2) sampling effect
抽样效应
1.
With eight species of unicellular algae cultured in random combinations to construct the assemblages with different degrees of richness,the increase pattern of colony biomass with the change of species richness was investigated,and the sampling effect was detected by using multiple variance analysis(MANOVA) method.
通过8种甲藻构建不同物种丰富度梯度的集群进行室内一次性培养实验,探讨了集群生物量随物种丰富度的增长模式,运用多因素方差分析检验集群内是否存在抽样效应。
2.
The interpretation of these experiments, however, has been controver-sial because two types of mechanisms," niche complementarity" and" sampling effect", may operate.
然而对这些实验结果的解释却产生了激烈的争论，因为有两种机制——“生态位互补”和“抽样效应”都可能会产生这种结果。
3) sampling efficiency
抽样效率

After discussing the limitation of these existing methods,a viewpoint that the stub-network instead of the IP address should be taken as the sampling granularity was put forward,and a self-contained destination selection method that was termed all stub-networks coverage and two-step random selection w.
为提高Internet路由器级拓扑测量的完全性,给出了完备目标集合的定义,介绍了已有测量目标选择方法并分析其不足之处,提出了“以桩网络而不是IP地址为抽样粒度”的观点和“桩网络完全覆盖,两阶段随机选择”的完备测量目标选择方法。
