"Metallic bond",The positively charged ion cores are held together by mutual attraction to the electron, thus producing a strong metallic bond.

"，"带正电荷的离子核，彼此相互吸引对方电子，因此产生很强的键接称为金属键。

The alloy catalyst shows good stability for CO_2 reforming of CH4 during whole test period. The catalytic performance for Ni/Sn alloy is similar to the monometallic Ni .The formation of graphitic carbon was not observed.

在CH4的CO_2重整实验中，在800℃，CH4/CO_2=50：50时，Sn含量为1wt%的Ni/Sn合金催化剂稳定运行48小时无积碳产生，其催化活性与纯金属Ni相似。

No adjustable nosepiece design , but suitable for strong static electricity places .

无鼻梁金属条设计，适用于产生强静电场所，佩带方便，有良好的视野，安全舒适，呼吸阻力小，过滤效率好，且有良好的吸汗功能。

A phenomenon called self-induction is at work here: as the current oscillates, the magnetic field around the wire changes, too, inducing voltages that slow the oscillation.

这里运用了一种「自感现象」：当电流振盪时，金属线周围的磁场也会改变，产生使振盪减慢的电压。

Semper felt that the language of architecture was born, not out of the branches of Laugier's primitive hut, but out of the artifacts—the textiles, ceramics, and metal—that were hung on the primitive wood frame.

Semper 感觉到建筑的语言生成了，但它不是在Laugier的原始小木屋上分支出来，而是产生于人工制品——编织物，陶瓷和金属制品，这些悬挂与原始木框架上。

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。
