| 1. | The spatial position of sound source is one of attributes in human ' s auditory perception 声源的空间位置是人们在真实环境中对声音感知的重要属性。 |
| 2. | Establish the platform of the interlligent transportation system based on geographic information and spatial positioning system 构建智能交通地理信息及定位平台 |
| 3. | Trajectory is the focus of spatial relation , and the spatial expression , which is used to describe the spatial position of the trajectory , consists of localizer and landmark 其中,射体是空间关系的主体,而空间表达式描述了射体的空间方位,主要由方位词和界标组成。 |
| 4. | In the gravitational field , ideal gas molecules are affected simultaneously by two opposite effects in terms of momentum ( or speed ) distribution and spatial position distribution 摘要理想气体分子在重力场中按动量(或速度)的分布和按空间位置的分布同时受到两种对立作用的影响。 |
| 5. | Gis deals with two types of data : spatial data and attribute data . the former mainly refers to data that is closely related to spatial position and spatial relation ; and the latter refers to non - spatial data among geographical elements Gis处理的数据分为两类:一类主要是与空间位置、空间关系有关的数据,称为空间数据;另一类是地理元素中非空间的数据,称为属性数据。 |
| 6. | With the development of our society , the situation we confront everyday is becoming more and more complicated , and most decision problems have something with spatial position . therefore the spatial decision support theory and technology research is very important 随着人类社会的发展,我们面临的决策问题越来越复杂,且大部分的决策问题都与空间位置有关,因此空间决策支持理论与技术的研究至关重要。 |
| 7. | In this paper , the strategy of combining the information of gray level and spatial position is adopted to achieve non - texture image segmentation , and two novel approaches are presented . the first approach is a generalization of otsu algorithm 本文使用将灰度信息和空间位置信息相结合的策略来实现非纹理图像分割,提出了一种结合空间信息的阈值化算法,和一种针对sar图像的与区域生长相结合的模糊域分割算法。 |
| 8. | Based on two drill holes with known geological conditions and adopting relative phase wave , the authors obtained two diametrically different types of ip relative phase sounding curves for orebodies and carbonaceous beds respectively , which can be used to distinguish anomalies of different properties and determine spatial positions 摘要根据矿山提供的两个已知地质条件的钻孔,采用激电组合波相对相位测深法获得了在矿体上和炭质层上两种完全不同类型的激电相对相位测深曲线,不仅可以区分异常性质,而且可以空间定位。 |
| 9. | This allows us to use much less elements to model complicated structures such as the stiffened beam and tower in suspension bridge , while it can still reflect various details such as the mechanical character , geometry , spatial position , the contribution to the system stiffness and mass , of each member involved . by adopting the assembled element , we can use usual pcs to perform the nonlinear analysis of long - span suspension bridges 组合单元突破了传统有限元对于不同材料或不同构件必须采用相应不同单元的限制,对悬索桥的索塔、加劲梁等复杂结构,能用较少的单元进行模拟,并且仍然能够仔细反映其内部各个构件的力学特征、几何尺寸、所在空间位置以及其对系统刚度、质量的贡献,实现了用普通微机进行大跨度悬索桥空间非线性分析。 |
| 10. | Lacking of space locality in time domain , fourier analysis can only make certain of the integral singularity of a function or signal . as a result ; it is difficult to detect the spatial position and distribution of broken signal by fourier analysis . wavelet analysis has the characteristic of spatial locality , and its wideness in both windows of the time and the frequency can be adjusted , so it can analyze the details of a signal 小波分析优于傅里叶之处在于,小波分析在时域和频域同时具有良好的局部化性质,因为小波函数是紧支集,而三角正、余弦的区间是无穷区间,所以小波变换可以对高频成分采用逐渐精细的时域或空间域取代步长,从而可以聚焦到对象的任意细节。 |
