两性金属

Corrosion caused by a reaction of an amphoteric metal with the alkaline products of electrolysis.

由于两性金属与电解碱性物质的反应而引起的腐蚀。

As an amphoteric metal, aluminium reacts both in the acidic and alkaline range, it is therefore important that, when formulating the coating, the pH value is in the 7 - 8 range.

作为一种两性金属，铝反应，无论是在酸性和碱性范围内，因此，这是重要的是，在制定涂料， pH值在7 -8范围内。

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。
