使用ＳＥＭ研究了在高真空强静电场下等规聚丙烯薄膜微晶生长的形态．实验发现，在高真空强静电场下，等规聚丙稀薄膜微晶沿静电场方向生长成树枝状，而未经静电场处理的薄膜，其微晶向四月均衡生长成树枝形球晶，无取向．
The morphology of crystallite growth of the isotactic polypropylene film under high vacuum and strong electrostatic field was investigated by SEM. The experimental results show that under high vacuum and strong electrostatic field, the isotactic polypropylene film crystallites grow into dendrites along the electrostatic field, while the films without electrostatic field process grow into the dendritic spherulites evenly in April, No orientation.
