• The role of symmetry analysis in teaching of electromagnetism is clarified systematically , and a logically clear teaching procedure for relevant contents is proposed . the application of mirror symmetry is emphasized
  摘要较系统地阐明了对称性分析在电磁学中的地位，并针对相应的教学内容提出了一种逻辑明晰的教学思路。文中着重强调了镜象对称性的应用。
• By adopting fta ( fault tree analysis ) and minimal path sets theory , the fault information stream analysis of spc - 33 digital governor is made , and from the point of system the ft is constructed . and the fault model with logic matrix in mirror symmetry has been built
  本文运用fta故障树分析方法和最小路集方法，对spc - 33电子调速器进行故障信息流分析，从系统化角度构筑ft ，并建立镜像对称的故障逻辑矩阵模型。
• There are three main reasons attributed to this result as follows : firstly , i choose a wavelet transform named fivezhu wavelet < , which is different the other wavelets from the fact that fivezghu wavelet have seven 7 sample points and was decomposed a orthogonal , two - band filter bank and include a detailed part ; which can be realized by two orthogonal mirror symmetries lattice filter
  为此我主要做了以下方面的工作：首先，是小波基的选取，因为小波基的选取不同于短时fourier变换。选取不同的小波基对同一图像信号处理会得到不同的结果，就目前的几种小波基。我选择了五株形小波。
• Because of phase information ' s stability and significance , this method is fairly robust , that is , it is invariant to illumination , contrast , and rotation . it can detect mirror symmetry , rotating symmetry and curve symmetry simultaneously . and it does n ' t need any preprocessing , such as segmentation
  由于相位信息的稳定性和重要性，该方法具有很强的鲁棒性，不受图像亮度、对比度和旋转的影响；它能同时检测镜像对称性、旋转对称性和曲线对称性，不需要图像分割等任何预处理。
• The spectral analysis of non - orthogonal functions cannot be obtained by orthogonal integration method . only the spectral analysis of some particular non - orthogonal functions can be realized by integral transformation . thus , the concept of reflection matrix is proposed and the mirror symmetry of spectral analysis for non - orthogonal function is revealed . any element functions whose reflection matrix can be obtained possesses its inverse element function . the spectral vector corresponding to an element function possesses its inverse spectral vector corresponding to the inverse element function . by reflection matrix the mapping relation of element function pair and spectral vector pair can be established . spectral analysis of non - orthogonal functions can be obtained with this symmetry by using the integration method as in the case of orthogonal functions , instead of calculating the inverse matrix as usual . so a convenient and practical method for spectral analysis of non - orthogonal functions is offered
  非正交函数不能利用正交积分来实现谱分解.仅有某些特殊的非正交函数可以通过积分变换实现谱分解.本文提出了反射阵的概念,揭示了非正交函数谱分析的镜像对称性.任何能够建立起反射阵的元函数存在着它的逆元函数,并且任何基于该元函数的谱向量同时也存在着基于逆元函数的逆谱向量.元函数对与谱向量对通过反射阵建立映射关系.利用这种对称性,非正交函数可以象正交函数一样使用积分方法获得谱分解结果,而不必使用求解逆阵的方法,从而为非正交函数的谱分解提供了便捷、实用的方法
