摘要：
The analysis of relative accelerations and the definition of relative strains among a set of comoving particles are discussed. In particular, the strains have an observer and frame-dependent character so that for their measurements it is important to specify both the observer congruence (i.e. the kinematical status of the observer) and the transport law of the adapted reference spatial triad along the observer congruence itself. Applications to special congruences of test particles in flat space-time are then briefly presented.
