日本工业技术院电子技术综合研究所和日本大学互相交换信息,且分别独自使用储氢合金试制了各自的新型制冷机。储氢合金具有在低温下吸收氢、在高温下放出氢的性质。电子技术研究所则是以吸收和放出氢时所产生的气压差作为驱动源,实现了60.2K的最低温。另外,日本大学利用当对充装于细管内 Nippon Institute of Technology Institute of Electronic Technology and the University of Japan to exchange information with each other, and respectively, using their own hydrogen storage alloy trial of the new refrigerator. The hydrogen storage alloy has the property of absorbing hydrogen at a low temperature and discharging hydrogen at a high temperature. Electronic Technology Institute is based on the absorption and release of hydrogen produced by the pressure difference as a driving source, to achieve the lowest temperature of 60.2K. In addition, Nihon University fills in thin tubes
