摘　　要：主要研究了密度函数核估计逼近的速度,用Bootstrap方法对核密度进行估计,在适当的条件下,进一步提高了密度核估计Bootstrap逼近的速度,所得到的结果使得密度核估计Bootstrap逼近的速度与密度函数及其导数之间的关系更加的明确.This paper is manly study Bootstrapping approaching speed of kernel density estimates,The kernel density is estimated by the bootstrapping methods.On certain condition,the speed of Bootstrapping approaching for kernel density estimates has been further improved.The results make the relationship between Bootstrapping rates and density function and its derivatives is more clearly.

关 键 词：密度核估计 BOOTSTRAP法 逼近速度
