Abstract: Sentence translation goes with parsing,while the computation of in herited attribute values of symools relies on the specific parsing process. The bottom-up parsing is disadvantageous to the inherited attribute compution. The paper discusses how to solve the problem, then gives the methods of implementation, analyzes, compares and evaluates those methods.

Key words: syntax-directed definition, synthetic attributes, in herited attributes, bottom-up parsing

摘要： 在语法分析的同时进行句子翻译，此时符号属性值的计算依赖于具体的分析方法.继承属性值的计算不适合 在自底向上的分析法中实现，笔者在文中讨论了在自底向上的分析中如何处理继承属性的求值问题，给出了实现 方法，对这些方法作了分析、比较与评价
