化学中讲的携带效应(Carry-over effect
What are carry-over effects?A carryover effect is an effect that "carries over" from one experimental condition to another.Whenever subjects perform in more than one condition (as they do in within-subject designs) there is a possibility of carryover effects.For example,consider an experiment on the effect of rate of presentation on memory.Subjects are presented with a list of words and asked to recall as many words as they can.In one condition,the words are presented one word per second; in the other condition,the words are presented two words per second.The question is whether or not having performed in one condition affects performance in the second condition.Perhaps learning the first list of words will interfere with learning the second list because it will be hard to remember which words were in each list.Or maybe the practice involved learning one list will make it easier to learn a second list.In either case,there would be a carryover effect:performance on the second list would be affected by the experience of being given the first list.Assume two experimental conditions:A1 and A2.
Half the subjects perform in Condition A1 first and then in A2; the other subjects perform in Condition A2 first and then in A1.The following table of means shows "symmetric carryover effects."
我见过的是因为液体蒸发等原因,将一些液态小滴弹到气体中
比如家中烧鱼时常加些料酒,就利用了携带效应,带腥味的胺类物质溶于酒精,酒精易挥发,便将这些一起带出去了,从而去除了腥味。 这是我看的文献中携带效应的图,表现的是先引入5分钟甲醇,再引入20分钟1%硝酸后,时间变化对测定的影响。我想问携带效应和记忆效应有什么区别吗?

共轭效应和共振效应有什么区别?共振效应指的是化学中的共振论,一种电子效应,有机中讲到的,不是物理中的共振现象…… 我主要是想知道两个概念确切的区别,大二的课本讲得很模糊
液体是不是也有焦耳汤姆逊效应和节流膨胀效应焦耳汤姆逊效应和节流膨胀效应的定义中都是讲的气体,液体是不是也有这种效应呢?
carry on和carry over区别
细胞中携带遗传信息的物质是,

化学中所讲的金属以游离态存在是什么意思?
化学实验过程中会被携带的气体一定要有挥发性吗?如果是的,那么水为什么会被携带,如果不是那为什么在实验中产生挥发性气体时要进行适当的措施?
詹森效应怎么讲?
1.红细胞可携带氧气,可进行有氧呼吸2.在效应B细胞中,内质网和高尔基体特别发达这两句话那句是对的,请说明理由
