oriented crystallization meaning in Chinese

定向结晶化

Through the research on the crystallite of the composites modified with silicone coupling agent and pp - g - mah , research showed that the size of the crystallite and oriented crystallization had obviously influence on the mechanical performances . the sem results showed that nano - sio2 was dispersed well in pp , which promoted the matrix undergo shear yielding rather than brittle fracture
通过对硅烷偶联剂?马来酸酐接枝聚丙烯共聚物作为界面改性剂改性pp微晶的研究，表明微晶尺寸变化与复合材料的力学性能有关；在界面附近形成择优取向的结晶层，促使基体发生屈服变形，提高了复合材料的韧性。
