missile engine造句

• Weak flaw detection of missile engine composite structure based on wavelet spectrum
  基于小波谱分析的导弹发动机复合材料深层缺陷检测
• Deep flaw information in missile engine composite structure is very weak and its echoes overlap badly in time field and frequency field , which lead to the difficulty in information abstraction
  摘要导弹发动机深层信息非常微弱，而且多次回波的时域频域严重重叠，信息提取难。
• In this paper ultrasonic model of missile engine composite structure is set up and the optimal time window is selected to model , at last it can detect deep flaw in composite structure with the technology of wavelet - spectrum successfully
  通过系统响应的角度，对导弹发动机部位复合结构材料的超声信号进行建模，利用最优时间段截取分析建模，采用小波谱分析技术对导弹深层缺陷进行成功的识别。
• By use of some eigenvalues such as missile launch location , infrared radiation of boosting missiles plumes and missile engine off - time eigenvalue , data fusion based on weight sum of membership degree is applied to deduce the type and launching country of the missile
  该算法提出用导弹发射点，位置、导弹尾焰红外特徵和导弹关机点特徵量作为导弹目标识别的特徵量，用模糊隶属度加权求和方式进行信息融合，根据融合和最大融合量的阈值判决确定导弹的类型、国别。
• Carbon fiber reinforced plastics ( cfrp ) are widely used in aerospace , marine engineering ( such as all kinds of stratigic missile engine shells ) and various civil applications due to their exceptionally high specific strength and specific module , good high - temperature resistance , corrosion resistance and so on
