自六十年代中期板块构造学说诞生以来,关于板块运动的力学机制问题一直没有很好解决。大洋中脊是公认的重要板块分界线,也是全球连续性最好的最长的板块分界线,对大洋中脊应力性质的认识将有利于我们探讨全球板块的运动机制。海底扩张学说为我
Since the theory of plate tectonics in the mid-1960s, the mechanics mechanism of plate motion has not been solved well. The mid-ocean ridge is a recognized important plate demarcation line and the longest plate demarcation line with the best continuity in the world. Understanding the stress properties of the mid-ocean ridge will help us to explore the global plate movement mechanism. The theory of submarine expansion is me
