数据利用 meaning in English
data utilization
Examples
- The data both surveyed uses navigation software to record in the database display on the navigation map in computer automatically , and draw out the real navigation course
两者所测出的数据利用导航同步观测软件自动记录显示在计算机的导航图上，同时自动存储在数据库中。 - In short , vector data take the simplest topological entities - points , lines , and polygons - and anchor them within a 2 - d cartesian coordinate system to describe geographical features
简言之，矢量数据利用最简单的拓扑实体点、线和多边形，并在二维笛卡尔坐标系统中固定它们来描述地理特征。 - The data of whole system is processed by wavelets and keepcd into data base . then this system adopts frontal reasoning based on fault tree and fuzzy technology to realize fuzzy reasoning to diagnose whether the system has or will produce fault
整个系统所采集的数据利用小波分析的方法进行数据预处理，存入数据库，再采用基于故障树的正向推理方式和模糊技术相结合进行模糊推理来诊断系统是否已经或即将发生故障。 - So we can complete the kinematic analysis of the cam mechanism by the analysis of the corresponding assur - group . based on the method , this paper deals with plannar disc - cam mechanisms with different types of followers . the main points of this paper are as follows
基于杆组的分析方法，本文围绕各种类型从动件的平面盘形凸轮机构做了如下工作： 1 .根据凸轮机构的检测数据利用三次周期样条函数插值法对凸轮实际廓线进行曲线拟合。 - Due to the short distance among the planes which fly in a group , the conventional low resolution radar can not distinguish them in both distance and azimuth ? if we use the technology of isar to resolve the difference among doppler frequency of the targets and obtain a fine resolution cross - cross image , we may separate them , but a long time of coherent processing is needed < , for the formation targets , it can be approximately divided to rigid body and nonrigid body , so for the formation targets , that can be regarded as rigid which has a relative position and an identical movement , can be approximately considered as a large target , and be compensated by translational phase with the rule of minimum entropy , but for the most those cannot accord with the approximation of rigid , being the doppler - frequency of the aim is linear changed , by the relax method with short data , increases the resolving performance of multiple target to the aim in the frequency domain , since cross - range resolution is based on the accumulative time , so it is greatly improve the resolution to formation targets by the instant cross - range image which produced by radon - wigner transformation
低分辨isan成像及干涉技术应用研究一因此直接无法分辨编队目标的架数，我们借鉴isar的技术，通过较长时间的相干积累，在多普勒频域上对目标进行分辨。而对于编队目标，可分为近似刚性的多目标和非刚性的多目标，所以对于可以近似为刚体的编队目标相对位置固定，运动方式一致，可以近似看作一个大目标，采用最小墒准则对平动相位的进行补偿，但是大多数并不满足刚体近似的编队目标，由于目标在相干积累时间的多普勒频率近似呈线性变化，通过对较短数据利用relax的时频分析方法，提高了频率域上目标分辨的性能。由于横向分辨率取块于横向积累时间，所以利用radnwigner变换得到瞬时的一维横向距离像大大提高了对编队目标的分辨，对仿真和实测数据的大量分析结果表明此方法的有效性和可行。
