The pyrolysis behavior of Ni─Ca‐loaded Yunnan brown coals (Shi Caoxing [SCX] and Guo Jiashan [GJS]) was studied in a fixed‐bed reactor to investigate the effects of Ni, Ca, and Ni─Ca loading on the yields of the obtained liquids and light aromatic hydrocarbons. Structural variations of the prepared coal chars were characterized by the scanning electron microscope–energy dispersion X‐ray, Fourier‐transform...
In EMC study, the interaction of two-antenna system is usually described with isolation between antennas. In this paper, the authors point out the definition of traditional isolation between antennas is unreasonable and it will give incorrect isolation prediction. We put forward definitions of arbitrary isolation, ideal isolation and practical isolation of antennas according to three states of antenna...
