Otherwise, the optimal theoretical sampling number of the larva and the sequential sampling model were obtained.
并确定了该天牛幼虫林间调查的最适理论抽样数和序贯抽样模型。
Under some level of error, the theoretical sampling number should decrease as the average density of the mite increases.
在相同误差水平,理论抽样数随平均虫口密度的增加而减少。
The model data conversion, the population sequential sampling and the theoretical sampling number model were also built up in the paper.
在分布型研究基础上,探讨了资料代换模型,最适抽样数和种群序贯抽样模型。
The results showed that the higher the population density of the larvae, the less is the theoretical number of sampling clumps;
结果表明,幼虫的种群密度愈高,理论抽样数就愈少;
Additionally, the method has a great theoretical meaning for the standardization of the sampling interval and sample number in water qualities experiments.
此外,分段映射反演模型对野外水质样本采集实验的规范化具有较大理论指导意义。
