grain roundness
解釋
顆粒圓度-
3. at the same holding time, when the holding temperature changed, the number of the long equal - area - circle diameter grain increased, and the average of the equal - area - circle diameter lengthened, the average of the roundness heightened
3 、相同保溫時間條件下，改變等溫溫度，等積圓直徑大的晶粒隨溫度的升高而增加，球狀化程度高的晶粒數增多，平均等積圓直徑和平均球化度同時增大。 -
The activity area of sediment and solution in gooey is distributary river, which has gigantic water power, good degree of sorting and roundness, gruff grain. lower mud and mica content
分流河道的主體部位水動力較強，分選性和磨圓度較好，粒度粗，雲母礦物和泥質含量較低，是膠結物沉澱和溶解的活躍區，因而也是物性相對較好的地方。 -
These balls are made in a shorter process so the cost is significantly lower than round balls. for larger grain grinding or where roundness is not important, short headed balls are an excellent alternative choice. these balls have a flat area on both poles and they also have three different finishes
打頭珠都沒有經過圓磨製程，因此成本比圓珠低很多，對于較粗糙粒度的研磨或使用6mm以上尺寸的研磨鋼珠都可以考慮使用打頭珠，不但可以達到與圓珠相差不多的研磨效果，卻可以節省大量耗材成本。 -
The equal - grain - area - circle diameter and the roundness were defined to scale the form factor and quantified the degree of the grain ' s globalization. metallographic analysis, xrd, tem and edax were expired to observe the evolution of the microstructure, the changing of the phase and the changing of the component
定量測試晶粒的等積圓直徑和球化度等形貌參數，比較形變組織的半固態球化效果，採用金相分析、 xrd 、 tem 、 edax等方法觀測組織演變過程特點，並考察第二相及微區成分的變化。
