The minimum and maximum resistivity was obtained as 133.340 and 133.906 μΩcm respectively. A maximum near 340 K on the plot of temperature dependence upon resistivity is an anomaly that seems to be neceessary for any further study. 收稿日期: 1986-05-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 谭志诚 王庄 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I5/146 1 谭志诚;周立幸;陈淑霞;尹安学;孙毅;叶锦春;王秀坤,中国科学,B辑,(1983) ,№6,497． 2 1964 Book of ASTM Standards, 8, Publ.
