摘要：

It is noted that the Heisenberg uncertainty relations set a lower bound on the product of variances of two observables A, B when they are separately measured on two distinct, but identically prepared ensembles. A new uncertainty relation is derived for the product of the variances of the two observables A, B when they are measured sequentially on a single ensemble of systems. It is shown that the two uncertainty relations differ significantly whenever A and B are not compatible. © 1977 the Indian Academy of Sciences.
