The results show that, after treated with microwave radiation, the surface free energy of the powder is enhanced from 39.6mJm^(-2) to 41.8mJm^(-2), This is mainly caused by the rearrangement of electric charges on the grain crystal surface, and this phenomenon is coincident with the theory of electron transition caused by energy band splitting of the grain crystal surface.

测定结果显示微波辐射后硫酸钙粉末的表面自由能得到提高，从39.6mJm^(-2)增加到41.8mJm^(-2)，其主要原因是使硫酸钙表面能的极性成分得到了较大的提高。这一结果归于微波幅射引起晶粒表面的电荷重排，与晶粒表面能带分裂引起的电子跃迁理论是相吻合的。

The main factors governing photoinduced toxicity of the anthraquinone are molecular polarity, the ability of electron transition and the largest negative net atomic charges.

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.
