结果表明，适当磁场参数产生的电磁搅拌可以细化堆焊层的组织，而且还能控制堆焊层中陶瓷复合材料的数量、形态及分布情况，从而改善了堆焊层金属的硬度和耐磨性。

Through penetrate methods and observing microstructure,the type of corrosion is determined as intergranular corrosion.

通过材质鉴定、着色分析以及显微镜分析确定了该腐蚀的类型为晶间腐蚀，产生腐蚀的原因主要是焊接使焊缝附近的金属受热发生敏化现象以及材料本身存在的质量问题所致。

The results from the experiment show that the participancy of heated and atomizedaluminium dynamically oxidized into Al_2O_3 powder.

试验研究表明在电弧喷涂雾化气体中加入纯氧气成分后，经高温电弧热熔化、雾化的铝金属，形成细小的粒子与氧气产生强烈的氧化反应可以生成Al_2O_3粉体。

The intensity of pressure is the most markable factor that influence the casts mechanical properties and microstructure. When its value exceeds 40MPa, the disfigurement such as shrinkage porosity can be effectively reduced . when its value exceeds 120MPa, the pressure obviously influence the crystal performances of liquid metal also, and compact homogeneous exiguous equiaxial crystal can be obtained. Pressure can also increase the solubility of Cu in a -Al.

比压是对铸件力学性能和显微组织最为显著的因素，其取值超过40MPa时，能有效减少缩松等缺陷，当比压超过120MPa时，除了能减轻铸造缺陷外，还对液态金属的结晶性能产生显著影响，在铸件断面上得到致密、细小且均匀的等轴晶。

Moreover, the traditional catalytic oxidation system of isophorone contains metal and organic solvents, which cause environmental pollution.

另外传统上对异佛尔酮的催化氧化基本都是包含金属的催化体系和有机溶剂参与的反应体系，这对环境污染产生严重的影响。

The transgenic tobacco plants expressing CED-9 showed strong resistance to aluminum toxity and salt stress compared with wild plants. It was suggested that CED-9 conferred enhanced resistance to cell death induced by abiotic treatment and affected plant growth and development.

通过与野生型烟草对照，研究了CED-9基因在烟草的抗逆境中的功能，结果显示CED-9基因能提高烟草对金属Al和盐的抗性，并对烟草的生长发育产生一定的影响。

The results show that a serious decarbonizing layer in the surface of high carbon steel is produced by ion bombarding.

结果表明，在离子轰击下，高碳钢表层产生严重的脱碳层，脱碳层的存在对随后的渗金属过程有着很大的影响。

When the deal was struck in 2008 China's appetite for the metals was insatiable, but if it is scaled back or unravels, it could mark a turning point in China's quest for resources, which has threatened to marginalise western donors.

当该协议在2008年达成时，中国对金属的需求似乎是无止境的，但如果该协议缩小规模或落空，它可能标志着中国寻求资源过程的一个转折点，这一过程已产生排挤西方捐助方的威胁。

Best control and attachment is obtained if free standing junctions are first made, and then touched down to the metal surface(attached to the other welder wire) while the firing button is depressed.

如果结球一开始就已经制成，直接将其与金属表面（或与其他焊接线接在一块的）碰触，按下点火按钮就可以产生最好的监控装置。

Black is the main hue with appropriate integration of some colors with slight metal luster such as slate-color, silver and white-grey. Thus the original black generates a subtle diversification.

以黑色为主色调，适当地加入略带金属光泽的石板色、银色及白灰色，使原有的黑色产生微妙的变化。

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

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
