均方振幅 meaning in English

mean square amplitude

Therefore the dynamical characteristic is acted as detected parameter for fractured detection ( primary amplitude secondary frequence ) . and the amplitude of mean sguare and central frequence are acted as evaluational parameter , based on the those studies , the new ideas is put forward that fractured azimuth is dected by lateral difference and fractured density is dected by vertical difference for three facters of fracture , wavelet acted as analysis tool and direction by wave field characteristic applied the multiple scale edge dectection and self - adaptive edge detection into the detection theory of seismic fractured azimuth , also put forward the wavelet different scale filter method of the fractured azimuth detection
因而，确定了主要以振幅，其次是频率的地震波动力学特征作为裂缝检测的被检参数和均方振幅和中心频率作为检验检测结果正确与否的评价参数。在上述研究基础上，针对裂缝的三要素，提出通过横向求异检测裂缝方位和纵向求异检测裂缝密度的新思想。并以小波作为分析工具，以潜山波场特征作指导，将数字图像处理中的多尺度边缘检测和自适性边缘检测引用到地震裂缝方位检测中来，并提出了小波变尺度滤波法新的裂缝方位检测法。
