By using the C60 molecular Ih symmetry and vector operation approaches and introducting an adjustable parameter λ,we calculated the atomic coordinates in molecule with C60 construction,which is an icosahedron cutted out twelve vertices.

　运用C60分子的Ih对称性及矢量运算方法,引入调节参数λ计算了正二十面体被截取顶角后的具有C60分子结构的原子坐标。

By introducing the conception of electron coordinate in the m_s m_l coordinates for the same group of electrons, the method to determinate atomic ground state with the electron coordinate was showed.

通过对同科电子引入m(?)、mt、系中电子坐标的概念,给出了用坐标法确定原子基态的方法。

It is pointed out in this paper that the p-q、ip-iq and d-q techniques used in active power filter (APF) design are the methods based on rotor coordinate and the fan-in vector theory is the method based on stator coordinate.

指出有源电力滤波器的设计中所采用的p-q法、ip-iq法与d-q法,都是基于转子坐标系的方法;而扇合矢量法是基于定子坐标系的方法。
