Through compared with the difference of the sampling inspection's OC curves between existent and nonexistent inspection error by utilizing grouping method, we get the conclusion that all the traditional methods are designed on the premise that there is none inspection error exist, so it would terribly depress the probability of acceptance and couldn't veritably reflect the quality of the lot for inspection, if the inspection error is exist when sampling inspecting.

同时通过对集团检验错误存在与否的抽样检验特征曲线的比较，指出：以往的集团抽样检验方案设计，都是在假设无检验误差前提下设计的，在抽样检验中，若存在检验错误，会严重影响抽样检验的接收概率，使抽样检验结果不能客观地反映检验批的质量。

And the temperature error could be divided into accidental error and systematic error.

其温度误差分为随机误差和系统误差两部分。

Sampling error or allowable error is conventionally accepted between 1% and 10%; however, it is suggested that sampling error should be carefully assessed in light of the nature of the derivation of the population proportion and other aspects of the initial data.

抽样误差或允许误差是接受常规的1 ％和10 ％，但是，有人建议，抽样误差应当认真评估根据的性质推导的人口比例和其他方面的初步数据。
