摘　　要：等概率原则是多阶段随机抽样过程中必须体现的原则。通过对分立式多阶段随机抽样方式的分析 ,发现在其随机抽样过程中存在着违背等概率原则的问题。据此 。Equal probability principle is the principle that must be followed in the process of multi stage random sampling.Through analyzing multi stage random sampling in separate groups, we discover that in the process, there exists the question of violating the principle of equal probability.For this reason, the paper suggests a comprehensive multi stage random sampling process.
