分析了D0-D4黑洞解在四维超引力中的吸引子机制。我们的分析基于新的精确解，它清楚地显示了极值非BPS黑洞的吸引子机制。我们的解将模作为一般复数场来考虑，而在前人得到的几乎所有非BPS解中，模数场被限制为纯虚场。
We analyze the attractor mechanism for the D0-D4 black hole solution in the four-dimensional supergravity. Our analyses are based on new exact solutions, which show explicitly the attractor mechanism for the extremal non-BPS black holes. Our solutions take into account the moduli as general complex fields, while in almost all the non-BPS solutions obtained by previous authors, the moduli fields are restricted to be purely imaginary.
