Firstly, the different effect of rectorite modification for the mechanical property of E-51 system were compared; the effect of organic clay for the viscosity and Gel-time of pure E-51 epoxy resin were checked separately; the influence of organic clay for hardening process was studied with FTIR technology; And, the infection of organic rectorite content in matrix for the mechanical property thermal-wet tolerance property aging resistance property and medium endure property for the both of two system were studied relatively. The effect of organization for the inter-layer distance of clay was denoted by XRD technology; To probe into the thermodynamics status about reaction, we investigated the heat discharging of reaction system in the help of DSC. The impact and crooking of solidifying system was observed with the SEM to investigate the decentralization of organic clay, and, at the base of this ,we discuss the mechanism of clay toughing-buildup polymer matrix.

The results demonstrated that laurocapram disrupts the highly ordered lipid structure of stratum comeum and makes the structurs of SC loose,which causes the outermost cell of SC easy to exfoliate and decreases the barrier function of skin for the transdermal absorption of drug;Meawhile, laurocapram penetrating into the intracellular matrix of SC cells fluidizes the filaggrin matrix protein and swells the dermal SC, which could increase the free volume of drug and water content in the SC.

探讨氧酮促进洛美沙星透皮吸收的作用机理。结果表明，氮酮通过以下途径促进药物透皮吸收：（1）作用于表皮角质层细胞间脂质。使角质层变得疏松。细胞间距增大。外角质层细胞易于脱落。降低了皮肤对药物的屏障作用；（2）氮酮进入角质细胞内。与细胞内基质相作用。引起基底角质层肿胀。
