研究了球对称带电黑洞在自引力无质量标量场的非线性扰动下的柯西视界（CH）奇异性。我们推导出蓝移因子的发散率的精确表达式，即标量场\ensuremath{\Phi}和面积坐标$r.$的出射方向的导数。这两个衍生物被发现沿着收缩CH的增长完全一样1/r。我们的结果是有效的沿着CH奇点，到全聚焦点。这些精确的解析表达式进行了数值验证。
We study analytically the features of the Cauchy horizon (CH) singularity inside a spherically symmetric charged black hole, nonlinearly perturbed by a self-gravitating massless scalar field. We derive exact expressions for the divergence rate of the blue-shift factors, namely the derivatives in the outgoing direction of the scalar field \ensuremath{\Phi} and the area coordinate $r.$ Both derivatives are found to grow along the contracting CH exactly like $1/r.$ Our results are valid everywhere along the CH singularity, down to the point of full focusing. These exact analytic expressions are verified numerically.
