低温恒温器简介

Brief introduction of cryostat

在低温领域中,经常需要对低温恒温条件下样品的各种低温性能,如热物理性质、机械性能、光学物理性能、磁热性能及超导性能等进行测试。这就需要提供一种实验装置来维持样品的低温恒温条件。而低温恒温器是一种能够提供低温恒温条件并与外界热绝缘的低温装置,它应用广泛,是进行低温实验的必要设备。主要介绍了低温恒温器的概念、应用、分类、结构及其设计。

In the field of low temperature, we often need to test various low - temperature properties of the samples under the conditions of low temperature, such as thermal physical properties, mechanical properties, physical properties of optical, thermal properties of magnetic, superconducting properties and so on. And cryostat is a low - temperature device that can provide low and constant temperature and thermal insulation from the external environment. It widely used in low temperature experiments and is essential for them. This paper mainly introduces the concepts of cryostat, structure, application, classification and design.
