虽然,在此不能详细报导试验低温下材料的机械特性所使用过的各种设备。但是,可以扼要地谈及一些所使用过的主要型号的装置。单轴拉伸试验是最广泛用来获得基础与设计两种数据的技术。很多各种不同的拉伸低温箱均为此目的而采用的。除许多实验者天赋喜爱设计它们自己的设备外,还有更基本的理由是广泛发展低温系统。在最通常 Although, it is not possible here to report in detail about the various equipment used to test the mechanical properties of materials at low temperatures. However, it is possible to briefly mention some of the major models used. Uniaxial tensile testing is the most widely used technique for obtaining both basic and design data. Many different types of stretching cryostat are used for this purpose. In addition to the talent many experimenters like to design their own equipment, there is a more fundamental rationale for the widespread development of cryogenic systems. In the most common
