The PQR shall include the composition and flow rate of the shielding and inert gas backing, when used. 焊接工艺评定记录单上应包括封底焊时所用的惰性保护气体组成成分和流率。
In addition, the dynamic SBA has its best performance on PIs when the incoming flow rate is equal to the dispersing rate. 除此之外,在进入交通流率与离开疏散率相等时动态同步绿灯带宽分配的指标表现最佳。
Rates of flow are represented by the slopes. 流速由斜率模拟。
A low rate is enough to prevent flushing of reductants. 缓慢的流速足以防止还原剂的散失。
