It has a close-packed hexagonal crystal structure.
它有密排六方晶体结构。
2
In the hexagonal closepackedstructure, slip systems are more limited.
在六方密排晶格中，滑移系受到较多的限制。
3
The high stability and close-packed assembly were interrupted with increasing the chain length, and the co-existing self-assembly structure of the single molecule and dimmer was formed.
