摘　　要：文章叙述了一个金属箔同轴分流器的结构和设计方法,刻度表明,该分流器的上升时间约2ns。从动力学的角度出发,推导出了同轴分流器的一个新的强度公式,它比Park公式更符合于实验结果。A foil coaxial shunt with a risetime of 2ns has been developed to measurethe diode currents. Based on the principle of dynamics, the mechanical strength ofthe shunts for high impulse currents has been analysed. A new strength formulafor the maximum allowable current of the shunt is derived. The formula showsthat the maximum allowable current of a foil shunt depends not only on the para-meters of shunt, but also on the duration of the measured impulse current. Thecalculated values with this formula are in better agreement with the experimentalresults than Park's ones.
