The influences of the inclusion of Na~+ into each conformer (C7AB, C7"AB, C7eqB, C5A, C7axB orα"B) of AD molecule on the Ramachandran angles of molecular backbone and the hydrogen bonds in AD moiety were discussed in detail. It was found that in the forming process of bidentate structures of Na~+-AD ion-complexes, the original H-bonds in AD molecule were fully broken down, accompanying with the new formation of the two Na-O bonds.

Molecularly imprinted polymers of sulfamethazine(SM 2 ) were prepared with silica gel as a sacrificial material, methacrylic acid and 4 vinylpyridine(4 Vp) as functional monomers, glycol dimethacrylate as crosslinker. The polymer properties were investigated by static adsorption experiments. Scatchard analysis shows that the adsorption ability of MAA MIP is superior to that of 4 Vp MIP. The dissociation constant of MAA MIP is 9 59×10 -4 mol/L. The value of apparent binding a...

B。电穿孔技术：直接作用于皮肤，瞬间增强皮肤组织的可渗透性。在电击的作用下，细胞的脂质二重层上形成电击孔。在电击孔形成的同时，使得原先无法被细胞吸收的亲水性分子能够穿透并进入细胞内部。电击孔一旦形成，则根据电击的长度，在数秒种至数分钟之内保持打开状态。C。电渗透技术：电渗主要作用于将要分散的物质分子，帮助其顺利穿透并进入肌肤内部，性质相同的电荷相互排斥，因此对正极的营养分子施加正电流，可将营养分子推入皮肤组织。此时，中性分子也一道穿透并进入肌肤内部。
