摘要: The statement in Rindler's book "Essential Relativity" [(Springer-Verlag, New York, 1977), p. 119] claiming that "the metric coefficients are time-independent if light signals tracing out the same path always take the same coordinate time" has two problems, the first one has been pointed out by us in a recent paper "relation between choosing ‘good' coordinates and the behavior of light signals" [Acta Physica Sinica (Overseas Edition), 3(1994), 881], while the second is the main focus of the present article.
