本文描述了一种适用于1K到300K的低温物理实验装置。它既可以作为液氦恒温器使用,又可以作为氦连续流动恒温器使用。如果用液氮作冷源,则可以获得77K到300K的温度。
This article describes a low-temperature physical experimental device suitable for 1K to 300K. It can be used as a liquid helium thermostat, but also as a helium continuous flow thermostat. If you use liquid nitrogen as a cold source, you can get 77K to 300K temperature.
