The molecular formula and structural parameter of 17 coals and their preheated samples were estimated by our method presented in this conference held last year. A relationship between the number of aromatic rings, or R, and fluidity of the coals and their preheated samples were investigated. When R exceeded three, the fluidity was detected. It attained maximum when R was around four, then decreased with R, and disappeared at more than eight.
