中文摘要:
      介绍了米制航空航天螺纹（MJ）的用途和标准起源，阐述了螺纹牙型及特性，对比美制航空航天螺纹（UNJ）及公制普通螺纹（M），分析了相同点及其特殊性，特别是其特定环境下耐冲击的承载优势，便于有关设计人员与标准使用者能从概念、形状上理解和区分相近的螺纹标准，为了解和应用米制航空航天螺纹提供参考。
英文摘要:
      The application and origin of standard of metric thread of aeronautics and astronautics (MJ) were introduced. The thread form and features of MJ were elaborated. The similarities and differences between UNJ, the metric system common thread (M) and MJ were analyzed, especially the impact resistance and load bearing. The purposes were to provide reference for understanding and application of MJ, and make it easy to understand and distinguish the standard of the similar threads for designers and standard users.
