中文摘要：

为准确测量重接式电磁发射装置中的脉冲大电流,设计了一个Rogowski线圈,阐明了其设计原理,分析了电流变化对Rogowski线圈本身参数（电阻、电感）的影响,并针对重接式电磁发射线圈电流的特殊性,采用了适当的外部接线方式。最后,采用此系统测量了重接式电磁发射装置中的电流,取得了令人满意的效果。

英文摘要：

In order to accurately measure the large current pulse in the reconnection electromagnetic launch（EML）, a Rogowski coil is designed and analyzed. Then the effect of current change on the parameters（resistance and inductance） of the Rogowski coil is studied, and a proper outside wiring is adopted for the particularity of reconnection EML. At last the large pulse current in a reconnection EML is measured with this system, and the result is satisfying.
