本文总结了无质量标量场球对称坍缩的数值研究结果。我考虑解族S[p]，它具有这样的性质：一个临界参数值p*将包含黑洞的解与不包含黑洞的解分开。我提出的证据支持以下猜想：(1)p - >p *极限中的强场演化是普遍的，并在任意小的时空尺度上产生结构；(2)形成的黑洞质量满足幂律M（BH）与\p -p *\gamma成比例，其中gamma几乎等于0.37是一个普遍指数。
I summarize results from a numerical study of spherically symmetric collapse of a massless scalar field. I consider families of solutions, S[p], with the property that a critical parameter value, p*, separates solutions containing black holes from those which do not. I present evidence in support of conjectures that (1) the strong-field evolution in the p --> p* limit is universal and generates structure on arbitrarily small spatiotemporal scales and (2) the masses of black holes which form satisfy a power law M(BH) is-proportional-to \p - p*\gamma, where gamma almost-equal-to 0.37 is a universal exponent.
