From the very beginning of systematic investigation of the Russian iambic tetrameter (1910s–1940s), the proportion of stresses on the first and second ictus of the line was chosen as its main rhythmic characteristic. Meanwhile, attributing an aesthetic value to this characteristic is wrong: it is largely dependent on the changing speech norm in the late 18th an early 19th century. The general trend in the evolution of the Russian iambic tetrameter from the mid 18th to the mid 20th century can be described as an increase in the degree of rhythmic diversity of this metre. Every rhythmic form of the iambic tetrameter approximates as close as possible to the frequency predetermined by the general norms of the Russian literary language. Both processes (changes in the speech norm and the growth of rhythmic diversity of the metre under consideration) are illustrated by statistical data.

俄罗斯四分法四分仪：描述问题（新范式的前奏）

从对俄罗斯Iambic四分仪（1910s–1940s）进行系统研究的最开始，就选择了该线的第一和第二齿上的应力比例作为其主要的节奏特征。同时，将美学价值归因于此特征是错误的：它很大程度上取决于18世纪末至19世纪初不断变化的语音规范。从18世纪中叶到20世纪中叶，俄罗斯四边形四分仪的总体发展趋势可以描述为该米节奏韵律度的增加。歧义四分音符的每一种节奏形式都尽可能接近俄语文学语言一般规范所预定的频率。
