麻省理工学院的物理学家利用热图技术和无线电频率捕获了第二个声音的第一张图像，这是超流体中的波状热行为。 MIT physicists captured the first images of second sound, a wave-like heat behavior in superfluids, using a heat-mapping technique and radio frequencies.

麻省理工学院的物理学家首次捕捉到了第二种声音的图像，这是通过将原子云冷却到极低温度而产生的超流体中的波状热行为。 MIT physicists have captured the first-ever images of the second sound, a wave-like heat behavior in superfluids created by cooling a cloud of atoms to extremely low temperatures. 他们使用热图技术和无线电频率来观察热量如何在这种特殊的物质状态下像波一样移动并来回“晃动”。 They used a heat-mapping technique and radio frequencies to observe how heat moves like a wave in this special state of matter and "sloshes" back and forth. 这种热量像波浪一样流动的现象是被预测到的，但尚未被直接观察到。 This phenomenon, where heat flows like a wave, was predicted but not yet directly observed. 有了这一发现，科学家们现在可以更好地了解热量在超流体和其他相关材料（包括超导体和中子星）中如何移动。 With this discovery, scientists can now better understand how heat moves in superfluids and other related materials, including superconductors and neutron stars.
