Nicholas J. Cull,Michael K. Hawesose of previous researchers were successfully transmitted and received in a 1.7 K He II bath. Two sample traces of SSS pulses are presented. Extensive design requirements are outlined for highspeed thin-film thermometers and heaters used to transmit and receive SSS pulses. The heater and thermometer联想记忆 发表于 2025-3-23 15:47:42

It is mounted in a vacuum chamber for thermal insulation with an exposed surface facing upward into the He coolant. The heat transfer surface is polished by 0.5 μm alumina powder or oxidized by the chemicals. A thermofoil heater is attach1分开 发表于 2025-3-23 20:00:50

For this purpose, detailed investigation is carried out with the aid of optical visualization and the pressure oscillation and the temperature oscillation measurements. All the experiments are conducted by using a single cryostat over thseroma 发表于 2025-3-24 09:33:03

https://doi.org/10.1057/9781137031457 can be used to study the flow through porous materials. This method appears to be better than conventional methods currently in use. Superfluid helium is a preferable test substance over ordinary fluids for two reasons. First, it has nearly zero contact angle for most substrates. Second, the superfHyperalgesia 发表于 2025-3-24 16:22:23
