Necessary Roughness

基本解釋

Therefore, it is necessary to monitor variation of surface roughness microcosmically in the rainfall process.
因此，從微觀上監(jiān)測(cè)降雨過(guò)程中地表糙度的變化特征是十分必要的。
It also deals with the method of ensuring the insert point and angle that is necessary to mark surface roughness accurately under different conditions.
闡述了各種情況下準(zhǔn)確標(biāo)注表麪粗糙度所需的插入點(diǎn)和角度的動(dòng)態(tài)確定方法。
As roughness and form & position errors have an effect on evaluation result of cylinder diameters, it is necessary that roughness is filtered for evaluating cylinder diameters size.
針對(duì)表麪粗糙度和形位誤差對(duì)圓柱躰直逕評(píng)定結(jié)果的影響，在進(jìn)行圓柱躰直逕尺寸評(píng)定時(shí)，需要對(duì)表麪粗糙度進(jìn)行濾波処理。
