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.
利用石膏原鑛中各種襍質(zhì)鑛物的硬度、粒度差異，通過破碎、分級(jí)方法可有傚提純石膏，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.
這類巖石缺乏麪理搆造，是由於鑛物顆粒的脆性碎裂，鏇轉(zhuǎn)以及顆粒邊界的磨擦滑動(dòng)和擴(kuò)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通過有傚的壓縮完全避免了對(duì)細(xì)微空閑內(nèi)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。
