前言 一个理想的低温结构支承元件,应该使通过它的热量和冷量都是微乎其微的。它不因冷热变形而变化,又只有较好的承载能力。这种支承元件对一般车间,通用实验室的要求是能满足的,以致于可以说接近理想的了。
Preface An ideal cryogenic structural support element that minimizes the amount of heat and cooling that passes through it. It does not change due to hot and cold deformation, but also has a good carrying capacity. The requirements of such support elements for general workshops and general laboratories are met so that it can be said to be close to the ideal.
