order of matrix meaning in Chinese
阵阶
Examples
- Similarly , the order of matrix multiplication is important
同样，矩阵相乘的顺序也是重要的。 - The aim of this paper is to study the generalized inverse of matrices on rings , the generalized inverse of morphism and partial ordering of matrices
本文研究了环上矩阵的广义逆，范畴中态射的广义逆，并研究矩阵的偏序。 - The partial ordering of the matrices is facous on the matrix theory , many mathematicians have been engaged in studying the partial ordering of matrix such as kinds of partial ordering and its application
矩阵的偏序是当前矩阵论研究的一个热点，国内外许多学者从事矩阵偏序的研究，他们研究各种类型的矩阵偏序，并应用到数理统计等学科中。 - On such a basisthe commonly used monomial error accumulating totals correction method is introduced . the author proposes a coordinate transformation method to deal with its drawbacks of maths model imperfection , not applicable to lange - angle deviation and adding to the difficulties of equipment . while orientating the order of matrices according to the principle of the accordance between coordinate ' s rotating order and the physical process of device measuring , a strict maths model of the influence of axis system deviation on surveying angles is concluded and the corresponding correction method is induced . its far - reaching meanings are as follow : ( 1 ) the maths model of the influence of axis system deviation on surveying angles established by the new method is concluded after considerations for the three deviations simultaneously . changes under all circumstances are included , so it is theoretically a perfection of maths method
在此基础上介绍了国内目前采用的轴系偏差对测量角影响的经典改正方法?单项差累计改正法，并针对该方法存在的数学模型不完善、对大角度偏差不适用、增加设备调整难度等缺陷，提出采用坐标变换方法，并根据坐标的旋转次序与设备测量的物理过程相符合的原理定位各矩阵的先后顺序，推导出了轴系偏差对测量角影响的严格数学模型，归纳建立了相应测量角的改正方法。 - In term of the prediction problem , the fourth chapter discusses its superiority of the optimal and classical predictors based on the ridge estimation , and gives an necessary and sufficient condition of comparison of its superiority under the condition of criterion by some properties of partial ordering of matrix
借助矩阵中l ? wner偏序的一些性质，获得在此判别准则下判别两类预测量最优性的充要条件。为研究基于有偏估计关于两类预测量的最优性判别问题提供了一种方法和思路。
