Phonological Alternations In Tangut

西夏字書文海、文海雜類與同音是研究西夏語的重要資料。作者撰寫本論文的目的是（一）根據這些字書探索西夏語的同源詞（二）使用蘇聯索孚諾夫（M. V. Sofronov）的擬音描述這些同源詞音韻轉換的型式。本文探討西夏語的音韻轉換，共分四個項目：聲母、介音、韻母、及聲調。舉了二百八十九組音韻轉換的例子。

The Tangut dictionaries Wen-hai (the Ocean of Characters), Wen-hai Tsa-lei (the Ocean of Characters, Mixed Classes), and T'ung-yin (the Homophones) are important sources of information on the Tangut language. The purpose of this paper is (1) to list the etymologically related words from these dictionaries and (2) to describe the types of sound alternations, using Sofronov's reconstruction. These alternations are discussed under four headings: initials, medials, finals, and tones. Altogether 289 examples are given in this paper.
