mathematical operation造句

• Correlation based on fourier transform ( ft ) is one of the most important mathematical operations that can be optically implemented because it can be used for pattern recognition and image feature extraction , and so on
  基于傅里叶变换的相关是在光学上能够实现的一种重要运算，它已用于模式识别和图像特征提取等。但传统的相关操作具有平移不变特性，因而具有局限性。
• Proving lagrange theorem mean through the introduction of auxiliary function , this article puts forword the methods of building auxiliary function by the mathematical operations and two functions compound operation ; this is a method building all elementary function by the basic elementary function , which is a way to solve the problem of the auxiliary function building
  摘要文章给出了用四则运算以及两个函数的复合运算构造辅助函数来证明拉格朗日中值定理的方法，这也是用基本初等函数构造全部初等函数的方法，因而比较圆满地解决了辅助函数构造问题。
• Case 1 : when there is no relative measurement , each satellite uses its own on - board attitude sensors to determine its attitude , and exchange the information through the communication link between formation satellites , and then the relative attitude is determined through simple mathematical operation . case 2 : based on the range measurements of gps like sensors , using two - point measurement of the relative orbit state to establish relative orbit and attitude kinematics and measuring equations . and state estimation is achieved through the extended kalman filter technology and unscented kalman filter technology , respectively
  方案一,在星间无相对测量时,由卫星自身携带的姿态敏感器实现单星高精度姿态确定,利用星间通信链路进行信息交互,通过简单的数学计算获得星间相对姿态;方案二,利用类gps相对测量,建立了编队卫星相对轨道运动和相对姿态运动模型及相对距离测量方程,推导了两点相对轨道运动模型,设计了扩展卡尔曼滤波器及uscented卡尔曼滤波器,对相对位置、速度和姿态进行估计。
