The control group and experimental group are compared against each other in an experiment. The only difference between the two groups is that the independent variable is changed in the experimental group. The independent variable is "controlled", or held constant, in the control group. A single ...
control group 对照组experimental group 实验组我想实验组是在正常情况条件下进行科学实验的，而对照组则是在条件不同的情况下，同样的实验，看有什么差别，科学家来进行对比。
实验组(experimental group)与控制组(control group)(东北财大2010年研;华中农大2010年研) 相关知识点: 试题来源: 解析 正确答案:实验组是指实验过程中接受实验刺激的那一组对象。即便是在最简单的实验设计中,也至少会有一个实验组。控制组又称对照组,它是各方面与实验组都相同,但在实验过程中并不给予其实验...

The first group was a container without the AMTC, and the second was a container that had the AMTC replaced with a low thermal conductivity material (LTCM). Both these scenarios are common practice in commercially available thermal insulating containers. We examined the temperature variations of ...
DMTr-protected ASOs were treated with 28% aqueous NH3 at 55 °C for 12–14 h to cleave oligomers from the CPG, and all the protecting groups except the terminal DMTr group were removed. For the deprotection of the 5′-DMTr group, ASOs were treated with 4% (v/v) aqueous ...
With respect to the management and control of energy networks, the participation of Terna, Enel Group, Snam and eVISO in this event was particularly relevant. In order to work effectively and efficiently, the overall power system must be able to ensure the balance between power production and ...
b Group activity during behavioral trials. c Upper: windows of significantly increased activity during the delay and around cue and response. Bootstrap parameters: 5000 iterations, α = 0.001. Lower: windows with a significant difference in activity between indicated projection populations. Bars ...
