Since the announcement of the theory of Special Relativity by Albert Einstein in 1905, the discussion of the Clock Paradox or the Twin Paradox has become a fervent and controversial subject, but very few have offered quaatitvely satisfactory explanations.

• 自从爱因斯坦于1905年发表了狭义相对论的论文之后,时钟佯谬或双生子佯谬便成了一个热烈争议之课题,许多文献广泛地讨论了这个问题,但很少有定量地令人满意地阐述。 其所以产生佯谬的原因,是由于不能正确应用相对运动这个概念以及对惯性系与非惯性系之间区别缺乏正确的了解。
