体积电导率 meaning in Chinese

bulk conductivity
volume conductance

This demonstrates that gpp molecules have intercalated into the nanoscale interlayers of graphite sheets as well as the pores ( from nanoscale to microscale ) of eg networks . the large structure - occupation of the formed eg - gpp networks results in low ? c , high b and excellent conductivity of the nanocomposites , for instance , the electrical conductivity at room temperature is up to 2 . 49x10 - 3 s / cm at 3 . 90 vol % eg content . 2
证明gpp分子通过溶液插层已充分插入eg网络纳米尺度的石墨片层之间和从纳米到微米尺度的孔隙之中，所形成的eg ? gpp复合网络具有大的结构占有体积，因而材料具有低_ c 、高b和优异的导电性， 3 . 90vol eg含量下，室温体积电导率达2 . 49 10 ~ ( - 3 ) s cm 。
