1·A dual-phase microstructure containing free ferrite has a lower value of adhesive force.

铁素体双相组织能降低粘附力值。

2·Composition and surface properties of obtained composite sub-micron particles have been studied in comparison with those of ferrite-free PLGA sub-micron particles.

将由此而来的混合亚微粒的组分和表面性质与不含铁氧体的PLGA亚微粒进行了对比研究。
