摘要翻译:
在496和1173赫兹的双共振扭转振荡器上,研究了300mK以下相同圆柱固体的非经典转动惯量分数。在35毫克以下,在足够低的边缘速度下,分数是相同的。在35 mK以上,高模态比低模态的分数更大。低模的耗散峰出现在比高模低4mK的温度下。这两种模式的驱动关系表明,分数的降低是由临界速度、非振幅或加速度所表征的。

英文摘要:
The non-classical rotational inertia fraction of the identical cylindrical solid $^4$He below 300 mK is studied at 496 and 1173 Hz by a double resonance torsional oscillator. Below 35 mK, the fraction is the same at sufficiently low rim velocities. Above 35 mK, the fraction is greater for the higher than the lower mode. The dissipation peak of the lower mode occurs at a temperature $\sim$ 4 mK lower than that of the higher mode. The drive dependence of the two modes shows that the reduction of the fraction is characterized by critical velocity, \textit{not} amplitude nor acceleration.
