To characterize the rhythm of stresses in a line of Russian iambic tetrameter, a frequency profile is often used, i. e., a diagram of the occurrence of real stresses on all feet (ictuses) of the verse line. This article discusses in detail one of the mechanisms that enables the speech factor to influence the formation of the stress profile. It is shown that in Russian iambic tetrameter of the nineteenth and twentieth centuries, the high frequency of stresses of the second ictus is explained by the fact that the beginning of the line more often than not coincides with the beginning of a sentence or clause, and the Russian syntagma is more frequently stressed in the middle. And vice versa, wherever the frequency of enjambments increases, the second ictus is less frequently stressed, because the beginning of the syntagma moves to the middle of the line. Considering the above, the author attempts to characterize the peculiarity of the rhythmic structure of Russian iambic tetrameter in synchronic and diachronic aspects and reveal some major large-scale trends such as the growth of the rhythmic diversity of poetic texts.

俄语 Iambic Tetrameter：其节奏结构的演变

为了描述俄罗斯抑扬格四音步中重音的节奏，经常使用频率分布图，即在诗行的所有脚（ictuses）上出现的真实重音图。本文详细讨论了使言语因素影响压力分布形成的机制之一。研究表明，在 19 世纪和 20 世纪的俄语四步抑扬格中，第二个 ictus 的高频率重音可以通过以下事实来解释：行的开头往往与句子或从句的开头重合，并且俄罗斯宪法在中间更频繁地被强调。反之亦然，只要包裹频率增加，第二个发作的压力就会减少，因为句法的开头移到了行的中间。考虑到上述情况，作者试图从共时和历时两个方面来刻画俄罗斯四步抑扬格节奏结构的特殊性，揭示诗歌文本节奏多样性增长等一些主要的大尺度趋势。
