grain diameter

基本解釋

Calculate the grain size from an image processed including grain-edge by average diameter method.
采用平均直徑法對一幅經(jīng)過處理的晶界圖像進行晶粒度計算。
Turfy not too fine, pearlite grain diameter 3 - 4 millimeter, vermiculite grain diameter 3 - 5 millimeter are idealer.
泥炭不要太細，珍珠巖顆粒直徑3-4毫米，蛭石顆粒直徑3-5毫米比較理想。
Based on analysing the gravel features, several non-conventional porosity laboratory prediction methods, such as CT scan, image analysis, grain statistics, full-diameter analysis, have been described.
在總結分析礫巖特點的基礎上，簡要介紹了包括CT掃描、圖象分析、粒度統(tǒng)計、全直徑分析等幾種非常規(guī)孔隙度實驗估測分析方法。
