摘　　要：随机化抽样方法对敏感性问题进行调查,已经成为社会敏感性问题调查的常用手段。在一定条件下,改进后模型的精度比Warner模型的高,说明距离平衡抽样排除临近单元设计方法比SRSWR抽样设计方法更能真实地反映实际情况。Using randomized sampling to research the sensitive questions has become commonly used methods in society.Under certain conditions,the improved new model of efficiency higher than Warner model of efficiency.Distance balanced sampling plans excluding contiguous units could more reflected the actual situation than SRSWR sampling design method.

关 键 词：距离平衡抽样排除临近单元 WARNER模型 Horvitz-Thompson估计量
