摘要
研究了采自四川鱼田堡、南桐和青年等三个煤矿的煤样的大分子结构,建立起了煤的结构模型。在此基础上对煤在外电场的极化特征进行了实验研究和理论分析,结果表明,转向极化和空间极化是引起通过煤样中的电流发生衰减的本质原因,且空间极化是煤极化的主要形式。
The macromolecular structures of coal samples collected from Yutianbao, Nantong and Qingnian coal mines in Sichuan were studied and a model of structure for these coals was set up. On the basis of above mentioned work,experimental studies and theoretical analyses were made to investigate the characteristics of coal polarization in applied electric field. The results indicate that the rotation polarzation and the space polarization are the essential reason for the attenuation of electric current through coal samples,and that the space polarization is the main form of coal polarization.
