- 用LEI光譜方法測量的稀土元素Ce、Lu的檢測限優於在火焰中的原子吸收光譜方法和ICP-AES方法,Ce、Lu、的檢測限分別為4ng/ml、8ng/ml。The detection limits of Ce, Lu by using LEI spectrometry method is lower than AAS (atomic absorption) in flame and ICP-AES. The lowest detection limit of Ce obstained in this work was 4ng/ml and the lowest detection limit of Lu was 8ng/ml.
- 結果表明:微量稀土元素Ce的加入可以提高Cu-Cr-Zr合金的強度、硬度和耐熱性,抗拉強度可達637MPa,導電率為82.16%IACS,相對於Cu-Cr-Zr合金強度提高了56MPa,而導電性略有降低。With adding trace rare-earth element Ce, the results showed that the strength, hardness and heat-resistance of Cu-Cr-Zr alloy were improved, and tensile strength was enhanced to 637 MPa that was increased 56 MPa compared with Cu-Cr-Zr alloy, but the electrical conductivity of Cu-Cr-Zr-Ce alloy was 82.16%25IACS which was a bit lowered.
