1·In addition, the viscosity-reducing effect of high temperature steam and CO2 is achieved by breaking asphaltenes'alkyl-side-chain and by changing micellar structure.

此外，高温蒸汽可能通过使沥青质发生烷基侧链断裂反应降低沥青质含量而CO2通过溶解作用改变胶团结构来实现降黏作用。

2·The results showed that, the micellar systems possess viscoelasticity, shear-thinning property and net-work structure.

结果表明，胶束体系具有较强的粘弹性、剪切变稀特性和网络结构。
