1·Undershoot Undershoot refers to the amount by which voltage or frequency drops below the nominal value as the voltage regulator or governor responds to changes in load.
下超调下超调指电压调整器或控制器在应对负荷变化时，电压或频率低于额定的量。
2·The load transfer of B0+B0-B0+B0 locomotive with different traction schemes was calculated, basing on the definition of nominal and transitional and equivalent traction height.
针对B0+B0-B0+B0轴式八轴机车不同的牵引方案，在定义了名义牵引高、过渡牵引高和等效牵引高的基础上，进行了轴重转移的计算分析。
3·With the detection system, traction load test not on the line is possible for the locomotive after mid-haul, and locomotive faults could be located as well that nominal parameters could be adjusted.
该检测系统能够满足机车中修后不上线即可进行牵引负荷试验的要求，并能够查找机车故障，调整标定参数。
