在分析电铸析氢反应及其对电铸层影响的基础上，重点研究磨擦辅助电铸中游离粒子磨擦的驱氢作用。
Based on the analysis of hydrogen evolution and its effects on deposit, the hydrogen adsorption resistance of free particle polishing during electroforming was researched emphatically.
试验发现，游离粒子磨擦能彻底消除析氢的不利影响，利用磨擦辅助精密电铸技术能够制造出没有任何麻点、针孔等缺陷的镍电铸层。
It was found in experiments that the particle polishing could eliminate the passive effect of hydrogen evolution and nickel deposits electroformed without pinholes and pits could be achieved by APEF.
附加体，游离体某些细胞的遗传粒子，尤其是细菌细胞，能够自动存在于胞质中或成为染色体的一部分。
A genetic particle of certain cells, especially bacterial cells, that can exist either autonomously in the cytoplasm or as part of a chromosome.
例如，背景粒子和一个与中性伴子碰撞而反冲的原子核相比，前者将造成更多的游离。
For example, background particles tend to produce more ionization than a nucleus recoiling from a neutralino collision.
