金属化

The results showed that the impedances of composite electrodes continuously increased with increasing of immersion time.

结果表明，随浸泡时间的延长，复合电极体系的阻抗不断增大；在浸泡初期，复合电极体系的阻抗谱中即出现了低频扩散阻抗，认为该阻抗由金属表面钝化膜的溶解产物的传质引起。

It is shown that the formation process of iron carbide converted from hematite using H〓-CH〓 mixtures consists of several steps: reduction of iron ore, cracking of methane, and carburization of metallic iron.

试验发现赤铁矿与H〓-CH〓气反应制备碳化铁的过程是分步完成的，第一步是赤铁矿的还原，第二步是甲烷的裂解，然后是金属铁的碳化。

Methods Solid-tumor-bearing mice were produced with Lewis lung cell and randomly divided into radiation group (n=18) and control group (n=17).The mice in the radiation group were irradiated by 30 Gy X-ray. The expressions of E-cadherin and MMP-9 were detected by immunohistochemical. Results After two weeks of therapy.

建立Lewis肺癌模型，将荷Lewis肺癌的C57BL/6雄性小鼠35只随机分为照射组(n=18)和对照组(n=17)，照射组接受30 Gy的X线肿瘤局部照射，对照组不接受照射，2周后采用免疫组化法检测瘤组织中E-钙黏素蛋白和基质金属蛋白酶－9(MMP-9)蛋白的表达。

In different fields: harbour, iron and steel, metallurgical, cementworks, woodworks, and in the ecological field in the biggest and most modern plants for the burning and recycling of all kinds of waste. Its advanced know-how is a quality guarantee for its whole production range. EUROMEC's technical

她为多个不同行业机构生产供应物料处理的机器，包括港口，钢铁业、金属业、水泥业、木材业以至为生态行业中的大型和先进厂户提供废料被焚化及循环再造的设备，由于她拥有先进的技术，不单是品质的保证，还可进行全面化的生产。

Nevertheless , the basic question still remains unresolved : what kind of alloy systems can be formed into metallic glass and what kind of metallic glasses are likely to be the stablest .

然而，对于什么样的合金体系可以形成金属玻璃即合金系的玻璃化能力问题

And the O-O technology is used in the analysis of harbor crane models.

全面分析了面向对象的特点、对象模型的关系、结构化分析方法的特点，将面向对象技术应用于港机智能CAD模型分析，并建立了港机的总体部分、行走机构、起升机构、旋转机构、变幅机构、金属结构的各种设计模型。

Corrosion occurs whenever a metal ion in the solid crystalline lattice of a metal is induced to become a solvated cation

当固体晶格中的一个金属离子侵入而形成溶剂化阳离子，便会产生腐蚀。

In fact, we had obtained polythiophene films with high quality in BF3 ethyl ether, a kind of solvated Lewis acid. The electric conductivity of the polythiophene film is a bout 100 Scm-1. and the tensile strength is as high as 140 MPa, which is forty percent higher than that of aluminum.

事实上，我们已经从一种Lewis酸催化下的低电位聚合体系—噻吩/三氟化硼乙醚溶液中得到了高质量的聚噻吩薄膜，在降低了的聚合电位下得到的聚合物具有优异的力学及电学性能：拉伸强度达140MPa(比金属铝高40%)，电导率则可达100Scm-1。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
