单因子变量原则是指实验中只确定一个自变量,控制其他实验因素不变,观察其对实验结果的影响。这样既便于对实验结果进行科学的分析,又能增强实验结果的可信度和说服力。在解决与实验结果有关的高考试题时,灵活运用单因子变量原则,找准自变量,可使复杂的问题简单化,快
The principle of one-way variable means that only one independent variable is determined in the experiment, the other experimental factors are not changed, and the influence on the experimental results is observed. This will not only facilitate the scientific analysis of experimental results, but also enhance the credibility and persuasion of experimental results. In solving the test results related to the college entrance examination questions, the flexible use of the principle of single-factor variables, identify independent variables, complex problems can be simplified, fast
