The PQR shall include the composition and flow rate of the shielding and inert gas backing, when used. 焊接工藝評定記錄單上應包括封底焊時(shí)所用的惰性保護氣體組成成分和流率。
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，在進(jìn)入交通流率與離開(kāi)疏散率相等時(shí)動(dòng)態(tài)同步綠燈帶寬分配的指標表現最佳。
Rates of flow are represented by the slopes. 流速由斜率模擬。
A low rate is enough to prevent flushing of reductants. 緩慢的流速足以防止還原劑的散失。
