The control chart based on the geometric distribution(g-type chart) has shown to be competitive with p or np chart for monitoring the proportion especially for application in high quality manufacturing environments. However when the cases with LCL=0 occur, plotting values beneath the LCL is impossible given the non-negative nature of units, such type of lower control limits no ability to detect rate increase.

但是由于几何控制图的自然下限的问题，在其使用过程中若控制下限LCL＜0，则取其自然下限为0，这使得几何控制图在此情况下对于检测不合格品率p的增加是几乎不起任何作用，而此问题也是实际中我们最需要检测并作判断的问题。

The interfacial chemistry, synergistic effects and interfacial kinetics of thesynergistic extraction system D_2EHPA-MPA-Fe~(3+) have been studied, where MPA is amono-alkyl phosphate extraction with long carbon chain. D_2EHPA in the mixed extractionsystem strongly exhibits the effect on the thermodynamics of micella formation and interfaceproperties of MPA. Some thermodynamic parameters of micella formation were obtained.The interfacial adsorption behaviour of D_2EHPA is opposite to that of MPA. Theemulsification for single MPA and the mixed system was discussed. The synergistic effectswere found in this mixed extraction system. It is proved that the process of Fe~(3+) extractionfor non-mixed extraction system is controlled by chemical reaction, the controlling reactionoccurs at the interface, and the reaction rate equation is obtained.
