In the end , a new reliale indicator , energy peak , is found to used to estimate damage . its three parameter : peak time , peak frequence and peak power are also evaluated . this study improves monitoring equipment in intelligence , low power dissipation and security 作者最后利用脊髓在受不同程度损伤下的脊髓诱发电位的时频分布图，比较时频分布和时域上的各参数的变化，找到了新的损伤判定的特征指标：峰值能量,及其三个参数:峰值时间、峰值频率和峰值功率。
The frequence and modal of main stream piping were analysed under the condition of different velocity of stream and the valve taken as the centralizing mass . this paper also gives the responses of steady state under the condition that the frequency of forced vibration is 4hz 、 8hz 、 12hz respectively 将阀门作为集中质量处理，分析计算不同蒸汽流速下，某汽轮机主蒸汽管道系统的振动频率和振型，并给出了激振力频率分别为4hz 、 8hz 、 12hz时该管道系统的稳态响应。
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。
Third , mensurated the front axle ' s load - time history when truck was running on general tar - paved roads , mountainous roads and the proving ground enhancement roads , second sampled and pretreated to the load - time history with rpc software of mts corporation , acquired the relationship of the frequence of the mean and amplitude load , obtained the zero mean equivalent loads using goodman experiential fatigue equation , acquired the weibull distributing functions of equivalent loads of respective roads 第三，测定了汽车前桥在一般沥青公路、山区公路和试验场强化试验路面的载荷时间历程。对载荷时间历程进行了二次采样和数据预处理。采用雨流计数法得到了各路面的载荷均、幅值的频次关系，并根据goodman经验疲劳公式，得到了零均值的等效载荷及相应的频次。
According to the statistical characteristic of noun phrases , we used an iterative re - evaluation algorithm for high - frequency noun phrases , and our metdhod for low - frequence noun phrases is similar to the algorithm for low - frequence content word . this method can take into account the alignment information on the whole , and acquire the result with high coverage rate 名词短语的对应。本文根据名词短语的统计特征，对高频名词短语采用迭代重估算法；对低频短语，则采用类似于低频实词的对应方法。这样就能够从整体上把握对应信息，并使结果具有很高的覆盖率。
