如果要监视的数据库系统是用于决策支持(DSS)的，查询比较长而且比较复杂，那么不要让质量控制(QC)代理运行大型的查询。

The study is of opinion that the uncertainty contribution of RON measurement system is, by using this technique, consisted of quality control (QC) sample and in-statistical RON results.

研究表明，采用该技术来评估RON检测系统的不确定度，其贡献量分别是由质量控制（QC）样品和受控RON测试结果两部分合成。

The study suggests that the uncertainty contribution of ICP-AES measurement system is, by using this technique, a combination of quality control (QC) and linear fit.

研究认为，采用该技术来进行ICP AES测量系统的不确定度评估，其贡献量分别是由控制样品(QC)和线性拟合两部分合成。
