摘要
本文从生产型煤和型焦的需要出发,研究岩浆变质作用所形成的天然焦炭和高、中变质煤的显微结构.并提出选择粘结剂的三条要求。
The paper studies the microstructures of the cokeite and the high, middle metamorphic coal , formed by the metamorphism of magma in view of the need for producing moulding coal and coke. Three requirements to select the bonding agent are put forward as well.
