| 摘 要： | 利用Ｘ射线衍射仪－电化学装置－两台微机联机组成的Ｘ射线衍射差谱全自动电化学测量系统，并结合特制的电解池，现场测定了普鲁士兰修饰电极薄膜在电化学变过程中的Ｘ射线衍射差谱。结果证实在变色过程为了平衡体系电荷而进入和脱出修饰薄摸的Ｋ＾＋导致了薄膜晶体结构的转变。理论计算的Ｘ射线衍射差谱与实测结果基本一致。

| Abstract: | The crystal structural transformation of Prussian blue modified electrode during the color-changed reaction were studied by using in situ X-ray diffraction electrochemical subtraction technique. To maintain electric neutrality that K+ plunged into and displunged from the modified electrode results in the structural transformation of this film. The X-ray diffraction difference patterns calculated theoretically is consistent with the measured. |
