From the sea ice motion data extracted from the MODIS and AVHRR images, it is found that the sea ice motion in the Bohai Sea is effected not only by prevailing winds but also by topographic steering, ocean currents and internal ice stresses. The extracted sea ice drift is similar to observed ice drift, and can clearly show the sea ice drift in the Marginal Ice Zone especially. It can compensate for the limitation of the local or single station observation.

利用MODIS和NOAA/AVHRR资料获取的渤海冰速资料的综合分析显示：渤海海冰运动，除受盛行风控制外，还受到复杂的海岸地形、流和冰内应力的共同作用，所得到的大范围海冰运动规律和多年历史观测资料分析结果基本一致，并清楚地显示了冰边缘带海冰运动的特征，弥补了局地、单站海冰观测的局限性。

ABSTRACT: A Rockwell PowerFlex7000 Variable Frequency Drive is used in JiuZHou Electric medium voltage drive test bay as the converter. Because of it belong to the current source drive, it has the function of the four quadrant, it can achieve the energy feedbackmake the motor brake,also has the advanced vector control technology, so it can achieve all kinds of load test, there are no other drives can replace it in simulate motor load. PowerFlex7000 drive has ability to achieve the full load test before the drive leave factory.
