查询词典 voltaite

With a purity of 94.1% and 74% respectively, voltaite crystal and solid FeCl3 have been produced by crystallizing in a lower temperature following the vaporization of the wastewater, with 70% iron and 96.5% potassium recovered. No need of high temperature and pressure, and with high efficiency, low energy loss and less pollution, this process proves its effectiveness.

用硫酸酸浸废液蒸发结晶后，铁的回收率为70%，钾的回收率为96.5%，整个工艺无需高温，无需加压，操作简单，具有高效、低能耗、低污染的特点，表明用本项技术处理酸浸废液行之有效。

The strong acidity, Fe(superscript 2+) and rather lower concentration of alkalis ions are responsible for voltaite, not jarosite, crystallizing from the acidic iron-bearing water.

分析认为，废液呈强酸性、溶液中存在大量Fe(上标 2+)、碱金属离子含量偏低是蒸发结晶过程中形成绿钾铁矾而不是黄钾铁矾的主要原因。

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。
