伟大领袖毛主席教导我们:“在生产斗争和科学实验范围内,人类总是不断发展的,自然界也总是不断发展的,永远不会停止在一个水平上。”低温绝热形式的发展——从高真空绝热,粉末真空绝热,到多层绝热,也完全符合毛主席的这一正确论断。 Chairman Mao, the great leader, taught us: “In the struggle for production and within the scope of scientific experiments, mankind always develops continuously. Nature has always evolved and never stops at a level.” The Development of Low-temperature Insulation Forms - From High vacuum insulation, powder vacuum insulation, to multi-layer insulation, also fully consistent with Chairman Mao’s correct conclusion.
