[求助] 纳米颗粒对木塑材料结晶性能的影响求解惑！！

　　　The lower crystallization enthalpy of the wood plastic composite shows that wood fibrils act as nucleating agents and allow chains packed easily around the particles. The composite filled with nano wollastonite shows higher value of crystallization enthalpy than the PP–wood sample.It could be due to restriction of chain mobility as a result of strong interaction between chains and nano particles which partially prohibits chains from forming crystals around nucleus in comparison with wood plastic composite.
However, nano wollastonite particles increase percentage of crystallinity in the composite. It could be due to high specific surface area of the nano filler which involved more chains to attain crystals around nucleus
　　木塑复合材料的更低的结晶焓显示出木纤维作为成核剂，使分子链更加容易的在粒子周围聚集。纳米硅钙石填充的木塑复合材料相比于木塑复合材料具有更加高的结晶焓，这可能是因为分子链和纳米粒子之间的强相互作用，使得链段的运动受到限制，进而一定程度上阻止了分子链在原子核的周围形成结晶。
　　然而纳米硅灰石颗粒增加复合材料的结晶度。主要是由于高比表面积的纳米填充物捕获了更多的链在原子核周围形成结晶。

　　我怎么觉得这两句话自相矛盾，前一段说分子链和纳米粒子之间的强相互作用使得阻止了分子链在原子核的周围形成结晶。后一段又说纳米粒子捕获了更多的链在原子核周围形成结晶。是我翻译错误吗？？希望哪位大神来解惑。
