摘要
介绍了对循环水质量控制的必要性和直方图法、过程能力计算等数理统计方法。绘制了直方图,并计算过程能力指数,对循环水质量控制水平作出评价。通过实际应用控制图,有效地提高循环水质量控制能力。
The necessity of the circulating water quality control and means of mathematical statistics such as histogram and process competence were introduced in this paper. The evaluation on the control level of circulating water via drawing histogram was made and process competence index was calculated. Finally, how to improve the competence of circulating water control quality effectively by making use of control chart in practicing was discussed.
