1·The major feature of Submerged Circulative impinging Steam Reactor (SCISR) is significantly promoted micro-mixing in the impinging zone.

浸没循环撞击流反应器(SCISR)的主要特点是撞击区能显著强化微观混合。

2·The hardness of welded joints obtained by double-wire submerged arc welding is significantly better than that obtained by CO2 gas shielded. The peak hardness appears in the heat affected zone.

CO2气体保护焊接头的硬度值明显较双丝埋弧焊接头的硬度值高，硬度值在热影响区出现峰值。
