The reason that HA granules bring positive charge in absolute alcohol may be related tosurface absorption or association reaction with 〓; EPD includes two process, that iselectrophoresis and deposition, wanting to make EPD go with a swing, a critical voltagevalue Vc between two electrodes must be reached. The edge effect affecting EPD can beweakened through introducing pulse direct-current main.

HA颗粒在无水乙醇中带正电的原因可能与其表面吸附或缔合〓有关；EPD包括电泳和沉积两个过程，要使EPD能顺利进行，两极间电压必须达到一临界值Vc；采用脉冲直流电源可削弱边缘效应对沉积的影响。
