Experimental study is practiced to examine AWJ cutting quality.By changing waterjet pressure and cutting speed,cutting kerf surface quality is studied.By the analysis of AWJ cutting mechanism and cutting process,the thesis explores the specific shape of the cutting section and its mechanism,and believes that the asymmetric distribution of abrasive jet's kinetic energy and jet's deflexion causing the formation of striations,waviness and cuspidate end.However,high-efficient cutting of AWJ could be achieved by...

对磨料水射流的切割质量进行了试验研究,通过改变水射流压力、切割进给速度来研究切割断面质量,对AWJ切割机理和切割过程进行了分析,探讨了AWJ切割断面的形貌特征及其形成机理,认为是射流断面磨料动能的分布不均和射流的偏转滞后造成了AWJ切割断面斜条纹和曲线及尖角处的尖端,提出了两种提高磨料水射流切割质量的方法。

According to the shortage of only considering the phase change of emitter and no refer to the amplitude change, based on the patterns of radar and decoy, using equal phase gradient method, while considering the influence about waviness of phase and amplitude of each, the decoying formula of the coherent decoy system is deduced, a damage probability model is drawn out.

针对目前多点源诱偏效果评估过程中,仅考虑各点源相位分量变化,未考虑幅度分量在空中变化的不足,基于雷达和诱饵的具体方向图,运用等相位面梯度分析法,同时考虑各点源辐射信号的相位和幅度波动的影响,对相参多诱饵系统的诱偏误差公式进行了推导。

For meeting the needs of automated real-time dynamic monitoring of heavy fog events by means of a weather satellite remote-sensing technique for specialized meteorological services like military operations and highway traffic, the paper presents a systematic study of spectral characteristics of visible and infra red light, the textures and dynamic dispersals of fogs on satellite imagery in the context of theory on the transmission of atmospheric radiation, thereby revealing their abruptness, waviness and mass-like features, which, in combination with a synthetic technique for cloud/fog maps of multi-channel remote-sensing spectra are used to set up a model for automatic separation of fogs from clouds based on the integrative application of spectral features and texture structures, for which are constructed corresponding discfiminant functions and criteria, and on this basis prepared is a"system for remotely-sensing monitoring of low cloud and heavy fog"which has been used for tests, with the main conclusions shown as follows.

本文针对军事和高速公路等专业气象服务中应用气象卫星遥感技术对大雾进行自动化实时动态监测的实际需要,从大气辐射传输理论入手,系统地研究了气象卫星遥感图像上云雾的可见光和红外光谱特征、纹理结构特征和大雾的消散动态特征,揭示了雾的突发性、波动性和团状雾特性,通过研究多通道遥感光谱的云雾图像合成技术,建立了综合应用光谱特征和纹理结构特征的云雾自动分离模型,给出了相应的判别函数和判别准则,研制了&低云大雾遥感监测系统&,并进行了实际应用试验。
