At the moment of step changing in velocity, the adjustment of lamellar spacing, the average velocity and the average interface undercooling characterize the hysteresis effect.
相对于阶跃时刻，片层间距调整、界面平均生长速率与平均过冷度的变化均具有滞后性。
2
An adjustment member allows variable spacing of the differential probing tips.
调节构件允许改变差动探测尖端的间距。
3
The results will provide important guidance for such reservoirs in later adjustment and well spacing strategy.
