在中俄几百年的交往过程中,边缘语满足了两国人民沟通的需要,完成了传达信息的使命。汉俄边缘语作为跨文化交际的产物,对汉、俄语言及中俄两国人民的生活产生了深远的影响。本文试对汉俄边缘语的形成背景和语言特点进行研究,分析汉俄边缘语渐趋消亡的原因。 In the course of several hundred years of Sino-Russian exchanges, the marginal language has met the needs of the people of the two countries and completed the mission of conveying information. As a product of intercultural communication, the marginal language of China and Russia has had a profound impact on the lives of Han, Russian and Chinese and Russian peoples. This paper attempts to study the formation background and linguistic features of the marginalized languages ​​in China and Russia and analyzes the causes of the disappearing of the marginal languages ​​in China and Russia.
