线压力 meaning in Chinese

linear pressure

Linear presures in padders of dyeing and finishing machinery
染整机械轧车线压力
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。
