查询词典 impurity

The removal of these impurities by three kinds of active carbon(coaly activated carbon,fruit hull activated carbon,woodiness activated carbon) are studied under different experimental conditions.The results show that the fruit hull active carbon is not suitable for the removal of the impurity in bittern of salt lake because its removing rate of COD and turbidity is ...

以去除盐湖卤水中COD和浊度为目的，选用煤质活性炭、果壳活性炭、木质活性炭3种不同活性炭进行净化除杂的工艺研究，结果表明：果壳活性炭对COD和浊度的去除率最低，加入量最大，不宜选用；木质活性炭在低温下(≤20℃)脱除COD效果较好，在常温下(28~45℃)去除COD和浊度的效率明显低于煤质活性炭；在震荡速度、吸附时间及吸附剂加入量均相同的情况下，煤质活性炭脱色除杂效果明显优于其余两种活性炭，在盐湖卤水的脱色净化工程中应优先选用。

Accelerator mass spectrometry has ultra-high sensitivity and can be used to detect extremely low impurity contents in samples. 10Be is a cosmogenic nuclide. As a tracker, it has been widely applied to earth, environmental and cosmographic sciences.

加速器质谱计具有很高的灵敏度，能测量样品中含量极微的杂质同位素。10Be是一种宇宙成因核，在地学、环境科学和宇宙学等领域有广泛的应用，它为纯β衰变核，端点能量低且半衰期很长。

The force for filtering and backwashing is from water press and pump pressure.The pressure in filtering chamber will keep same.The solution will be filtered out from inner chamber of filtering core.The solid impurity will remain on the inner surface of filtering coThe pressure difference between outer and inner chamber and.filtering resistance will be increase.

该机的过滤和反冲洗推动力均原水压头或泵杨程提供，系统滤腔的压力基本保持恒定，液体从滤芯的内腔向外流动，夹带的固体杂质被截流在过滤介质的内表面，引起内外腔压差升高，过滤阻力逐渐增大。

Sliding bearing not only pass working force,but also sustain high surface velocity,which require the material to have soft parts,in order to obtain fine working behavior and difficulty to damnify by extra impurity,and have hard parts to acquire fine wearability and fatigue strength.

由于滑动轴承既要传递作用力又要承受很高的表面速度，这就要求轴承材料既要具有软组分，以获得良好的运行性能，如磨合性、顺应性以及尽可能小的咬和倾向，且不宜被外来杂质所损伤；又要具有硬组分，以获得良好的耐磨性和抗疲劳强度。
