负偏析(Compared with S-stirring, a wider equiaxed crystal zone can be obtained with less negative segregation by M-stirring. 与采用二次冷却区电磁搅拌相比，结晶器电磁搅拌可以获得较宽的等轴晶区和较轻的负偏析。)
【连】 负滑脱(【技】在连铸过程中，当结晶器下振速度大于拉坯速度时，则铸坯相对于结晶器作向上运动，这种运动称之为负滑脱或负滑动。: In oscillating with negative strip, the friction alternates from positive (vertical tension on the shell) to negative (vertical compression) during each cycle. 在负滑脱振动时，每一振动周期内的摩擦力方向都是由正(铸坯壳受垂直张力)转变为负(铸坯壳受垂直压力)。)
负滑脱时间(① A more meaningful method of quantifying negative strip is to calculate the negative strip time, NSt. 定量表示负滑脱的一个更有意义方法是计算负滑脱时间 NSt。②The negative strip time (tₙ) is defined as the amount of time during the oscillation cycle when the mold travels in the cast direction at a greater velocity than the cast speed. 负滑脱时间的定义为：在一个振动周期内，结晶器在拉坯方向上以大于拉坯速度运动的时间。)
