中文摘要：

聚乙烯醇（PVA）被引入多孔海藻酸钙（CA）薄膜中,形成多孔CA-PVA复合膜。利用扫描电子显微镜（SEM）对其进行表征。将制得的多孔CA-PVA复合膜与肌红蛋白（Mb）组装在玻碳电极上,形成Mb-CA-PVA复合膜修饰电极。电化学实验结果表明,Mb在该复合膜上表现出较好的电化学活性。

英文摘要：

The porous CA-PVA composite films were successtu/ty prepared by introducing poly alcohol（PVA） into the porous calcium alginate （CA） films. It was characterized by scanning electron microscopy （SEM）. The porous CA-PVA composite films were used to incorporate myoglobin （Mb） on glassy carbon electrode to produce Mb-CA-PVA composite film modified electrode. Electrochemical experiments demonstrated that Mb incorporated in the composite films showed good electrochemical activity.
