ADPODS posses stable Surface chemical properties when dissolved in 10% sulfuric acid, 10% sodium hydroxide or 10% sodium chloride aqueous solutions. ADPODS s emulsifiability and detergency at 650mg/L water hardness are very good.4 The micellar aggregation number of C16-MADS was determined by molecule fluorescence probe method.

采用分子荧光探针法测定了C_(12)-MADS与C_(16)-MADS的胶团聚集数，在一定的表面活性剂溶液浓度1.25×10~(-2～1.10×10~(-1)mol·L~(-1)范围内，N_m随浓度的增大而线性增大；体系温度和NaCl浓度对N_m的影响极小；胶团内核的微极性明显大于传统阴离子表面活性剂。

As a result of chemical contains what hard water softeners, so that water to soften the water, flacherie self-aggregation intracelluar intenerated because the loss of water, when huaguang PD developering is water dilution of 1: 4, press ideal calculation, the working fluid anionic surfactant concentration, in its critical micelle concentration.

由于显影洋含有硬火不硬化剂何使火不硬化，火虽不纬不硬化，可火洋的离子含度并未因火的不硬化而减众，当华平PD显影液被火按1：4浓缩后，按理想状况筹算，处事液洋阴离子暗不天活性剂的浓度，在它的临界胶束浓度边。
