第二部分进行胶体金合成工作，并成将霍乱毒素单株抗体与20 nm胶体金进行抗体染色，进一步应用於霍乱毒素免疫分析试片之开发上。

The results show that the technical parameters and the concentration of sodium molybdate have obvious effect on the composition of the alloy. The crystal grain size is from 6.2 to 12.7 nm and changes with current density, temperature and the pH value of the electrolyte.The crystalline growth of the alloy accords with the model of three-dimensional growth. The surface morphology is mainly determined by the rate competitions between the growing direction of vertical surface and the expanding direction along the surface towards circumambient. The results of the X-ray data show the presence of the multiphase containing solid solution and intermetallic compound in the deposits. The deposit phases alter from the FeNi and FeMo solid solution to the FeNi and MoNi4structure at 3 A/dm2. The deposits internal stress increases linearly with the decrease of the grain size. The lattice parameter of the deposits are slightly distorted

结果表明：工艺条件和钼酸钠浓度对合金组成的影响较大；所得合金晶粒尺寸为6.2~12.7 nm，并随电流密度、温度和电镀液的pH值的改变而变化；合金的晶体生长符合晶核三维生长模型，镀层表面形貌由平行和垂直于基体的生长速度的相对大小决定；镀层物相为固溶体和金属间化合物的多相结构，当电流密度为3 A/dm2时，镀层物相由FeNi和FeMo固溶相转化为FeNi和

In this way, the Nonmonotonic Semantics (NM-Semantics) of DL+log is extended to the Nonmonotonic Circumscriptive Semantics (NMC-Semantics), and therefore, DLclog becomes the hybrid system with the stronger expressiveness and reasoning abilities.

使用这种方法，DL+log的非单调语义(NM-semantics，简称NM语义)被扩展成了DLclog的非单调限制语义(nonmonotonic circumscriptive semantics，简称NMC语义)，从而成为目前表达能力和推理能力最强的杂合系统。

As for the radius of porous media effect our experiments select four kinds of sea-sand whose pore radius vary between 125-700μm.The results shows that the pore radius we use in the experiments are too large to produce capillary effect which can clag the process of hydrate formation, only if the pore radius is smaller than 60 nm the can produce capillary effect.

基于粒径范围125-700μm的四种多孔介质的甲烷水合物生成实验结果表明，较粗粒径的多孔介质引起的孔隙间毛细作用对甲烷水合物不会产生明显的阻碍作用，但计算结果表明，孔径粒径小于60nm的多孔介质会阻碍甲烷水合物的生成。

AFM images revealed that as the sputtering time was prolonged, the film thickness increased, the film became compacter, and the specific area of the film also increased, thus, the release rate of silver ions increased, which led to improved antibacterial properties. EDX test results indicated that increase in film thickness led to increase in silver weight percentage per unit surface, causing improved antibacterial properties. Moreover, when the film thickness was 1 nm, the inhibition percentage of Staphylococcus aureus and Escherichia coli were 100%.

结果表明：随着薄膜厚度的增大，样品抗菌性能提高；溅射时间延长，薄膜厚度增大，膜层的致密性改善，单位面积上的银含量增加，膜层表面积增大，银离子释放几率增大，是提高抗菌性能的主要原因；当纳米结构银薄膜厚度为1 nm时，对大肠杆菌和金黄色葡萄球菌的抑菌率均达到100%。
