唐诗由于产生年代较早,在流传过程中会产生异文,这样产生的异文或与作者原字音相近同或与原字在意义上可相代替。本文主要利用在意义上可代替的异文并结合杜甫律诗中对仗的特点,归纳“霜露”一词在杜甫诗中的几种意义。“霜露”在杜甫诗中有指霜和露,单指霜和指白雾三种基本含义。 Because of the earlier generation of Tang poetry, foreign poems may be produced in the process of dissemination. The resulting foreign languages ​​may be similar or similar to the original pronunciation of the author or may be replaced in the sense of the original words. In this paper, we mainly use the different texts that can be substituted in the sense of the word and combine the characteristics of the battle against each other in Du Fu’s verses to sum up the significance of the term “Shulu” in Du Fu’s poems. “Cream dew ” in Du Fu’s poems have means frost and dew, a single finger cream and refers to the three basic meanings of white fog.
