摘　　要：在射频肼中,观察到两个相隔很近的射频共振吸收峰.适当改变囚禁电压、检测频率等条件时,两峰相对移动或演变为单峰,其特征可由两异荷离子云的耦合运动加以描述.Two closely locating peaks of ion signals in an rf trap have been observed by rf absorption detection. The two peaks shift regularly and transit to a single peak under certain condition when the voltage of the confining field or the frenquency of the detection field varies appropriately. The feature and tendency of the signal variations can be explained by a generalized model of two coupling hetero-charged ion clouds.
