一般带电柱型黑洞引力透镜效应

Strong Gravitational Lensing Effect at the Background of Cylindrical Black Hole Space-time

把引力透镜的背景时空推广到了新的一般带电柱对称黑洞,得到了一般带电柱对称黑洞做引力透镜时的引力场极限参数﹑偏转角﹑像之间的夹角与透镜放大率,找出了这些量之间的关系,并与其他背景时空下的情况作了对比和分析.

This paper extends the space - time background of strong field gravitational lensing effect to a new general charged cylindrical black hole. We not only study the charged cylindrical black hole＇s gravitational lensing and obtain the coefficients such as the strong field deflection limit coefficients, the deflection angle and the magnification, and find the relationship between them, but also do certain contrast and analysis with the conditions under the other background space time.
