relative roughness meaning in Chinese
相对糙度
相对糙率
相对粗糙度
相对粗糙率
Examples
- It is validated that the numerical methods can absolutely predict the flow in the microchannels . the flow field around the roughness and the pressure drop of midline along flow direction are analyzed . it ' s found that the range of the pressure drop change relate to the magnitude of relative roughness , the distance between two parallel planes , the re number and ratio of the size of roughness and the distance between two roughness
通过对粗糙元周围流场和充分发展段中心线压力曲线的分析，发现有粗糙元存在的两平行平板间微通道，其充分发展段压降大于光滑平板充分发展段压降；当相对粗糙度和re不变时，随着板间距的减小，粗糙度对主流的影响不断增大；当板间距和相对粗糙度不变时，在层流状态下，粗糙度对流动的影响不随re的变化而变化；当板间距和re保持不变时，相对粗糙度越大，其对流动的影响就越大。 - According to the existing studies of the basic law of fracture seepage , there are two sharp contrastive relations between seepage discharge and aperture : super - cubic and sub - cubic . similarly , there are also two opposite relations between seepage discharge and relative roughness : positive and negative relations
2 、现有的裂隙渗流基本规律的研究成果中，渗流量与隙宽出现两种截然相反的关系：超立方和次立方关系；渗流量与相对粗糙度也存在两种相反的关系：正相关和负相关关系。
