The modern, angular building was a sign of Beijing's recent transformation and modernization. 这栋现代,棱角分明的建筑是北京近年改革和现代化的标志之一。
Generation of twisted stigmatic beam and transfer of orbital angular momentum during the beam transformation 扭转对称光束的产生及其变换过程中的轨道角动量传递
The discrete wavelet transformation can analyse the signal in the angular and frequency-domains, thus the useful information in the error signal can be obtained from the multi-level discrete wavelet transformation decomposition. 同时在角度域与频域对误差信号进行分析,对误差信号进行离散小波分解,提取误差信号突变。
Express in self representation about the orbit angular momentum Operator, eigenvector of p electron in hydrogen atom and transformation each other about mechanics quantity representation have been discussed with the theory of representation. We have got succinct practical express form. 运用表象理论讨论了氢原子中的p电子轨道角动量算符及其本征矢分别在^Lx,^Ly,L^z表象的表示及力学量表象的相互转化,得到了简洁实用的表达形式。
This paper mainly introduces the polar coordinate presentation and the orbital angular momentum presentation in Hilbert space and the mathematical transformation between them. 本文主要介绍希尔伯特空间的另两组基矢:极坐标表象和轨道角动量表象以及该二表象间的变换。
Based on the theorems of momentum and angular momentum, a new method for determining the orbit in central force field of inverse& square law is given by the transformation of unit vectors in two coordinate systems. 根据动量定理和角动量定理,通过直角坐标系和平面极坐标系单位矢量的变换,给出了推导平方反比有心力场中轨道的一种新方法。
There is no the global angular rotation but only the space displacements of the nodes ( induding the cantilever plate) in this space displacement field. Thus, greatly simplify the calculation of the geometric nonlinear analysis by not necessarily adopting the coordinate transformation using Euler angle. 这种位移场没有梁段整体转角位移,只有单元端部各节点(包括悬臂板端点)的空间位移,因而作几何非线性分析时,不须采用欧拉角进行坐标变换,大大简化了计算。
According to the method of angular power spectrum for average sound field in shallow water, the transformation relation between arbitrary angle dependence of bottom scattering and the range dependence of long-range reverberation in shallow water homogeneous layer is established. 利用浅海平均声场角度谱分析法,在海底散射的任意角度关系和浅海均匀层远程混响的距离关系之间建立了变换关系。
The transfer method of angular distribution function of one dimension in re-ference [ 1] is applied to the transformation of two dimensions. 将文献[1]中的一维角分布函数的转换方法应用到了二维角分布函数的转换中。
