- Based on the correct evaluation of the means and covariance of the measurement error in cartesian coordinate system , the algorithm processes the radar measurements sequentially , and the linearization of measurement equation is no longer neccessary
作者推导了有测速数据时的去偏转换卡尔曼滤波算法。此算法估计精度和计算效率比以前的方法有较大改善，对测量方程不做近似处理。 - The method is as follows : calculating the length , angles and coordinates of pre - cast hollow slab in cartesian coordinate system , and then adjusting the width of hollow slab beams and length of cantilever boards to make the linear cantilever slabs close to the transition of mute
具体方法是：采用直角坐标系计算预制空心板斜长、首尾夹角和起终点坐标，根据计算结果与路线线形之差，多次调整空心板梁的梁板宽度和悬臂长度，使外悬臂折线满足路线的缓和曲线线形。 - In the first part of the paper , the explicit form of difference equation and periodic boundary condition is derived in cartesian coordinate system . secondly , the dispersive characteristic is analyzed in cylinder coordinate system for many high power microwave devices use cylinder sws . and then the method is extended to calculate the band structure of 2 - d photonic crystal , a modified yee ’ s grid is introduced to calculate the dispersive characteristic in the case of triangular lattice , so that both square lattice and triangular lattice cases can be solved in cartesian coordinate system
周期电磁结构的一个重要应用就是用作高功率微波器件中的慢波系统,考虑到目前大部分高功率微波器件的慢波系统多采用圆柱周期结构,在论文第四章中,在圆柱坐标系下,给出了差分方程和周期性边界条件的具体形式,同时编写程序,分析了milosws ,盘荷慢波结构的色散特性。
百科释义
A Cartesian coordinate system specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances from the point to two fixed perpendicular directed lines, measured in the same unit of length. Each reference line is called a coordinate axis or just axis of the system, and the point where they meet is its origin, usually at ordered pair (0,0).
