ALGEBRAIC PROPERTIES OF THE SEMI-PLANE-SYMMETRIC STATIC SPACE-TIME YIELDED BY SEMI-PLANE-SYMMETRIC NON-NULL ELECTROMAGNETIC FIELDS
半平面对称非类光电磁场产生的半平面对称静态时空的代数性质

The spin coefficients and the tetrad components of the Weyl tensor of the semi-plane-sym-metric static space-time yielded by semi-plane-symmetric non-null electromagnetic fields are found, It is shown that this space-time is of Petrov type I. The behavious of null-vectors and optic scaiars are also discussed.
