晶体的结构 meaning in English
crystalline structure minerals etc
Examples
- After geometry optimization , their energy band structure , densities of states were calculated and analysised . we also calculated the model of doping cr , which can change the energy band structure of cdgeas2 , the result is valuable for decreasing optical absorption . through the energy analysised , it was suggested that a germanium - on - arsenic anti - site defect was the most possible defect which may be associated with the 5 . 5 micron absorption , the result of analysis are agreement with the research of epr , so the calculates are accurate
