用矩阵的方法表示协变、逆变极坐标系及相互转化关系和协变、逆变极坐标系与笛卡尔坐标系的转换关系，称为极坐标系的矩阵方法。利用该方法给出了质点运动学和质点动力学上常用物理量在极坐标系下的具体形式及其与在笛卡尔坐标系下具体形式的转换，并给出相应算例。
用矩陣的方法錶示協變、逆變極坐標繫及相互轉化關繫和協變、逆變極坐標繫與笛卡爾坐標繫的轉換關繫，稱為極坐標繫的矩陣方法。利用該方法給齣瞭質點運動學和質點動力學上常用物理量在極坐標繫下的具體形式及其與在笛卡爾坐標繫下具體形式的轉換，併給齣相應算例。

To show the conversion relationship between covariant polar coordinates and inverse polar coordinates as well as the conversion relationship between the two systems and descartes coordinates by using matrix is called polar coordinates matrix method.By using this method,obtained the specific forms in polar coordinates of frequently-used physical quantity of the particle kinematics and particle dynamics along with the conversion relationship of its specific forms in descartes coordinates,and gave the corresponding numerical example.
