The circinal cavities were found in calcium alginate beads and the cylinder holes were observed in zinc alginate beads from the SEM,which indicated that the volume of fraction of zinc alginate polymer was relatively bigger and the zinc alginate polymer chain was more rigid than that of calcium alginate .

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。

We speculated that ZAD domain may be related to some special physiologic or metabolic processes in insects. The distribution of C2H2 ZFP genes in the genome was investigated.

除了具有锌指结构域外，部分锌指蛋白还含有其它类型的结构域，被称为锌指偶联结构域，它们能辅助锌指蛋白激活或抑制目标基因表达。

It utilizes the NH3-NH4CL solution to smelt the flowers of zinc and the ash from the lead factory and the zincic industry waste residue and so on.

本发明公开的&一种湿法炼锌工艺&用NH3-NH4CL溶液浸出氧化锌、锌焙砂、铅厂烟灰、含锌工业废渣。

Groups were feeded with routine dietary(Zn37.15mg/kgDM),among which,group A was used to as the control group andB,C,D groups were added 120mg/kg,240mg/kg,360mg/kg Zn-Met in routine dietary. Pretesting date was 10 days.

各组奶牛均饲喂含锌量37.15mg／kg的基础日粮，其中，A组=基础日粮；B组=基础日粮+120mg／kg蛋氨酸锌；C组=基础日粮+240mg／kg蛋氨酸锌；D组=基础日粮+360mg／kg蛋氨酸锌，预试期为10天。

The impedance spectra are analyzed using an equivalent circuit containing two Nerstain diffusion terms. The simulated data are also discussed. Those additives can decrease the charge-transfer resistance and oxygen diffusion resistance.As to button zinc-air battery, we improve its zinc anode structure through granulation process.

结果表明：在间歇通O2的情况下，锌层大部分被腐蚀，而且在基体上有一些红锈和黑锈产生，镀锌板表面的腐蚀产物呈现着不均匀的针状物；而在间歇通N2时，镀锌板的锌层脱落面积较少，基体上没有产生红锈，腐蚀产物呈大块状；在间歇通O2和通N2的情况下，镀锌板的腐蚀速率先增后降，在200 h时，前者的腐蚀质量损失速率是后者的2倍左右；镀锌板附着库尔勒泥浆时的腐蚀过程受氧去极化过程控制。
