连续变量不稳定型一阶差分方程的振动性 - Several key technology is particular expatiated in the paper such as eliminating the queer data by one rank difference method , the arithmetic of drawing a roundness with lattice liquid crystal , designing the iir digital filter , auto changing measure scale and software dependability design technique
本文详细阐述了几个关键技术：一阶差分法剔除奇异项，点阵液晶的作圆算法、 iir数字滤波器的设计、自动量程转换和系统的软件可靠性设计等。 - This dissertation focuses on the application of data fusion in two - phase flow regime identification . following is the main contribution of the dissertation . 1 ) based on quartile and first order differential , a new outlier detection algorithm is presented , experiments show that the method combining with low pass filter can remove gross error and unwanted frequency components
本文的主要工作与创新点在于： 1 )将分位数方法与一阶差分法相结合，提出了一种基于一阶差分的粗差剔除方法，该方法与低通滤波器的结合可以有效去除两相流压力波动信号中的粗大误差以及信号频带以外的频率成分。 - At the meantime , during the procedure of pre - processing , according to the character that the illumination conditions on the scene of the expressway toll collection frequently change a lot , the algorithm of first difference combining the method of fixing the threshold of binarization via accumulating the points was used to complete the job of extracting the outline of the image
