However , the patrilocal custom prohibits the mother - daughter contact but enforced in - laws encounters in their everyday living conditions . 2 ) many old women are financially dependent on their sons , which put them in a disadvantaged situation in the in - law dyadic relations ( 2 )经济依赖儿子的婆婆，使婆媳关系生成了地位的变化，婆婆吃老困难，可由必需以家事服务交换生活依赖及日常得看儿媳脸色反应出来，使婆婆生成以前要侍侯公婆，现在要侍侯媳妇的不平感受。
Such recognition algorithms the feature extraction based on a set of 2 - d gabor wavelet and computation of percentage mismatched bits hamming distance between a pair of iris representations developed by daugman , texture analysis methods developed by wildes and chinese academy of science , extraction of iris signatures by means of zero - crossing of the dyadic wavelet transform developed by boles and so on 深入研究了多种典型识别算法: daugman的基于2 - d复值gabor小波的虹膜相位编码和hamming距离的方法; wildes和中科院的基于虹膜纹理分析的方法; boles的基于小波过零检测的方法;上海交大的基于小波模极大值的方法等。并在此基础上,对虹膜识别系统中的图像预处理和识别的若干算法进行了改进。
Then the wavelet transform is introduced for the further analyzing . current singularities based on wavelet transform are analyzed . two kinds of wavelet transforms are firstly used to analyze the former two currents , one for continuous wavelet transform and the other for dyadic wavelet packet 在此基础上，论文使用传统的傅立叶分析方法对远方短路电流和机车起动电流的仿真值进行了分析，针对其存在的问题引入小波变换作为分析工具对两种电流进行进一步的分析。
In this paper , for the first time the modulus maximum pair of wavelet transform was used to detect otdr signals by detecting their singularity points . otdr signals were decomposed with a dyadic spline wavelet by mallat algorithm , all kinds of event points were recognized by analyzing the relationship between signal with points of event and the modulus maximum pairs of its wavelet transform 本文首次将小波变换模极大值对监测信号奇异点的理论应用于otdr信号，采用二进样条小波对otdr信号按mallat算法进行变换，分析含有事件点(故障点)的信号与其小波变换模极大值对的关系，对不同的事件点进行识别。
6 . based on wavelet coefficient distribution and a quantitative analysis on the magnitudes of wavelet coefficients , a new embedding strategy for watermarking is proposed based on dyadic discrete wavelet transform ( ddwt ) domain and multi _ band dwt domain ( mdwt ) respectively . it is claimed that different embedding formulae should be applied on the low frequency subband and high frequency subbands respectively 根据小波图象系数的分布特点和对小波系数振幅的定性、定量分析，分别提出了基于离散二进小波变换( ddwt )和基于离散多进小波变换( mdwt )的新的图象隐形水印嵌入对策；同时指出，水印嵌入到小波图象低频系数和高频系数需要用不同的嵌入公式。
The results were as follows : ( 1 ) the couple ' s motivation and commitment to therapy and the therapeutic alliance were the important therapeutic preconditions ; ( 2 ) the systematiclly therapeutic elements of change included prescribing a dyadic homework , reflecting the relational position , reflecting the interaction pattern , understanding and validating the couple ' s feelings , and marking the subsystem boundaries 治疗室内的系统性疗效因子则包括双人组的家庭作业、反映关系位置、反映行?互动模式、理解与认可双方的感受、划清次系统间的界限等。
