在马尔库松(Marcusson)研究组份分析以后,提出了许多方法。其中有些方法与马尔库松观点相似,有些方法不同于马尔库松的观点。某些相似的方法却代表着沥青岩石成因问题中极不相同的观点。 沥青A和沥青B 在1901年0.Rau注意到如果将操作时通常的大气压力换成“大气压力的话,那么用苯从煤中萃取的沥青物质的量会大大增加。F.Fiscehr和W.Glund建议用50—55大气压力。在通 After analysis of the Marcusson study components, many methods have been proposed. Some of them are similar to Marcuse’s point of view, and some are different from Marcuse’s point of view. Some similar methods represent a very different view of the cause of pitch rock. Asphalt A and Asphalt B were in 1901. Rau noted that the amount of bitumen extracted with coal from coal would be greatly increased if the atmospheric pressure at operation was changed to “atmospheric pressure.” Glund recommends using 50-55 atm
