结果表明，炉管的氧化机理主要是金属离子穿过氧化物层的扩散并在氧化物—气体界面发生反应。
The results show that oxidizing mechanism of the heater tube is mainly diffusion of metal ion passing through oxide and its reaction at the oxide-gases boundary.
它可以减少液体、固体和气体界面间的表面或界面张力，容易在水或其他液体中混合或扩散，因而广泛应用于环境保护等领域。
It can reduce the surface tension between liquid, solid or gas. Because of being mixed or diffused easily in liquid, it has been widely used in environmental protection.
水合物生成是典型的界面传递输运现象，而气体迁移性质是这种传递过程的决定性因素。
Hydrate formation is a typical phenomenon of the interface transfer, and the nature of gas migration is the decisive factor for this transfer process.
