The calculation of inclusive spectra of pions produced in pp and AA collisions as functions of the rapidity y is presented within the self-similarity approach. It is shown that at not too large rapidities y one can obtain an analytical form of the self-similarity function \(\varPi (y,p_t)\) dependent on y and on the hadron transverse momentum \(p_t\). A satisfactory description of the data on rapidity spectra at \(|y|\le \) 0.3 is presented within the approach applied. The energy dependence of these spectra is also shown to be universal.

在自相似性方法中，提出了在pp和AA碰撞中产生的pion的包容谱随速度y的计算。结果表明，在不太快的速度y下，可以得到依赖于y和强子横向动量\（p_t \）的自相似函数\（\ varPi（y，p_t）\）的解析形式。在所应用的方法中，对\（| y | \ le \） 0.3处的快速光谱数据进行了令人满意的描述。这些光谱的能量依赖性也被证明是通用的。
