摘　　要：同时的相对性、钟慢效应和尺缩效应是狭义相对论时空观的主要内容.鉴于同时性是时空测量的基础,本文从同时的相对性出发详述了对钟慢效应和尺缩效应的再认识:钟慢效应是运动时钟走时率变慢和校表问题的综合表现,其实质是同时的相对性在时间量度上的直接反映;尺缩效应的实质是同时的相对性在空间量度上的反映,也是不同观测者对同一客观事实的不同时空描述.Relativity of simultaneity, time dilation and length contraction effect are among the main conclusions of special relativity. In the light of the fact that simultaneity is the foundation of space-time survey, we have explained our recognition on the time dilation and length contraction in more detail on the basis of relativity of simultaneity in this paper. The time dilation effect is a general reflex of the slow tempo of the mobile clock and different clock calibration in different inertial reference frame, and the essence is the direct reflection of relativity of simuh aneity for time-measurement ; while the essence of length contraction is the reflection of relativity of simultaneity for space-measurement, as well as the different spatio-temporal description of the same objective fact by observers in different inertial reference frame.
