In adding - acid system : the resistivities of different lithotypes " cp tend towards being constant and equal when weight percentage of aniline exceeds 50 % ; because of the structure difference of different lithotypes, the polymerizing places and processes are different ; the resistivities of vituain / pan and fusain / pan reach the lowest point respectively when ( ntloisiog / an is 0. 6, 1. 0 ; the resistivities of cp decline fast and tend towards being constant along with the reduction of diameter of coal. in not adding - acid system : the resistivities of different lithotypes ' cp decline evenly ; it is found on the crossed experiment of cp, that ( nflsaog / an mole proportion is the most important factor to influence output ratio of cp and the weight percentage of aniline is the most important factor to influence resistivities of cp. according to the result of the crossed experiment of cp
