It is founded that land bitumen,the oxides of petroleum and oil soaked sandstone are of high reduction and precipitation ability to U,Mo,Se,V and Re,and fairly important to uranium metallogeny.
研究证实,石油的氧化物——地沥青及部分油浸砂岩对U、Mo、Se、V、Re等元素具有较强的还原沉淀能力,从而构成了砂岩型铀矿床成矿作用的重要环节。
Combining with the engineering example of the system of vacuum intruded pitch that has been designed for Baotou iron and steel company heat—resistant material factory,the method of eliminating pitch smoke to provide reference for similar problems in engineering design has been investigated.
结合笔者所作包钢耐火厂真空油浸系统消烟除尘实例，对沥青烟的消烟方法加以讨论，以供工程设计类似问题作参考。
