标题： Detection of a flow induced magnetic field eigenmode in the Riga dynamo facility

摘要： 在里加钠动力设施的一项实验中，检测到一个缓慢增长的磁场本征模态，持续时间约为15秒。 对于略微降低螺旋桨转速的情况，额外的测量表明该模态出现缓慢衰减。 测量结果与增长速率和频率的数值预测结果令人满意地吻合。 显示英文摘要

摘要： In an experiment at the Riga sodium dynamo facility, a slowly growing magnetic field eigenmode has been detected over a period of about 15 seconds. For a slightly decreased propeller rotation rate, additional measurements showed a slow decay of this mode. The measured results correspond satisfactory with numerical predictions for the growth rates and frequencies.
