摘　　要：相比不放回抽样,放回抽样的实施比较简单,操作性强,但缺点在于单元可能被重复抽到,抽出的有效样本量小于等于样本量,不是固定的。本文应用逆抽样的原理,设计了一种放回抽样方法,满足有效样本量固定,并且估计量的性质优良。Conducting sampling with replacement is more simple, but its disadvantage is the units may be sampled repeatedly and the available sample size is random. The paper proposes a new method of sampling with replacement applied by the principle of inverse sampling, which makes the sample size is constant and the estimator is fine.

关 键 词：有效样本量 放回抽样 逆抽样
