利用N体模拟研究了宇宙中高密度峰的分布。与随机高斯场的分析结果相比，背景密度场的非线性演化显著地改变了峰值的统计性质。特别是，在有偏星系形成理论的背景下，讨论了初始密度峰的丰度和关联。参考文献31篇。
Distribution of the high-density peaks in the universe is examined using N-body simulations. Nonlinear evolution of the underlying density field significantly changes the statistical properties of the peaks, compared with the analytic results valid for the random Gaussian field. In particular, the abundances and correlations of the initial density peaks are discussed in the context of biased galaxy formation theory. 31 refs.
