A method of measuring moisture content of coal based on standing-wave ratio was put forward. Because the permittivity of coal was also influenced by the temperature and degree of compaction of coal, and there was a complicated nonlinear relationship among the moisture content of coal, permittivity, temperature and degree of compaction, the least squares… CONTINUE READING
