本论文首次采用脉冲电流技术在无模板、非限域的条件下合成了具有纳米纤维结构的导电聚苯胺，并就其在电化学生物传感、电化学催化、电化学电容等领域的应用展开了研究，论文主要研究结果如下： 1。

Thus the pulse parameters were determined based on examination of the microstructure, grain size, hardness and tensile strength of the deposits obtained at different average current densities with constant pulse-on time (ton =2 ms) and pulse-off time (toff= 45 ms).

结果表明，在恒定脉冲模式下(脉冲导通时间2ms，脉冲断开时间45ms)，镀层晶粒尺寸随电流密度的上升而明显下降，硬度与强度则显著上升，当电流密度超过8A/dm2时，抗拉强度开始急剧下降而硬度保持6kN/mm2的高位基本不变，当超过12A/dm2时，硬度也开始下降。

The result indicate that: the electrodeposition of zinc on nickel and tungsten substrates involves instantaneous three-dimensional nucleation. The coating is the best when the current density is 4mA/cm2 and the temperature is 80 ℃. The coating by the method of the impulse electrodeposition is better than the direct current electrodeposition. Especially when f is 100Hz, ton/toff is 2/8 and J is 8mA/cm2, the coating is clean and uniformity. The crystal size is nearly 0.3μ m .

结果表明：阴极反应为准可逆反应，锌离子在镍电极和钨电极上形核是三维瞬时形核半球形扩散长大过程，直流电流密度为4mA/cm2，温度为80 ℃时，镀层质量最好；脉冲电沉积得到的镀层要优于直流电沉积得到的镀层，尤其在脉冲宽度为2ms，脉冲间隔为8ms，电流密度为8mA/cm2时，得到的镀层光滑而均匀，颗粒大小接近0.3μm。

The role of a-Si:H sublayers is to interrupt the continuous growth and limit the thickness of pc-Si:H sublayers. The a-Si:H sublayers are deposited by two methods, one is fabricated by low hydrogen dilution ratio R = 4, and the second is deposited by pulse-wave modulation plasma with turn-on time (TON = 25 ms) and plasma turn-off time (TOFF = 75 ms).

阻断层所用的非晶矽薄膜采用两种方式制作，第一种是利用低氢稀释比(R = 4)制作的非晶矽，第二种是利用脉波调变电浆开启时间及开关时间分别为25ms及75ms pulse(25ms/75ms所制作的非晶矽。
