凝胶的SEM照片可见，海藻酸钙的冷冻干燥颗粒内为较大的圆孔，海藻酸锌凝胶内为较小的长孔，表明海藻酸锌高分子链在凝胶颗粒中的体积分率相对较大同时刚性较强；卵清蛋白从海藻酸凝胶颗粒中释放的试验结果表明，由于上述海藻酸锌凝胶的特性，导致海藻酸锌对卵清蛋白扩散阻滞作用相对较强；根据试验数据计算得卵清蛋白在海藻酸钙、海藻酸锌凝胶颗粒中的扩散系数分别为1.19×10-7、0.07×10-7cm2/s，利用阻滞模型计算得海藻酸锌高分子链在凝胶颗粒中体积分率约为海藻酸钙高分子链在凝胶颗粒中体积分率的1.7倍。

When the concentration of zinc nitrite is lower than 0.1 M,(002) is the prior face for zinc oxide. As the concentration raise, the other kinds of crystal face would appear. Among those data,(002) grows the best when the concentration of zinc nitrite is 0.06 M. We add lactic acid and citric acid respectively; there is an carboxyl group on the lactic acid and three carboxyl groups on the citric acid. The monodentate of lactic acid helps the growth of zinc oxide, compared to the tridentate of citric acid which can only produce zinc oxide film under very low concentration, but the growth of (002) face is not that stable as adding the lactic acid and zinc will electrodeposit to substrate.

实验中，当硝酸锌浓度低於0.1 M 时，氧化锌以(002)面为优选位相，当浓度提高，其他晶面将会出现，当硝酸锌为0.06 M，(002)晶面成长最佳，分别加入乳酸和柠檬酸，乳酸结构上有一羧基团而柠檬酸有三个羧基团，单芽基的乳酸有助於氧化锌成长，对照於三芽基的柠檬酸，则必须在极低的浓度下才能制备氧化锌薄膜，但(002)面成长却没有添加乳酸来的稳定而金属锌也会电沉积到基板上。

Adopting cathode protection of the zinc materials as an effective protection method, which already applied more and more in many field. For example, Hot-dip galvanisation, galvanization, electric arc spray zinc 、sherardizing, etc. But that method are with lots of shortcomings. For example, hard to apply

采用锌材料阴极防护的方式，作为一种有效的钢铁防护手段，已经得到越来越多的应用，诸如热浸镀锌、电镀锌、电弧喷锌、热喷锌等工艺手段，但鉴于这些工艺存在施工难度大、环境污染重、能耗高、锌层受损难修复等弊端，使得发展受限。
