阴性控制和阳性控制 阴性对照(negative control)和阳性对照(positive control)是针对“预期结果”而说的。凡是肯定出现预期结果的组,为阳性对照组。凡是肯定不会出现预期结果的组,为阴性对照组。positive-negative control 正负控制 positive-negative switch 正负象转换开关 positive-negative three level a...
阴性对照(negative control)和阳性对照(positive control)是针对“预期结果”而说的。
例句:1.Results: The spots were clear, negative control without interference by TLC.结果:薄层色谱斑点清晰,阴性对照无干扰。2.Results: Characteristic spot can be observed clearly, while the negativecontrol did not show spot.结果:斑点显色清晰,阴性对照无干扰。positive control:阳性对照;...
