对退火后的变形铜多晶和铜单晶电阻变化的研究已有许多文献作过过论述。作者研究了经过不同温度的长时间保温后无变形丝状铜单晶的电阻稳定性。研究旨在探索用丝状铜单晶制取电阻温度计敏感元件的可能性,因为单晶金属与多晶金属相比具有更好的组织和性能稳 Many studies have been made on the study of the change of the resistance of deformed copper polycrystal and copper single crystal after annealing. The authors studied the resistance stability of non-deformed filamentous copper single crystals after long-term heat preservation at different temperatures. The aim of this study was to explore the possibility of making resistive thermometers with filamentous copper single crystals because monocrystalline metals have a better microstructure and properties than polycrystalline metals
