Under water stress, The decrement of contents of chlorophyll, PS ⅱ primary photochemical efficiency ( Fv/ Fm) and photochemical quenching coefficient ( qP) were less; 水分胁迫下,徐州18叶绿素含量、光合速率、PSⅡ原初光化学效率(Fv/Fm)和光化学猝灭系数(qP)的下降较少;
The thermal stress was the primary factor affects the distortion during quenching. Plastic deformation under high temperature is the main origin of distortion. GDL-1钢淬火时的热应力是影响其变形的主要因素,高温下的塑性变形是变形主要来源。
