再分别计算出各层的最优样本轮换率和总体的样本轮换率。
Then the paper computed the best sample rotation rate for each stratum and the whole.
提出了在林业信息资料的抽样调查中、最优样本轮换率的问题。
The question of the best rate of the sample book's rotation in the sampling survey of forestry information material is arisen.
由于该抽样调查采取的是分层抽样，因此相应地用分层抽样下的样本轮换研究。
As the sampling survey is stratified sampling, so the research of the sample rotation is under the stratified sampling.
