研究结果表明：改性后的煤沥青不仅出现大量的中间相小球，而且耐热性优良，可作为炭材料优质的基体前驱体。

It was indicated that the modified coal pitch, which had not only a great deal of mesophase microbead but good thermostability as well, can be qualified to be an excellent carbon precursor.

保持基本相同的焦炭质量，配入中温沥青后可以适当减少优质焦煤、肥煤的配量，降低配合煤成本。

Maintaining basically same quality of coke, the mixing of medium temperature pitch can appropriately reduce the mixed volume of high quality coking coal and fat coal, decrease the cost of mixed coal.
