grain fragmentation

基本解释

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.
利用石膏原矿中各种杂质矿物的硬度、粒度差异，通过破碎、分级方法可有效提纯石膏，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.
这类岩石缺乏面理构造，是由于矿物颗粒的脆性碎裂，旋转以及颗粒边界的磨擦滑动和扩展而造成的。
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通过有效的压缩完全避免了对细微空闲内存空间的分配，这不仅大大简化了收集器，而且还消除了潜在的碎片问题。
