two core sediments (C1 and C2) of Xiangjiang River, Chang-Zhu-Tan region, Hunan Province, China. The heavy metal contents are relatively higher, especially for the surface or near the surface layers. The calculated anthropogenic factor values indicate that all the heavy metals except for Cr in the core samples are enriched, especially for Cd, with the maximum enriching coefficients of 119.44......

frequency and the absorption bandwidth less than -10 dB is 7.9 GHz after hydrothermal growth of 12 h. The microwave absorption is caused by magnetic loss mainly and dielectric loss secondly in the low-frequency range of 2-13 GHz, while dielectric loss mainly but magnetic loss weakly in the high-frequency range of 13-18 GHz. So, the sharp micro-octahedral Fe3O4 is an excellent microwave absorption material......
