摘要：
We consider the Adler D-function, which is defined in the spacelike region, and the e(+)e(-) annihilation ratio smeared, according to the Poggio, Quinn, and Weinberg method, which is determined for timelike argument. We show that the method of the nonperturbative a-expansion allows one to describe these Euclidean and Minkowskian characteristics of the process of e(+)e(-) annihilation down to the lowest energy scales.
