Bidirectional stress systems with internal lapses are rare and their existence has been recently called into question (Newlin-Łukowicz 2012). The present paper reports an acoustic study of secondary stress in Ukrainian based on polysyllabic words with lexical stress located at or near the right edge of the word. The results indicate that Ukrainian has an iteration of secondary stresses from the left edge towards the lexical stress, rather than in the opposite direction. This characteristic makes it metrically related to bidirectional stress systems with internal lapses (e.g. Polish), which invalidates the argument against such systems and proves the empirical adequacy of the metrical theories designed to account for these stress patterns.

乌克兰语的节奏压力：双向系统的声学证据

具有内部失效的双向应力系统很少见，它们的存在最近受到质疑（Newlin-Łukowicz 2012）。本文报道了一项基于多音节词的乌克兰语次要重音的声学研究，词汇重音位于或靠近单词的右边缘。结果表明，乌克兰语具有从左边缘向词汇应力而不是相反方向的二次应力迭代。这一特征使其在度量上与具有内部失误的双向应力系统（例如波兰）相关，这使反对此类系统的论点无效，并证明了旨在解释这些应力模式的度量理论的经验充分性。
