residual fraction

Results were shown as follows: more than 75 percent of total heavy metal Cd or Cu in uncontaminated soils was associated with iron oxide fraction and residual fraction.

结果表明：未污染土壤中重金属镉、铜主要为氧化铁结合态和残渣态，占土壤重金属全量的75%以上；

The thermal residual stress of low volume fraction Al2O3P/ 2024Al composites was found more even. With the volume increased, part of thermal residual stress in composites began to lap each other.

颗粒体积分数低的Al2O3P/2024Al复合材料的热残余应力场分布比较均匀，随着颗粒体积分数的增加，Al2O3P/2024Al复合材料的局部热残余应力场有相互叠加的现象。
