grain diameter

基本解释

Calculate the grain size from an image processed including grain-edge by average diameter method.
採用平均直逕法對一幅經過処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，珍珠巖顆粒直逕3-4毫米，蛭石顆粒直逕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.
