表面结晶 meaning in English
surface crystallization
Examples
- The sem shows : the c60 thin films , which were prepared in vacuum condition , consist of spherical cluster and have an average diameter about of 20 ~ 50nm . while in gas condition , the average diameter from 50nm to 200nm , and the average diameter of particles increases with the increase of gas pressure
Sem测量表明：真空条件下制备的c60薄膜表面粒子粒径约20 50nm ；气氛(氮气和氩气)条件制备的薄膜表面粒子粒径为50 200nm ，并随气压的增大而增大，表面结晶现象也随气压增大而明显。
