But the volume fraction of particles in composite fabricated by prefabricate method was finite.

但是预制件法制备的复合材料的颗粒体积分数有限，无旋涡机械搅拌法的制备温度高，故这两种方法均不适合制备体积分数高（大于 20％）、颗粒尺寸小的复合材料而利用半固态机械搅拌法，能够将颗粒尺寸为3.5μm；体积分数为40％的SiC颗粒加入到金属Al中，但是当颗粒体积分数大于30％时，机械搅拌方式不能将颗粒均匀地分散在基体金属中。

After subjected to the streaming treatment, the dispersion of the loaded Mo species pronouncedly increased, and some Mo species with small particle size migrated into the zeolite channels and reacted with the Brnsted acid sites to form (Mo2O5)(superscript 2+) dimers.

经高温蒸气处理后，催化剂上Mo物种的分散度显著提高，有较多的Mo物种迁移至分子筛的孔道内，并与B酸发生强相互作用生成钼氧二聚体，有效地增强了催化剂的抗积炭能力。

Nanoparticle of an appropriate proportion were homogeneously dispersed in the PI matrix, and the interfacial adhesion between the matrix and the nanoparticle was hence strong owing to the high specific surface area and reactivity of the nanoparticle. Subsequently, the molecular chains of PI attained unchanged or even increased interaction at a proper mass fraction of the nanometer particle, which contributed to improve the wear-resistance of the nanocomposites.

采用PI的原位聚合填充方法，利用聚酰亚胺与无机纳米表面较强的相互作用（如静电作用、较强的范德华力、氢键甚至化学键的形成），用非水悬浮工艺制备了无机纳米/聚酰亚胺纳米复合材料，率先用大型分析仪器全面地表征了复合材料的结构，采用原位聚合填充法制备的聚酰亚胺复合材料中，无机纳米分散状态良好；无机纳米氧化物/聚酰亚胺复合材料的结构表征显示出PI有机相和SiO〓无机相之间形成了键联型复合体系，两相相互影响；在复合体系中，单相本体的结晶结构并未发生改变；在摩擦过程中纳米氧化物没有发生价态的转变；无机纳米氧化物的加入，提高了聚酰亚胺的耐热等级；适量纳米氧化物并不影响复合材料的机械性能， 2。
