particle settling meaning in English
粒子沉降
Examples
- In gold panning , the mixture is swirled around in a shallow pan with water , the heavier gold particles settle to the bottom and the lighter particles are washed away
淘金时，把金矿沙放在浅盘里用水淘洗，较重的金颗粒落在盘底，较轻的颗料就被冲走。 - The experimental techniques ( such as sedimentation equipment , controlling the size and size distribution of powders , the concentration of suspension ) have been devised subtly . on the basis of theoretical and densification design , the w - mo - ti fgm has been obtained by particle settling and hot pressing sintering . the structures of specimen were observed by electron probe
通过对实验工艺，如沉降设备、原料粒度及粒度分布的控制、悬浮液浓度等方面进行精细的设计，在理论设计和致密化研究的基础上，通过颗粒共沉降得到梯度沉积体，并通过真空热压烧结得到w - mo - ti功能梯度材料。 - Traditionally , solid particles of micrometer or millimeter magnitudes were mixed in the base liquid . although such solid additives may improve heat transfer coefficient , practical application are limited because of the fact that the micrometer and / or millimeter - sized particles settle rapidly , clog flow channels , erode pipelines and cause severe pressure drops
迄今为止，在液体中添加的粒子都局限于毫米或微米级，由于这些毫米或微米级粒子在实际应用中容易引起磨损、堵塞等不良结果，而大大限制了其在工业实际中的应用。 - From the particle settling point of view , the main factors affecting the compositional distributions of sediment have been analyzed . the result indicates that there exists quantitative relation between the compositional distributions of sediment and the settling quality ratio of the powders a and b . only the ratio varies does the compositional distributions of sediment change
结果表明：当有两种不同种类的粉未a 、 b共同沉降时，沉积体的组成分布与单位时间内a 、 b粉末的沉降量比存在定量关系，只有单位时间内a 、 b粉末的沉降量比变化时，沉积体的组成分布才发生变化。
