通常我们在实验结束后，要查表将其测得值与表中值加以比较，并以此为根据来判断实验结果的正确与否或进行误差分析。但表中的值也是实验测得的，既然是实验测得的值就与测量时特定的条件与因素有关，在实验结果与之比较时，要根据自己的实验的具体情况和条件，加以具体分析， Usually after the end of the experiment, we must check the table to compare the measured values ​​with the values ​​in the table, and use this as a basis to judge the correctness of the experimental results or perform error analysis. However, the values ​​in the table are also measured experimentally. Since the values ​​measured in the experiment are related to the specific conditions and factors in the measurement, when the experimental results are compared with it, the specific conditions and conditions of the experiment should be used to add specific values. analysis,
