查询词典 reflectivity

The results indicate that an even layer of nickel was plated on expanded graphite. Ni accounted for 94.12% and P accounted for 5.88%. The reflectivity was increased in the near infrared region. The magnetism capability was enhanced. The magnetization and the retentivity were 26.3 Am^2/kg and 8.1 Am^2/kg respectively. The σ/σ was 0.31. The obtained material belongs to soft magnetism material.
