primary sampling

Sampling observation result is, immanent quality is primary eligible, and exterior quality is a problem great.

抽检结果是, 内在质量基本都合格, 而外观质量则是问题多多.

The designed control circuit consists of two components: isolating and sampling circuit used for sampling output voltage and isolating primary and secondary of the converter; type 2 error amplifier, designing compensated circuit for error amplifier to stabilize feedback circuit system.

设计的控制电路由两部分组成：隔离、取样电路，用来采样输出电压并实现变换器初、次级电气隔离；2型误差放大器，设计补偿电路使反馈电路系统稳定。

The study of primary problem of sampling survey to social economic statistics

抽样调查在社会经济统计中应用的基本问题研究

In this way, the'contact point-sampling-contact point'access mode of the wiring terminal of the primary cable is changed to be the'sampling-contact point-contact point'mode.

这样，将一次电缆接线端子接入方式由现有的“接点―采样―接点”方式改进为“采样―接点―接点”方式。

For the relationship of species diversity and primary production, single sampling strategy within growing season would lead to underestimated of complementarity effect because of neglect of temporal niche complementarity in plant communities.

在植物群落中，对于物种多样性和初级生产力之间的关系而言，生长季内单次取样策略因为没有考虑时间生态位的互补，将会导致对生态位互补效应的低估。
