大孔结构 meaning in Chinese

macroporous structure

Leaching experiments of metakaolin show that the final al extraction rate in a batch reaction is strikingly influnced by the inferior pore struture geometry of the metakaolin pellets
在轻度润湿状态下制备的高岭石团粒，经煅烧后，仍具有发达的粒内大孔结构。
It was showed that mipm between 50 - 300 ? m with macro - pores could be prepared via both seeds swelling and suspension polymerization method and suspension polymerization method , the former method could prepared the mipm with narrower size distribution while the later one was easier to carry out and more time - saving . the morphology of the mipm was influenced by many factors including swelling solvent , stirring speed , dosage of seeds , dispersant , dilute and progenic solvent
M的、具有大孔结构的mipm ，前者的产物具有相对较窄的粒径分布，但后者的制备工艺则较简单、制备周期也较短；溶胀剂、搅拌速度、种球用量、分散剂、稀释剂和致孔剂是影响产物微球形态的主要因素；乳液聚合法能够制备得到0 . 16 - 0 . 56
