氧化物薄膜

It shows that the thermionic emission current can be influenced by the temperature, the work function, the diameter of the surplus RE particleand the electric field. The "nanometer particles" theory modification concentrates mainly on two parts. First, the active layer was described.

对"纳米微粒子"发射模型进行两方面的完善：其一、描述了表面活性物质层是非连续的薄膜；其二、当稀土氧化物晶体中的氧缺位浓度超过临界值的时候，即开始有纳米稀土粒子的形成和生长。

与对照、聚乙烯塑料薄膜包装相比，4℃贮藏的前12天，真空包装能较好地保持鲜切芋头的可溶性固形物含量和淀粉含量，褐变度、丙二醛含量和多酚氧化酶的活性较低，而超氧化物歧化酶活性较高。

Antimony doped tin oxide nano-powder was prepared by hydrothermal synthesis.

锑锡氧化物(antimony doped tin oxide，简称ATo)是一种n型导电材料，具有优良的导电性能和光学性能，被广泛地应用于各种平板显示器…、太阳能电池川、电致变色功能薄膜、红外遥感探测等领域。

The process of YSZ electrolyte thin film made by tape casting from nanocrystalline powders were researed. Comparing to the properties of adobes manufacturing by tape casting process from different grains, as a result, the larger particles within the range of nanometer may easily from the highdensity adobes.

引 言固体氧化物燃料电池(solidoxidefuelcell，SOFC)中的ZrO2电解质层越薄，其各种损耗越小，表现在电池性能上越好，因此电解质的薄膜化一直是人们关注和研究的热点[1]。

The iron hydroxide particles prepared above were coated with cobalt by surface adsorption-precipitation reaction. The low pH and Co〓 concentration of suspended system can prevent the nanoparticle from heterocoagulation. The saturation magnetization of MP particles with uniform cobalt hydroxide layer is 10％ higher than that of the α-Fe. And a close SiO〓 layer can improve the coercivity by about 92％.

铁黄粒子表面吸附-反应沉积钴过程中较低的pH值和浓度有利于形成均匀的钴氢氧化物包覆层，可避免形成异相凝聚现象，使比饱和磁化强度提高10％；表面包覆二氧化硅形成致密的薄膜，使矫顽力提高92％。

The results showed increased manganese solids composition percentage with higher iron and manganese oxidation efficiency. The results show higher oxidation efficiency could be proved by the lower residual manganese concentration in water.

在SEM/EDS观测滤纸上的沉淀物中发现，薄膜表面锰氧化物的组成比例有增加之趋势，表示氧化效果越佳，此结果也可由残余锰浓度相互印证。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
