掺碳 meaning in English

acierate
carbon dosing

2 、 in order to solve the phenomenon of the outdiffusion of the base dopant , two solutions are suggested : 1 ) the sige : c base can effectively solve the outdiffusion problem ; 2 ) the undoped buffer layer can constrict the outdiffusion phenomenon
2 、为了解决基区杂质外扩现象,提出了两种方案: 1 )采用掺碳的sige : c基区层,能够有效消除外扩问题; 2 )采用未掺杂的缓冲层i - sige ,能够有效抑制外扩现象。
Then we prepared na2fepo4f cathode material coated with carbon by solid - state reaction . as cathode material , the first discharge capacity is 111mah / g and the capacity reduces to 102 . 1mah / g after 20 cycles . ultrafine na2fepo4f powders synthesized by a sol - gel process also shows a good electrochemical performance
随后采用在材料表面覆碳的方法对氟磷酸亚铁钠进行改性,结果表明当掺碳量为5 %时,电池的首次放电比容量为111mah / g ,第20次的放电比容量为102 . 1mah / g 。
