等诸多优点，但传统的直流电动机均采用电刷，以机械方法换向，因而存在相对的机械摩擦，由此带来了噪声、火花、无线电干扰以及寿命短等致命弱点，再加上制造成本高及维修困难等缺点，从而大大地限制了它的应用范围。
Three - dimensionally braided structural composites have distinct structure that is fully integrated , continuously spatial fiber - network impregnated with ductile material . the new innovative materials have not plies as conventional composites have , and put an end once and all to low interlaminar strength showing in laminate materials . because of their enhanced stiffness and strength in the thickness direction , near - net - shape design and manufacturing , superior damage tolerance and specified aerospace function , the braided composites are gaining more and more attention of industry and academia 三维编织结构复合材料是完全整体、连续、多向的纺线(纤维束)的网络，充填以延性材料，这类新材料已失去通常复合材料的层合板概念，由此，层合板复合材料层间脆弱的致命弱点在编织结构复合材料中得到克服，所以编织结构复合材料具有高的强度和刚度(包括在厚度方向) ，接近实际形状的制造，高的冲击韧性、高的损伤阻抗，和按实际设计要求的特定的航空航天方面的使用功能，因而广泛地受到工业界和学术界的关注。
