斜率波动图在化工质量管理中的运用

An Application of Slope Surge Diagram in Quality Management

逐批生产的产品单耗、计件合格率等涉及按批产量加权平均问题。以累计消耗ｔ对累计产量ｔ作图，以斜率反映每批单耗，控制界限斜线，兼顾了技术经济统计和逐批控制消耗的需要，简便实用。

The expense of per batch products can been evaluated by means of the slope the diagram of accumulative total yieldvs accumulative total expense in order to solve the problem of weighted average on batch yield. The method can give consideration to both the technical and economic targets and control of per batch expense.
