| Abstract: | The influence of cake press treatment on the determination of volatile matter in brown coals was studied in the paper,and the causes of the different results between cake press treatment and un-pressed treatment in the determination of volatile matter were analyzed.Since a portion of coal samples would splash in course of determination with un-pressed treatment,it was indicated that the cake press treatment should be necessary in the determination of volatile matter. |
