It is different according to study of the purpose , to select the rs data source with different scales , different space resolution , different wave bands making up and different times 根据研究目的不同，选取不同尺度、不同空间分辨率、不同波段组合、不同时相的遥感数据源。
According to the dynamic boundary conditions during walking , the corresponding mechanical analysis was performed for five typical phases in a gait cycle of the residual limb 根据行走过程中残肢与接受腔的动态边界条件，对残肢在一个步态周期内的5个典型步态时相进行了动态受力分析。
A lack of rainfall has affected water supplies for 9 . 8 million people and 9 . 1 million head of livestock , the beijing morning post said . both figures had doubled since early march 北京晨报指出，久旱不雨所造成的缺水，影响了约九百八十万人和九百一十万头家畜；这两个数字和三月初时相较，已增加了一倍。
So many merits of rs technology , such as the trends , macroscopic , receive and the image series of the same area etc , make it incomparable to traditional technological methods of land use / land cover 遥感技术的动态、宏观、及时以及能够得到同一区域不同时相的影像系列等优点，是传统土地利用覆盖动态调查技术所无法比拟的。
9 . the gonad development of g . przewalskii can be divided into 6 stages . the development of oocytes from phase 3 to phase 4 was synchronous , the histological structure of the ovary and testis came back to stage ii after reproduction 青海湖裸鲤的性腺发育可分为6期，卵母细胞从第3时相发育到第4时相基本同步，产后卵巢和精巢的组织学结构回复到期。
The research demonstrates that making use of the simulation apparatus the feature of the coronary artery blood stream changes with time can reappear and an experimental method for homodynamic research of coronary artery is presented 结果表明，该仿真装置能够在相当程度上复现冠状动脉血流时相性特征，为进一步研究冠状动脉血流动力学问题提供了一种实验手段。
( 5 ) based on the spectrum characteristic of the vary kinds of water , we expound the method to extraction them , improve the method of proportion estimation , put forward the best opportunity for extractioning the water of salt field 对水体提取方法? ?比率测算法进行算法改进，提出盐田水体提取的最佳时相，基于各种盐田水体的光谱特征，详细阐述它们各自的提取方法。
A relative radiometric correction algorithm based on least absolution deviation regression is also proposed in this dissertation , in which robust estimation and iteration method are used to eliminate the influence of change area 论文根据不同时相图像的灰度统计关系,提出了一种基于最小偏差回归的相对辐射校正算法,通过稳健性估计和迭代处理减少了变化区域对辐射校正的影响。
By analyzing multi - temporal remote sensing images about same region , change detection is used to provide land change information for updating data of resource and environment , analysising the situation of battlefield and evaluating the affection of attack 通过分析同一地域不同时相的遥感图像,变化检测提供地物发生变化的信息,用于资源环境数据更新及利用、战场态势分析以及毁伤效果评估等。
It is showed that the torque ripple is not only connected with the phase currents , but also with the other factors , such as the instantaneous phase emf ' s in the case of commutation , the angle of commutation and the parameters of the windings 从一个新的角度分析了绕组换相引起转矩波动的原因，指出换相转矩波动不仅与电机绕组电流有关，还与换相时相绕组感生电势瞬时值、换相位置角、绕组参数等因素有关。
