grain fragmentation

基本解釋

Based on the hardness and grain difference of all minerals in the gypsum ores, improve whiteness from 62.6% to 69.3% by fragmentation and grinding-classification.
利用石膏原礦中各種雜質礦物的硬度、粒度差異，通過破碎、分級方法可有效提純石膏，制成的半水石膏白度由62 .6%提高到69.3 %。
These rocks are lack of foliation and resulted from the brittle fragmentation of mineral grains with rotation of grain fragments accompanied by fractional grain boundary sliding and dilatancy.
這類巖石缺乏面理構造，是由于礦物顆粒的脆性碎裂，旋轉以及顆粒邊界的磨擦滑動和擴展而造成的。
G1 compacts sufficiently to completely avoid the use of fine-grain free lists for allocation, which considerably simplifies parts of the collector and mostly eliminates potential fragmentation issues.
G1通過有效的壓縮完全避免了對細微空閑內存空間的分配，這不僅大大簡化了收集器，而且還消除了潛在的碎片問題。
